摘　　要：针对无线传感器网络中分簇多跳通信方式产生的能量负载不均衡问题,提出一种能量均衡的动态间隔分层路由协议(EHRD)。它通过层次间隔动态调整算法动态调整层次间隔,使得层次的能量消耗不均匀状况得到缓解,从而达到整个网络能量负载均衡。用NS2仿真测试结果显示:能量均衡的动态间隔分层路由协议在网络能量负载、网络生存时间、缓解网络"热区"问题上有所提高。In wireless sensor networks, clustering algorithm used multi-hop communication which generated energy-unba- lanced issues. This paper presented a new energy-balanced hierarchical routing protocol with dynamic intervals. It adopted the intervals of hierarchical of dynamic adjustment algorithm which could adjust the hierarchical intervals to balance the energy of different zones. In this way, it achieved energy-balanced in wireless sensor networks. According to NS2 simulation results show the protocol makes the energy-balanced more better and improves the living time of network and weakens the ＂hot zone＂issues.
