Water data communication is a potential technology to realize underwater communication. The experiment of underwater data communication in the laboratory is different with that in the real water environment because the physical scale is limited. Although since recent several decades, artificial scattering agents are used to recreate underwater data communication through water channels under different communication medium conditions, but the similarity between experimental water and natural water is not reliable, such as the similarity in frequency domain characteristics. The underwater transmitter directs a signal to the water\'s surface, causing tiny vibrations that correspond to the transmission. Above the surface, a highly sensitive receiver reads these minute disturbances and decodes the signal.
In recent years, underwater activities and related wireless communication have drawn great interest from both academia and industry. Wireless communication involves no physical link established between two or more devices, communicating wirelessly. To explore and acquire data from ocean efficiently and safely, it is essential to establish communication links between underwater platforms and terrestrial platforms. Radio frequency wave (RF), acoustic wave and optical wave are three existing wireless carriers for transmission in the air and water. Although RF signal can travel a long distance and achieve a high transmission rate in the air, they can only propagate few meters through water due to high absorption and attenuation. Acoustic wave can travel several kilometres in the water and has been the prime choice for underwater communication. However, the transmission rate of an acoustic communication system is only in the order of kilobits per second, which cannot reach the requirements of potential applications. Underwater wireless communication plays a crucial position in marine activities which include environmental monitoring, underwater exploration, and clinical records collection. Underwater wireless communications nonetheless continue to be pretty challenging, because of the precise and cruel situations that signify underwater channel.

II. LITERATURE SURVEY
AUTHORS: Tianrui Lin, Nuo Huang, Chen Gong, Jianghua Luo
In this paper, they establish a water-to-air visible light communication (VLC) link using green light emitting diode (LED), and investigate the coverage characteristics of the designed water-to-air -VLC link under calm and wavy water conditions. By transmitting a high-frequency sinusoid signal, we extract the variation of link gain. Based on the received signals of an experimental water-to-air -VLC system, we obtain the real link gains at different receiver points and analyze the channel temporal properties in good link conditions (called link “on” state). It is seen that the mean channel gain under wavy water surface condition can be larger than that under calm water surface condition, especially when the transmitter and receiver are not perfectly aligned, due to the random spatial modulation effect of wavy water surface. Moreover, the “on” state duration and interval can be well fitted by a shifted exponential distribution and a shifted lognormal distribution, respectively. Bit error rate result reveal the effect of expanded link gain variation under wavy water surface condition. This work provides significant guidance for future works on the communication protocol design and related performance analysis.
2. Title: Internet of Water Things: A Remote Raw Water Monitoring and Control System
AUTHORS: Abílio c. da silva Júnior, Roberto Munoz
The scarcity of the planet's water resources is a concern of several international entities and governments. Smart solutions for water quality monitoring are gaining prominence with advances in communication technology. This work's primary goal is to develop a new online system to monitor and manage water resources, called Internet of Water Things. The proposed system's objective would be to control and manage raw water resources. Thus, it has developed a platform based on the server-less architecture and Internet of Things Architectural Reference Model, in which it is applied in a simulation environment, considering several electronic devices to validate its performance. For this research, there is a system for capturing raw water from tubular wells. Each well has a level sensor, a temperature sensor and a rain gauge.
The data is collected every minute by an electronic device and sent every hour to the Internet of Water Things system. From data analysis, the amount of memory allocated to functions minimally interferes with efficiency. The Internet of Water Things system, applied in a real case, consists of connecting a device installed in a water well to the platform, where the data is transmitted through a 3G network and then processed. Thus, the proposed approach has great potential to be considered a complementary tool in monitoring raw water and assisting in decision-making for the management of water resources.

