Abstract
The radio transceiver typically consumes most energy,so the design of energy efficient routing protocols is of great importance.This paper firstly analyzed the topology of wireless sensor networks(WSNs) and constructed a routing model for WSNs,and then integrated the basic principle of genetic algorithm into the model,proposed an algorithm to solve the multi-path routing optimization problem.The presented algorithm adopted variable-length chromosomes to encode the problem,applied selection,crossover and mutation,made full use of the information and function of the base station,and implemented the global optimization for the multi-path routing in WSNs.Simulation results show that the global optimization can effectively prolong network lifetime and improve the network performance for WSNs.
