Ant Colony Routing Protocol Based on Opportunity Strategy for Wireless Sensor Networks

针对无线传感器网络节点能量受限的局限性,以设计高能效路由协议为目标,提出了一种基于机会策略的蚁群分簇路由协议。在分簇算法中引入能量估计的概念,优化网络分簇;融合能量等级及路由跳数,改进蚁群多跳路由的信息素更新规则,设计机会路由策略,降低额外网络控制开销。仿真实验结果表明,基于机会策略的蚁群路由协议能够提高网络使用效率,均衡节点能量消耗,从而延长网络的生命周期。

Aiming at the limitation of energy limitation of wireless sensor network nodes,an ant colony routing protocol is proposed based on opportunity strategy for wireless sensor networks( OACR) to design the energy-efficient routing protocol. OACR adopts an estimating energy-based clustering algorithm to optimize the number of clusters.The pheromone updating rule of ant colony multi hop routing is improved by combining energy level and route hops.The opportunistic routing strategy is designed to reduce the additional network control overhead. The simulation results show that the ant colony routing protocol based on opportunistic strategy can improve the network efficiency,balance the energy consumption of nodes,so as to prolong the life cycle of the network.
