摘要: 提出了一种基于覆盖的环簇路由算法CRAC。该算法利用Sink节点以广播环域坐标的方式将网络分为若干环域,并根据应用需求的服务质量计算各环域的覆盖划分以确定轮换簇,各轮换簇交替休眠以降低网络能耗。网络各环域根据能耗均衡方程确定其是否为发送环,将采集的数据并行传送到传输路径后汇聚至发送环,再由LEADER节点发送至Sink节点。仿真实验结果表明,该算法大幅度降低了网络的通信时延和能耗,延长了网络的生存时间,使节点能量均衡下降。

Abstract: To improve the performance of Wireless Sensor Network (WSN), a concentric ring cluster routing algorithm based on coverage (CRAC) is proposed. This algorithm divides the WSN into rings using the coordinate of concentric ring by Sink. Meanwhile, it works out the coverage partitions of every ring and the rotational clusters according to QoS of application requirements. Different sensor nodes of the rotational clusters in the same ring can alternate into sleep mode to save energy. By judging the energy equilibrium equation, each ring can decide itself whether to be the sending ring. The data gathered is collected to the sending ring after it is in parallel transmitted to the path of transmission. Then, the data is sent to Sink node by LEADER node. Simulation results show that the proposed CRAC can greatly reduce both delay time and energy dissipation, prolong network lifetime and make the network energy bourn evenly.

Key words: computer application, wireless sensor networks(WSN), rotational cluster, coordinate of concentric ring, energy equilibrium equation, delay time, network lifetime
