摘要
针对无线传感器网络节点能量有限和网络拥塞问题,采用一种基于蚁群系统的能量均衡多路径路由协议。在路由发现过程中,综合考虑节点最小剩余能量和平均剩余能量,通过跨层设计模型获取节点距离信息和节点队列长度作为启发式函数,利用蚁群系统的特点形成多路径的数据传输。仿真结果表明,该路由协议在端到端传输时延和能量均衡等方面优于其它协议。
Aiming at solving the energy limitation of node and network congestion in wireless sensor networks,an energybalanced multi-path routing protocol based on ant colony system（ACSBMR）was proposed.During the routes discovery process,both the minimum residual energy and the average residual energy of nodes were involved,and the heuristic function consisted of the distance information and the queue length between adjacent nodes which were obtained through using the cross layer design model.Thus multiple routing paths were established by taking advantages of ant colony system.Simulation results indicate the proposed protocol is better than other protocols in end to end transmission delay,energy balance and so on.
