摘要 针对无线传感器网络保证服务质量的路由问题,提出一种区分服务和优先级保证的无线传感网跨层节能算法,该算法对网络服务分级,在蚁群算法的路径选择时综合考虑节点的剩余能量、负载和节点位置信息,同时选择切换概率小的信道。仿真实验表明,该算法在保证服务质量的前提下,增加了路由的有效性和鲁棒性,降低并均衡各节点能耗,时延、网络生存周期等指标均体现较好性能。 For the routing problems of guaranteeing QoS in Wireless Sensor Network(WSN),an energy saving cross-layer routing algorithm based on differentiated services and priority is put forward,in which the services are classified and then the residual energy,load and position of nodes are taken into account for path selection of ant colony algorithm.At same time,the channel with a lower switching probability is chosen.Simulation results show that the algorithm can improve the robustness of routing,reduce and balance energy consumption and is with optimal features such as low delay and long network lifespan under the conditions of premised guaranteed QoS.
