Ant colony-based wireless sensor networks routing algorithm

针对无线传感器节点能量、通信能力及计算能力有限等特点,将蚁群算法应用于无线传感器网络,提出一种改进的蚁群路由算法,考虑了节点的能量、距离、通信半径和传输方向等参数.实验结果表明:该算法有效地减少了网络能量消耗、节点死亡数、路由跳数和数据传输的路径长度,延长了无线传感器网络的寿命,实现无线传感器网络在通信过程中快速、节能的路由。

Aimed at the feature of wireless sensor networks （WSNs） nodes, such as energy-constrained, limited communications capability and lower computing power and so on. Ant colony algorithm is applied to WSNs. A novel routing algorithm of WSNs which is based on ant colony algorithm is presented. The energy of nodes, distance, radius of communication and transmission direction and other parameters is taken into account. Research results show that this routing algorithm can reduce energy consumption ,the dead number of nodes, routing hops and the length of data transmission path. As a result of prolonging the life of wireless sensor networks and making the WSNs fast and energy-efficient in the communication process.
