摘　　要：路由选择问题是无线传感器网络中的核心问题。针对无线传感器网络节点能量、计算能力和通信能力有限等特点,为了降低能量开销和延长网络的生命周期,将蚁群算法和移动代理技术结合。提出一种新的无线传感器路由算法。考虑节点之间的距离、路径能量消耗和节点剩余能量情况,使网络中的能量消耗更加均衡,同时对蚁群信息素更新规则进行了改进,加快了蚁群算法收敛到最优解的速度。仿真结果表明,与其它移动代理路由算法相比,算法在全局性和收敛速度方面都有所提高,有效地减少冗余数据传输,降低通信消耗,延长网络的生存周期,为路由传感器设计提供了参考。Routing selection is the core problem in wireless sensor network,for wireless sensor network node energy,computing power and communication ability are limited.In order to reduce energy costs and prolong the lifecycle of the system,a new wireless sensor routing algorithm is proposed in this paper based on the ant colony algorithm and mobile agent technology.This algorithm considers the distance between nodes,energy consumption and node path in the same time,and makes residual energy of energy consumption more balanced.The update rules of ant colony pheromones were improved,and the converging speed to optimal solution of ant colony algorithm is accelerated.Simulation results show that compared with other routing algorithms,the global convergence speed of the algorithm has improved,redundant data transmission and consumption of network communication are reduced effectively,and prolong survival period,is very suitable for large-scale use wireless sensor network.
