中文摘要：
针对分层无线传感器网络的簇首节点容易成为网络瓶颈制约网络性能的不足，提出一种低能耗的路由协议。采用多汇聚（Sink）节点模式来构建网络，利用RSSI（接收信号强度指示）测出各传感器节点与各Sink节点之间的距离，并依据距离的远近为Sink节点划分作用域。通过传感器节点单向与所属Sink节点通信来降低簇首节点的负担。仿真实验结果表明提出的路由协议能有效克服簇首节点网络瓶颈问题，从而降低网络能耗，提高网络生存时间，对于无线传感器网络应用于大范围数据收集的网络具有重要的价值。
英文摘要：
Aimed at the weak point of the cluster head node of hierarchical wireless sensor network is easy to become anetwork bottleneck and restricted the network performance,this paper proposes an energy-efficient routing protocol.Thispaper constructs network by using multiple sink nodes and the RSSI(Received Signal Strength Indicator)to get the distancebetween the normal nodes and sink nodes,then divides the scope for each sink node by this distance,and uses themethod of the sensor node and its sink node one-way communication to reduce the burden of cluster head node.The simulationresults show the proposed routing protocol can effectively overcome the network bottleneck in cluster head,so as toreduce the energy consumption and improve the network lifetime,and this protocol has important value to that wirelesssensor network applying large-scale data acquisition networks.
