摘　　要：为了有效均衡无线传感器网络能耗、缓解能量洞问题、延长网络生命周期,提出了一种节能高效的非均匀分簇路由协议,其核心思想是采用结合计时广播和簇头轮换机制的非均匀分簇(BR-EEUC)算法对网络分簇,并根据代价函数选择代价较低的簇头作为中继节点,形成以汇聚节点为根节点的多跳路由,从而大大降低了能量开销。通过在OMNet++平台上的仿真实验结果表明:与LEACH和EEUC等路由协议相比,该协议有效地均衡了网络能量消耗,延长了网络寿命。In order to effectively balance energy consumption of nodes and to relieve energy-hole problem and prolong network life cycle in wireless sensor networks （ WSNs ） , a new energy-efficient uneven clustering routing protocol for WSNs is proposed. The core idea of the protocol is using an uneven clustering algorithm--BR-EEUC which combines with timing broadcast and cluster head rotation mechanism to clustering network, and according to cost function to choose a less costly cluster head as relay node, to form multi-hop routing in which sink node is used as root node, so energy cost is greatly reduced. The simulation experiment result on OMNet ＋ ＋ shows that, compared with LEACH and EEUC, BR-EEUC protocol effectively balance network energy consumption, and extend network lifetime.
