摘要
针对无线传感网络节点能量有限的特点,提出一种改进的蚁群算法,将蚂蚁信息素、网络节点能量和节点间的时延相结合,形成算法控制因子。仿真结果表明,该算法可以均衡网络中各个节点的能量消耗,延长整个网络的生命周期,缓解网络拥塞并降低平均传输时延。
Aiming at the limitation of energy of Wireless Sensor Networks(WSN) node, this paper proposes an improved ant colony algorithm. The ant pheromone, the energy of the node and delay between the nodes are combined to engender algorithm control gene. Simulation results show that this algorithm can balance energy consumption between nodes in the network and prolong the lifecycle of the whole network, relieve network congestion and reduce the average transmission delay.