4. Title: IoT based Water Parameter Monitoring System
AUTHORS: Krishna S, Sarath T V, M S Kumaraswamy, Vishnu Nair
With the ever-rising pollution of water bodies caused by human-made actions as well as natural calamities, water monitoring systems are the focal point for society. Water-related application has much potential for automation. With the advent of big data analytics, there is a multitude of verticals in water quality, smart irrigation, and smart water distribution network. All of these works well with accurate and real-time data. The requirements for multiple sensor parameters and robust communication framework that can be extended to various domains of water monitoring applications are the most critical hindrance for the development of an automation application in this domain. This work proposes a system that overcomes these problems. With the use of an industrial multi-parameter sensor node, EXO Sonde the desired sensor values can be extracted from the physical world. The sensed data is processed and communicated forward to the server forward through a layered architecture to a server. The sensor node utilizes a file system to save the sensor data in case of network loss. The communication technology between nodes and sensors is GSM. In the server, the data gets stored and gets visualized in a web UI.
5. Title: Smart Water Meter using Power Line Communication (PLC) Approach for measurements of Accurate Water Consumption and Billing Process
AUTHORS: Abdul, Shaik Asif Hussain, Ajay Rana
Data transmission methods have been evolved drastically with the development of internet. Data transmission methods are of two types. One is wired and the other one is wireless networks. Power line communication is considered as one of the tools that is used for power transmission using special type of modems that takes the data with known frequencies. The paper proposes smart water meter that uses flow sensor that collects household water consumption. The proposed system will be set to a threshold limit where the water is cut-off using electronic valve. The collected data will be sent to data centre for data analysis through grid power line using PLC modem. The data center further forwards the water billing department for billing purposes through SMS and then it will be sent to user mobile number. The proposed work aims at increasing accuracy of reading and collection process. The benefit of this work is reduced human intervention and measuring tools.
6. Title: The Internet of Things (IOT) Based Smart Rain Water Harvesting System
AUTHORS: Vardhaman Ranjan, Mohd Irshad, Neetu Joshi
Ground water all over India is depleting fast. Niti Aayog has cautioned that Delhi could run out of ground water by 2020. This is a critical situation and can happen with other parts of India too. Conservation of water is the need of hour. Due to vast globalization, urbanization and modernization the quality of our surrounding is degrading which in turn is affecting the natural phenomenon of raining too. The gases such as Sulphur Dioxide and Nitrogen Dioxide released due to burning of fossil fuels gets transported by air and wind currents.
They mix with water and other material to form sulphuric acid and nitric acid causing acid rain. The problem in harvesting arise here as this water is not suitable for use. Storing this water in the same reservoir with slightly better quality of water can lead to degradation of that water also. Out of 1200 millions of gallons per day demand of water, 200 MGD requirement of Delhi is met by illegal boring of water. Under a regulation of 2012, it has been made mandatory for all establishment above 100 sq. m to have rain water harvesting system. Small size houses already constructed also need to be addressed. A major issue is not only harvesting of water but also the quality of harvested water. Present paper seeks to find answer to all these problems.
7. Title: Dynamic Optical Wireless Communication Channel Characterization Through Air-Water Interface
AUTHORS: Tianrui Lin; Chen Gong; Jianghua Luo; Zhengyuan Xu
In this paper, we consider an optical wireless communication system model whose channel consists of three parts: underwater channel, atmosphere channel and the interface between air and water. To better approximate the reality, besides the effect of random air-water interface, we consider the impact of ocean current which leads to misalignment between the transmitter and receiver. On the basis of this model, we explore the communication viability and simulate its link gain and time delay. Monte Carlo simulation results show that the dynamic air-water interface extends the communication opportunities, especially when there is no direct path between the underwater nodes and airborne base station.
