| 摘 要： | LEACH协议中的簇头和基站采用一跳通信，导致能量消耗过快。为此，提出一种基于蚁群算法的无线传感器网络(WSN)能量预测路由协议。引入蚁群算法思想，簇头节点通过多跳方式与基站节点进行通信。在计算蚂蚁选择下一跳的概率时，考虑节点可能的能量消耗，避免路径选择过于集中。仿真结果表明，该协议能降低簇头能量消耗，延长网络寿命。

| Abstract: | The energy of cluster-heads is consumed rapidly because all cluster-heads directly sent data to sink in LEACH protocol. Aiming at this problem, this paper proposes a Wireless Sensor Network（WSN） routing protocol based on Ant Colony Algorithm（ACA） with energy forecast. As the ant colony algorithm, cluster-head sent data to sink by multiple hops transmission, the new algorithm predicts energy consumption of nodes when it calculates probability of next-hop. Simulation results show that the new algorithm can avoid route over-concentration, reduce cluster-heads energy consumption, and prolong the network lifetime. |
