摘要
由于传感器节点能量的有限性,如何延长网络的生命周期是无线传感器网络(WSN)路由设计的主要目标.为解决LEACH协议存在簇头分配不均匀和能量消耗较大等问题,研究一种基于蚁群算法的无线传感器网络路由设计方法.主要采用节点能量来选举簇头,采用蚁群算法优化簇间路由以实现簇间通信.仿真结果表明这种方法优于LEACH算法,在降低能量消耗与延长网络生存周期等方面具有更好的性能.
For the sensor node with energy-limited, how to prolong the lifetime of Wireless Sensor Network(WSN) is the primary target for routing design on Wireless Sensor Network(WSN). To solve the cluster-heads maldistribution and large energy consumption in WSN with LEACH protocol, a method for WSN routing design is studied based on the ant colony algorithm, which includes the cluster-head selection in accordance with node energy and inter clusters communication by using the ant colony algorithm to optimize the routing of inter clusters. The simulation results show that the method is superior to LEACH algorithm, and has better performance in minimizing energy consumption and prolonging the lifetime of network.