8. Title: Citizens’ campaigns for environmental water monitoring: lessons from field experiments
AUTHORS: Andreja Jonoski1, Thaine H. Assumpção, Iouliani Theona, Chrysovalantis Tsiakos, Maria Krommyda
Advanced sensing technologies, combined with wireless sensor networks, have already demonstrated their value in monitoring urban water systems, where management is rather centralized within water utility organizations. Environmental water resources, characterized by more diverse stakeholders and overlapping management responsibilities of different agencies, present more challenging contexts for implementing novel sensing technologies. Crowdsourcing by citizens has been proposed as an alternative approach for adaptive data collection that can augment the amount of data collected, as well as bring together the diverse stakeholders and citizens in more participatory water resources management processes. This article first introduces the challenges of designing citizens' campaigns for collecting data on environmental waters. A set of developed mobile phone and web applications is then introduced, integrated within a specific platform, as it was used in the execution of citizens' campaigns for data needed in flood analysis and management. Experiences and lessons learned are presented from the field execution of citizens' campaigns in two pilot areas located in Europe the Danube Delta in Romania, and the Kifissos catchment in Greece. Two of the campaigns are on river data collection - water levels and water velocities, and two on collecting land use/land cover data. Surveys carried out with campaign participants indicate their appreciation of the initiative, but challenges remain regarding user-friendliness of the applications. Logistic issues such as timing, duration, and pathways for data collection impacted the motivation of participants. Overall, a unique and large dataset was obtained in terms of quantitative water measurements, despite data losses due to low raw data quality. Further work lies in evaluating the usability of this dataset for local authorities.
9. Title: LED-based Underwater Wireless Optical Communication for Small Mobile Platforms: Experimental Channel Study in Highly-Turbid Lake Water
AUTHORS: Chang Shu, Chunlei Zhang, Wei Zhang, Wei Wei, Wei jiang, Qiao Xiaorui
Underwater collaborative work between small mobile platforms (SMP) such as divers, litter submarine or AUV, requires a high data rate communication system which is compact, reliable, affordable and eye-safe. The high bandwidth of LED-based underwater wireless optical communication (UWOC) is an advantage. Artificial, emulated as well as simulated, turbid underwater channel has been studied recently, but no practical nature water. To fully meet the requirements of challenging turbid underwater channel scenarios for SMP, we demonstrated a green LED-based UWOC system up to a bandwidth of 3.4 MHz in a highly-turbid nature lake water. Through a contrast wireless optical communication (WOC) experiment in air, turbid water channel is observed to compensates the receiving signal amplitude attenuates after propagating a longer attenuation length due to multiple-scattered light caused diffusion, and thus to be more like a single-input multi-output system. From our experimental observation, the single-input multi-output channel model could be employed not only in turbulent UWOC, but also in highly turbid UWOC.
Moreover, turbid water channel is observed a “frequency selection” effect, thus LED with lower threshold voltage at higher frequency would optimize bandwidth and link range, and a robust pre-code for interference cancellation would be a well-direct choice to constructing different UWOC system in highly turbid water for SMP. Our finding will provide a new reference complementing the current LED-based UWOC systems in realistic water environment.
10. Title: Smart City Wireless Connectivity Considerations and Cost Analysis: Lessons Learnt from Smart Water Case Studies
AUTHORS: Parag Kulkarni, Tim Farnham
According to estimates from the United Nations, while the world population is likely to reach 9 billion by 2050 (from around 7 billion today), the water resources available to cater to this population are likely to remain similar to what they are today. Therefore, there is a growing concern to reduce water wastage and improve the efficiency of water distribution systems, in particular, urban water systems given the proliferation in both the number of cities that are springing up and the number of people moving to live in cities. Motivated by this, the European Commission under the aegis of the Framework Program funded the Information and Communications Technology Solutions for the Efficient Water Resources Management project. This Smart Water project is aimed at investigating the role of ICT in monitoring and efficiently managing urban water systems, in particular, exploring the deployment of sensors, communication technologies, and associated decision support systems in utility providers water networks geared toward addressing problems, such as leakage management, demand management, asset management, and so on. This article elaborates on the wireless connectivity considerations, proposes a total cost of ownership framework for evaluating candidate solutions, and highlights experiences from Smart Water case studies involving two utilities in Europe.
