摘要
针对ODMRP协议在拓扑频繁变化的移动自组网中存在的不足,提出一种贪婪稳定路由协议GS-ODMRP,通过贪婪转发机制建立主路径,每条链路的备用路径基于链路保持连接时间建立,从而提高协议的鲁棒性.仿真结果表明,相比ODMRP协议,GS-ODMRP协议提高了分组传输成功率,并且降低了网络开销和传输时延.
Aiming at the shortage of ODMRP in mobile ad hoc networks where the topology changes frequently,a greedy-based stable routing protocol called GS-ODMRP is proposed,in which the primary path is constructed based on a greedy forwarding mechanism,and the backup path for each link is established according to the link lifetime to enhance the robustness.Simulation results demonstrate that the GS-ODMRP not only improves the packet delivery ratio but reduces the control overhead and end-to-end delay.
