针对无线传感器网络中节点能量受限的特点,将蚁群优化算法(ACO)应用于无线传感器网络,同时考虑了通信路径长度和节点剩余能量等因素,提出了具有能量意识的无线传感器网络路由算法,从多方面解决了节点间的能耗不均衡问题.该算法在OMNET+ +平台下仿真结果表明,与Ant-Net、ACRA算法相比在能耗不均衡和传输延迟等方面有了较大改进,实现了全网节点的能耗均衡,有效延长了网络生命期,减小了传输时延.

As the limitation of energy of wireless sensor network node,this paper introduced the ant colony optimization algorithm(ACO),proposed a power-aware routing algorithm(PARA) based on ant colony optimization, it considered the communication distant of routing and the rest energy of communication sensors to solute the energy unbalance from various aspects.The simulations in OMNET+ + show that gets obvious improves against Ant-Net and ACRA in the imbalance of energy consumption,transmission delay, balancing energy consumption between nodes and prolonging network's life period.
