摘    要:提出一种能量均衡的无线传感器网络蚁群优化路由协议EAntWSN。该路由算法基于节点的剩余能量选择下一跳节点,并提出路径平均能量的思想进行信息素的更新,使用计算有效的蚁群智能路径搜寻方式,找到从源节点到汇聚节点的最优路径,完成网络的通信任务。仿真结果表明:优化的蚁群算法节约了网络中节点的能量消耗,延长了网络的生命周期。

Abstract: An Energy-balanced routing protocol based on ant colony optimization for wireless sensor network (EAntWSN) was proposed. Choosing next hop to send data packet was based on node residual energy and updating pheromone was depended on the idea of path average energy. Computationally effective ant colony intelligence was used in the routing to find the best path from source nodes to sink node and accomplish network communication task. Simulation results indicate that the optimal ant colony algorithm saves energy consumption of nodes and prolongs the network lifetime.
