摘要
无线传感器网络(WSN)中的LEACH-C路由协议性能严重依赖于基站位置,为此提出一种融合了多跳路由和智能休眠机制的改进型LEACH-C协议(LEACH-CMS).首先,利用LEACH-C协议选择簇头,并构建分簇结构;然后,通过蚁群算法(ACO)在考虑路由距离和簇头能量下,寻找簇头到基站的最优多跳路径,并传输数据到基站;最后,基站根据传输数据的质量,利用休眠机制使不重要地区的节点休眠,以此节约能耗.实验结果表明,LEACH-CMS比LEACH-C协议提高约35%的网络寿命和20%的延迟性能.
The performance of LEACH-C routing protocol in wireless sensor networks （WSN） is heavily dependent on the location of the base station. In order to solve the problem,a improved LEACH-C protocol （LEACH-CMS） is proposed,which combines multi hop routing and intelligent sleep mechanism. First,the LEACH-C protocol is used to select the cluster head,and construct the cluster structure; then, use the ant colony optimization （ACO） to find optimal multi hop paths of cluster head to the base station in the consideration of the routing distance and energy of the cluster head, and transmit data to the base station. Finally,the base station uses the sleep mechanism to make it less important region of the node sleep according to the quality of the transmission data, in order to save energy consumption. The experimental results show that the LEACH-CMS protocol improves the 35% network lifetime of and the 20% delay performance compared to the LEACH-C protocol.
