Optimized Drone Based Routing System for Smart Cities

Abstract

This paper presents an AI-driven drone routing system for smart cities that optimizes delivery paths in real-time. Using Dijkstra’s Algorithm, A* Search, and Reinforcement Learning, the system considers distance, battery capacity, obstacles, weather, and no-fly zones. The proposed system reduces delivery time by 40–60% and energy consumption by 25–35% compared to traditional ground-based delivery. Simulation results demonstrate significant improvements in operational efficiency and cost reduction for urban logistics.

Introduction

The text proposes an AI-based optimized drone delivery system designed to address major challenges in urban logistics such as traffic congestion, high delivery costs, and increasing demand due to rapid urbanization.

Key Problem

Traditional ground delivery systems are inefficient in dense cities, while existing drone systems struggle with:

• Limited battery life and payload capacity
• Obstacle avoidance in complex environments
• Airspace restrictions and no-fly zones
• Weather variability
• Coordination of multiple drones

Proposed Solution

The paper introduces a hybrid intelligent routing framework that combines three algorithms:

• Dijkstra’s Algorithm for static shortest-path routing
• A Algorithm* for heuristic-based efficient pathfinding
• Q-Learning for adaptive, real-time decision-making based on environmental feedback

This combination enables both optimal planning and dynamic adaptation.

Motivation and Contributions

The system is motivated by the rise of e-commerce and the need for sustainable, fast delivery alternatives. Key contributions include:

• A hybrid multi-algorithm optimization framework
• Real-time rerouting using weather and traffic data
• Energy-aware routing to extend drone battery life
• Multi-drone coordination for collision avoidance

Literature Review Summary

Previous approaches include:

• MILP-based optimization: accurate but too slow for large-scale use
• GPS-based systems: real-time but lack obstacle awareness
• Vision-based systems: accurate but computationally heavy

The main research gap identified is the lack of a system that balances real-time performance, scalability, and efficiency, which this paper aims to solve.

Problem Statement

The system addresses:

• Efficient route optimization under constraints
• Battery-aware navigation
• Real-time environmental adaptation
• Safe multi-drone coordination

Methodology Overview

The system pipeline includes:

• Data collection (GPS, weather, traffic)
• Preprocessing into graph representations
• Routing using hybrid AI algorithms

Conclusion

This paper presented an optimized drone routing system using AI and reinforcement learning. The system dynamically opti- mizes flight paths based on real-time data. Key contributions include: 1) Hybrid approach combining Dijkstra, A*, and Q-Learning 2) Comprehensive cost function with multiple factors 3) Real-time dynamic rerouting capability 4) Scalable multi-drone coordination The proposed system achieves 40–60% reduction in delivery time, 25–35% energy savings, and 30–45% cost reduction for smart city logistics.
