For wireless sensor network node energy, communication ability is limited, etc.So Proposed an improved ant colony optimization routing algorithm , full consideration of the communication between nodes from the distance between the nodes may increase the energy dissipation of nonlinear growth, and energy consumption and the next hop communication residual energy node.Make the wireless sensor network routing in communications, energy consumption and network survival, approximate periodic optimal value.The simulation results show that this algorithm can effectively reduce the energy consumption and network node number and data transmission path length, prolong the wireless sensor network survival period.%针对无线传感器网络节点能量、通信能力有限等特点,提出了一种改进蚁群优化的路由算法,算法对下一节点的选择充分考虑了通信距离和剩余能量等因素,将蚂蚁搜索行为集中到最优解附近,为避免早熟收敛行为的发生,将信息素轨迹的值域范围进行限制,通过对信息素轨迹的平滑化,快速逼近无线传感器网络最优路径;仿真结果证明,该算法有效地减少了网络能量消耗、节点死亡数量和链路长度,延长了网络生命期.
