传统的单目标路由协议很难完全满足Ad hoc网络业务量增加的需求.多目标路由协议在传输过程中可以构建最佳的多目标路由树,链路带宽消耗较小,节点的处理较少,分组交付时延较短,从而降低了通信开销.对Adhoc网络中的典型多目标路由协议MAODV和ODMRP协议进行性能分析,并用仿真工具NS2对它们进行仿真.仿真结果表明:多目标路由协议只有采用更加合理的算法和策略才能使其更稳定和更高效.
The traditional single objective routing protocol is difficult to fully meet the increasing traffic demand in Ad hoc network. Multi destination routing protocols can construct multi objective optimal routing trees in the transmission process, it's link bandwidth consumption is smaller,it's node needs little processing, it's packet delivery delay is short, and it's communication overhead is reduced. The performance of typical multi-destination routing protocols MAODV and ODMRP are analyzed, and then protocols are simulated by network simulation software NS2. We find that multi-destination routing proto- col can be more stable and efficient only by use of more reasonable algorithm and strategy.
