The Research of Wireless Sensor Networks Routing Protocol Based on Optimized Ant Colony Algorithm

چکیده
For wireless sensor networks, the core issue is to design an energy-efficient network protocol as far as possible. Ant colony algorithm has proved to be effective in prolonging the network’s lifecycle and ensuring the reliability of data transmission. In conditions of network topology’s dynamic changes, we optimized the basic ant colony algorithm and introduced the pheromone broadcasting mechanism to improve the routing protocol’s performance. And we analysed the ant colony algorithm’s realization mechanism in TinyOS. The simulation test of the routing protocol is proceeded on the TOSSIM platform. Results show that the optimized ant colony algorithm can choose the shortest path while balancing network energy consumption. The proposed routing protocol prolongs the lifecycle of the entire network, and also better adapts to dynamic changes of the network structure. Keywords-wireless sensor networks, ant colony algorithm, routing protocol, TinyOS, TOSSIM simulation
