摘　　要：在无线医疗传感器网络体系结构中,由于信息的采集是由大量医疗传感器节点合作完成的,因此采用分簇路由协议能够有效减少节点能量的消耗和方便节点的拓扑管理。在相关研究的基础上提出一种新的动态分簇协议WMDCP(dynamical clustering protocol in wireless medical sensor networks),以解决目前分簇协议中缺少对医疗传感器节点动态分布的支持问题。仿真实验表明,相对其它分簇协议,WMDCP不仅可以有效地改善无线传感器网络的性能,而且可以有效延长网络中传感器节点的生存时间。In the wireless medical sensor network architecture, because sensed data were collected co-operatively by a large number of medical sensor nodes. To the effect, adopting the clustering protocol can effectively reduce nodes＇ energy consumption and facilitate the management of the topology. Based on related works a new dynamic clustering protocol, WMDCP（energy-efficient dynamical clustering protocol in wireless medical sensor networks） was proposed, so as to solve the issue of lacking the support for dynamic distribution of medical sensors in the present clustering protocols. Compared with the existing clustering protocols, the simulation results shows WMDCP protocol can efficiently improve network performance and prolong the lifetime of sensors in network.
