ARDCH:适于多媒体传感器网络的自适应周期分簇机制
摘要
分析了多媒体传感器网络节点部署特点以及多媒体信息位置相关性特点
提出了一种基于剩余能量与传输距离的自适应周期簇头竞争机制(ARDCH
adaptive round distributed cluster head)
综合考虑通信代价及剩余能量选取簇头
同时根据剩余能量来动态调节簇头的工作周期
以此均衡网络中节点的能量消耗。此外采用多信道簇间通信
避免簇间干扰
与已有的几个分簇协议相比
显著地延长了网络的生存周期
更适于多媒体传感器网络。
Abstract
The node deployment and location-related multimedia data in WMSN were analyzed.Based on the energy ef-ficiency and communication range
an adaptive round distributed cluster head(ARDCH) scheme was proposed.To bal-ance the energy consumption of nodes in WMSN
the cluster headers were selected according to the communication cost and the remaining energy
and the work round of cluster headers were adjusted dynamically by the remaining energy.The multi-channel communication between different clusters was employed in ARDCH to avoid inter-cluster interference.By comparison with other clustering protocols
the simulation results show that ARDCH is more appropriate for WMSN and prolong the life cycle of network.