III. PROPOSED SYSTEM
A. Existing System
In existing system, data transmission is mainly accomplished using SONAR and Radio frequency waves. In water acoustic communication has low data transmission, minimum range and multipath reflection. The highspeed communication in under water acoustic channel is difficult because of restricted information measure and severe fading. Radio waves (3-30 kHz) can penetrate seawater to a few dozen of meters and a submarine at shallow intensity can use them to communicate. A deeper vessel can use a buoy ready with an antenna on a protracted cable. In underwater optical communication water could be a medium that extremely absorbs optical signals. The particles present in the sea causes optical scattering which leads to a disadvantage in existing system.
B. Proposed Design
The proposed system aims to transmit data using water as a communication medium. In underwater, data transmission with those on the land are pretty difficult as both of them uses different signals that only work in their corresponding mediums. Radio wave which travels through air medium die very quickly in water medium. In this proposed system image transmission through water communication is done by having two separate modules in water. The two modules are transmitter (TX) and receiver (RX) modules which can transmit and receive data/image in the water respectively. In order to increase the speed and quality of data transmission ATMega328 microcontroller is used. To secure the data during transmission in water, data is encoded in the transmitter end and decoded in the receiver end during communication.
a. The communication between underwater devices or marine divers or submarines and to those on land will be easy.
b. In this type of data transmission, the aquatic organisms and their habitat is not affected.
c. Power consumption of this system is low compared to other types of transmission.
a. It is used by the military, to conduct underwater surveillance, as well as to detect intrusion.
b. Underwater wireless communication is also used in environmental monitoring and collecting of oceanographic information.
c. Autonomous underwater vehicles have also been deployed in finding crashed aircrafts; and investigation into the causes of their crash.

D. Working Of Proposed System
In this project, they develop a system that can transfer data wirelessly from one end to other. Here water acts as a communication medium through which the image transmission is carried out. As shown in block diagram (fig 3.1&fig 3.2), our system comprises of couple of ATMega328 micro controllers. This system consists of both transmitter and receiver module. In the transmitter end they using microcontroller, LCD display, Water data communication transmitter module, UART port, Visual basic software. The image which needs to be transferred is obtained from the user and is encoded using visual basic 6.0 and sent to the microcontroller using UART port. The encoded image is then sent to the receiver module using Water data communication transmitter module. Then the receiver end consists of microcontroller, LCD display, Water data communication receiver module, Visual basic software. The encoded image which was transmitted is then obtained by the water data communication receiver module. The encoded image is decoded using visual basic 6.0 and displayed at the receiver end.
E. Module Description
All electronic circuit works only in low DC voltage, so we need a power supply unit to provide the appropriate voltage supply for their proper functioning. This unit consists of transformer, rectifier, filter & regulator. AC voltage of typically 230volts rms is connected to a transformer voltage down to the level to the desired ac voltage. A diode rectifier that provides the full wave rectified voltage that is initially filtered by a simple capacitor filter to produce a dc voltage. This resulting dc voltage usually has some ripple or ac voltage variation. A regulator circuit can use this dc input to provide dc voltage that not only has much less ripple voltage but also remains the same dc value even the dc voltage varies somewhat, or the load connected to the output dc voltages changes.
2. USB 2.0 TO RS-232 Serial Cable
USB 2.0 to RS-232 Serial Cable is used for serial data transmission. It is a form of communication. Simply it is called as serial connection. It provides the connection between USB and the traditional RS-232 serial port. PLCs use RS232 to talk to other modules or even other PLCs. These modules can be anything that also uses RS232 such as, operator interface or HMI, computers, motor controllers or drives, a robot, or some kind of vision system.
The RS232 cable allow the computer to give commands to the any kind of vision system via a voltage signal. The vision system then deciphers those commands and completes the process. USB 2.0 to RS-232 Serial Cable is shown in fig3.3.
