| 摘 要： | 路径压缩技术是一种有效的应用于移动Ad Hoc网络的按需路由优化技术。但目前已有的路径压缩技术尚存在压缩盲目、路径不稳定、短暂缩减和多次缩减现象频繁等不足。通过建立动态路径压缩模型得出概率意义上、实时动态化的路由稳定期,提出一种基于动态压缩模型的路径压缩技术DMPCT.DMPCT有效抑制了路径压缩的盲目性,在控制短暂缩减和多次缩减,提高路径稳定性等方面有显著提高。仿真表明,DMPCT在与AODV和PCA的性能比较中具有低原始RREQ数、低控制负载、低端到端时延和高包发送率等特点,是一种高效、稳定的移动Ad Hoc网络路径压缩技术。

| Abstract: | The path compression techniques are efficient demand routing optimizing technique for mobile Ad Hoc networks.However,the current path compression techniques have some shortages,such as blindness for compression,unstable path,frequent ephemeral short-cuts and multiple short-cuts etc.This paper establishes a dynamic path compression model and calculates the dynamic,real-time stable compression period in probability sense.A dynamic model-based path compression technique(DMPCT) is proposed,which can restrain th... |
