摘要
针对无线传感器网络的节能以及能耗均衡问题,本文提出了一种无线传感器网络混合路由网络模型,将平面路由和层次路由有机地结合在一起,在数据获取阶段采用层次路由,而在数据传输过程中使用平面路由。同时,论文提出了一种基于该模型的动态成簇自适应路由算法HDAR(Hybrid Dynamic Adaptive Routing algorithm)。在算法中设计了基于现场数据的动态成簇机制来完成数据的收集,使用自适应的路由选择算法将数据传输回Sink节点。仿真结果表明HDAR协议在节能和能耗均衡方面达到了良好的效果。
In this paper, a hybrid routing sensor network model is proposed which combines plane routing and hierarchical routing seamlessly. Hierarchical routing is adopted in data acquiring stage while plane routing is used in data transmission stage. A new hybrid dynamic adaptive routing (HDAR) algorithm is proposed, based on the hybrid network model. HDRA utilizes a dynamic clustering scheme to complete data gathering and the aggregated data is relayed to the sink node through paths generated by adaptive route selection algorithm. Simulation results show that HDRA is able to save energy, as well as balance energy dissipation evenly throughout the sensors.
