【摘要】 随着移动通信技术的发展和基于网络的应用服务的激增,能够快速定位网络中服务资源的服务发现系统成为了网络中不可缺少的重要模块。在移动自组织网络里,采用群集可以使网络资源得到更有效地利用。文章归类分析了现有的一些服务发现协议,研究了基于群集的MANET服务发现,并在此基础上提出了一种分布式服务发现模型。在模型中,群头之间以对等方式形成虚拟骨干。仿真结果表明,该模型实现了可扩展的服务发现。更多还原

【Abstract】 With the development of mobile communications technologies and the growing popularity of network-based services,service discovery has been the necessity functions for quickly locating resources in the networks.Clustering promotes a more efficient use of resources in Mobile Ad hoc NETwork(MANET).This paper is classified some existing service discovery protocols and researched cluster-based service discovery in MANET.Based on cluster,we proposed a decentralized service discovery model.In this model,clusterheads form a virtual backbone in peer-to-peer.Simulation results indicate that,a scalable service discovery is solved.更多还原
