Three routing algorithms for publish/subscribe system in mobile Ad Hoc networks
发布订阅系统在移动Ad Hoc网络中的三种路由算法

Routing algorithms is a key issue in large-scale publish/subscribe system under Ad Hoc network. The protocol of publish/subscribe system was introduced. Three content-based routing algorithms of publish/subscribe system in mobile Ad Hoc networks were proposed. Their performances were evaluated by network simulations. The results show that RAFT-CBR provides both fault-tolerance and reliability, and it can guarantee 100% information delivery at the expense of transmission delay; CBR, with low delay, is more suitable for distributed publish/subscribe protocol in wired networks at the expense of reliability; FT-CBR, with low delay, extends CBR to provide fault-tolerance.
