Abstract: In order to improve the wireless sensor network path optimization efficiency, quick to find the optimal path, based on ant colony-genetic algorithm sensor path optimization method.Using genetic algorithm is proposed to fast the global search ability and ant colony algorithm for positive feedback mechanism, to realize the integration of the two algorithm.Simulation results show that the ant colony-the genetic algorithm in time and performance is better than the single ant colony algorithm and genetic algorithm, can quickly find wireless sensor network optimal path, prolong the network lifetime.
