摘　　要：提出了一种基于广播坐标的无线传感器网络静态链簇路由算法SCTC。该算法在节点地理信息未知的情况下,利用双基站把网络划分为若干静态簇以降低网络动态成簇的能耗,采用簇内成链及簇间并行通信的方式减少簇内通信的能量损耗并降低传输时延,以轮换汇聚层的方法均衡节点能量消耗。仿真实验结果表明,该算法可以大幅度降低网络的能耗并延长网络的生存时间,降低了网络通信的时延。A static chain-cluster routing protocol, SCTC, based on transmitting coordinate for wireless sensor network is proposed. Without location information of nodes, the protocol utilizes double base station to make networks into static clusters to reduce energy dissipation in dynamic clustering. It links the in-cluster nodes into a chain to decrease energy dissipation in in-cluster communication. The protocol reduces time delay by realizing parallel communication among the nodes in every cluster. It balances the energy consumption among the sensors in the network by rotating the collective layer. Simulation results show that SCTC can not only achieve reduction in energy dissipation and latency, but also can make the energy of the network burn evenly and thus improve the energy efficiency and lifetime of the networks.
