ODMRP组播协议非常适合于带宽限制大、移动性强和节点能量受限的Ad hoc网络。为了进一步提高该协议的性能,文中提出一种新的技术来增强其功效。增强ODMRP的主要目标有:(1)改进节点移动模式的适应性;(2)消除路由获得时延。最后仿真结果显示该改进协议比原协议在数据分发率和网络有效性等性能方面有很大改善。
The ODMRP multicast protocol is ideally suited for Ad hoc networks with large bandwidth constraints, high mobility, and limited node energy. In order to further improve the performance of this protocol, a new technique is proposed to enhance its effectiveness. The main objectives of enhancing ODMRP are: (1) to improve the adaptability of node mobility mode; (2) to eliminate the routing delay. Finally, the simulation results show that the improved protocol has a great improvement over the original protocol in terms of performance such as data distribution rate and network availability.
