摘要： 无线传感器网络中ReInForM多路径协议能保证网络可靠性,但未考虑节点能量动态变化和通信路径工况,随机选取下一跳转发节点的方式使得部分节点因被反复使用而快速失效,缩短了网络生命周期。针对该问题,在蚁群优化算法的基础上,结合蚁群信息素浓度和节点剩余能量等因素,提出一种ReInForM协议多目标优化条件下的动态路由选择算法,将能耗和剩余能量作为多路径选择指标,共同决定下一跳最优节点。仿真结果表明,与原有ReInForM路由算法相比,该算法能够在保证数据传输可靠率的同时,更有效地均衡节点能耗。

Abstract: ReInForM routing protocol in Wireless Sensor Network(WSN) only guarantees network reliability without considering the dynamic changes of node energy and communication path conditions.The way of selecting the next hop forwarding node randomly makes some nodes fail quickly because of repeated use,and further shortens the network life cycle.To solve the above problems,this paper introduces Ant Colony Optimization(ACO) algorithm and combines ant pheromone concentration and node residual energy to construct a ReInForM dynamic routing selection algorithm under the condition of multi-object optimization.It takes the energy consumption and residual energy as the path selection indicators to determine the optimal next hop.Simulation results show that,compared with the original ReInForM routing algorithm,the proposed algorithm can effectively balance the node energy consumption while ensuring the reliability of data transmission.
