摘要
基于运动预测选择最稳定的路径,讨论路由修理问题,并使用马尔可夫链模型分析了路径的可用度和路径寿命.分析结果表明,与非可修选路策略相比,带有本地可修选路的策略优化了路径可用度,延长了路径寿命,降低了控制开销.仿真结果表明,该协议具有较高的分组递交率和较低的控制开销.
The most stable path is selected based on mobility prediction, and the route repair mechanism is discussed. Markov-chain based analysis is used for analytical modeling of the path availability and the time interval between successive route discoveries. Analytical results show that, compared with non-repairable routing strategy, the routing protocol with local repair optimizes the path availability, prolongs the lifetime of path, and reduces the control overhead. Simulation results show that the protocol has high packet delivery ratio with low control overhead.
