摘要
在LEACH协议中,簇头与基站之间采用单跳方式,导致了部分簇头能量衰减过快,从而影响到无线传感器网络的性能。针对该缺陷,进行基于蚁群算法的LEACH协议改进研究,该研究在保留蚁群算法多跳路由的基础上,对启发函数引入了剩余能量因子,改变了簇头的跳跃位置和信息素浓度建立与更新的过程。经过仿真实验,网络首节点死亡时间推迟了23%,网络的生命周期延长了7%,基站的信息传输量提高了17%。
In the LEACH protocol, a single hop method is used between the cluster head and the base station, which causes the energy of some cluster heads to decay too quickly, thus affecting the performance of the wireless sensor network. Aiming at this defect,this paper studies the improvement of LEACH protocol based on ant colony algorithm, on the basis of retaining the multi-hop routing of ant colony algorithm, the study introduces a residual energy factor into the heuristic function and changes the hopping position of the cluster head and the process of establishing and updating pheromone concentrations. Through simulation experiments,the death time of the first node of the network is delayed by 23%, the life cycle of the network is prolonged by 7%, and the information transmission volume of the base station is increased by 17%.
