摘　　要：针对无线传感器网络内节点能量受限的特性,提出一种基于访问控制的链式分层路由协议LHRPAC(Linked Hierarchical Routing Protocol Based on Access Control)。该协议考虑了节点的能量和相对度这2个因素,从簇头选择、建链过程、节点间通信模式等角度对PEGASIS协议进行改进,在访问控制技术的基础上进行数据融合检测。仿真结果表明,LHRPAC可有效地提高实时数据传输,延长整体网络的生命周期。The paper first discusses the characteristic of comparatively limited energy supply of nodes in Wireless Sensor Networks（ WSN）,and then proposes a Linked Hierarchical Routing Protocol based on Access Control（ LHRPAC）. Took relative adjacent degree and energy into consideration,optimization is made on cluster head election,linking and communication,and data fusion detection based on access control is carried out. The simulation results indicate that LHRPAC produces significant reduction of time delay when transmitting across the network,and subsequently,prolongs the whole network lifetime.
