移动自组网中基于内容的发布/订阅路由协议

Publish/Subscribe Routing Protocol Based on Content in Mobile Ad Hoc Network

移动AdHoc网络下的分布式应用开发面临较大挑战,因此引入基于内容的发布/订阅中间件具有重要意义。该文提出一种新的基于内容的路由协议。通过建立优化的动态组播格网,根据内容匹配的结果,只向匹配的订阅节点传播事件,而限制不必要的事件传播。实验结果表明,该协议能够较大地改善网络总代价,节省网络带宽,提高系统的扩展性和性能。

The development of distributed application in Mobile Ad Hoc network（MANET） faces many challenges, so it is important to introduce content-based publish/subscribe middleware in it. This paper proposes a novel content-based routing protocol. It constructs an optimized dynamic dissemination mesh and propagates events only to the matched subscription nodes. Unnecessary propagation of events is confined. Experimental results show that the protocol decreases the total cost of the network and saves network bandwidth largely, which boosts the scalability and performance of the system.
