摘　　要： 为了解决SCAMP协议因节点之间随机连接,节点的查找算法在高度动态的网络中效率不高的问题,提出了一种改进的SCAMP协议——Ex-SCAMP。开发了Ex-SCAMP协议的加入和退出算法,设计了孤岛节点修复机制。由于Ex-SCAMP协议的节点只需具有局部信息就能构建全局随机图,故其邻居列表和泛洪跳数都较小。实验结果表明,与SCAMP协议相比,该协议具有实现简单、可扩展性好和容错性高等特点。 To solve the low efficiency of the node location algorithm defined by SCAMP （scalable membership protocol） in dynamic network because of nodes connected by random method, an improved SCAMP named Ex-SCAMP was proposed. The algorithms for joining and exiting were developed, and the repair mechanism for isolated node designed. In addition, the nodes with local knowledge in Ex-SCAMP can build global random graph, so the neighbor table size and flooding hops are low. Experimental results show that the Ex-SCAMP has the features of simple implementation, good scalability and high fault tolerance compared with SCAMP.
