d-hoc网络中发布订阅系统路由策略设计与仿真
esign and Simulation for Routing Strategy of Publish/Subscribe System in Ad-hoc Networks
发布订阅是网络通信范型之一，具有异步和多点通信等特点，在时间、空间和控制流上完全解耦，非常适合应用于Ad-hoc等分布式网络。本文设计了一种Ad-hoc网络中发布订阅系统按需路由策略(PSODR)；结合Ad-hoc网络AODV协议，在网络仿真平台NS2上模拟实现洪泛策略和PSODR策略；与洪泛策略相比，PSODR策略减少了网络中的洪泛数据量，同时保证了发布订阅系统的实时性和可靠性。
Publish/subscribe which is one of communication models has characteristics of asynchronous and multipoints communication, and it decouples in time, space, and control flow; so it is appropriate to Ad-hoc networks. In this paper, Publish Subscribe On-Demand Routing (PSODR) strategy for Ad-hoc networks is designed. By combining AODV protocol as routing layer protocol, Flooding strategy and PSODR strategy are simulated in NS2. PSODR strategy is effective in decreasing redundant flooding data, and at the same time, it guarantee the real-time and reliability of publish/subscribe system.
