针对Ad hoc网络中基于缓存的路由修复机制进行研究.通过对基于缓存的路由修复机制进行数学建模和理论分析,得出了基于缓存的路由修复机制的最优缓存策略应具有如下三个性质:1)优先缓存寿命长的可用路径;2)优先探测寿命长的可用路径;3)对于每次路由发现的可用路径集合.基于这些关键性质,本文设计一个最优缓存算法,并通过ns-2仿真验证了本文设计的最优化缓存策略和最优缓存算法的正确性和有效性.
Aiming at the research of cache-based routing repair mechanism in Ad hoc networks, the optimal cache strategy of cache-based routing repair mechanism is derived from the mathematical modeling and theoretical analysis of the cache-based routing repair mechanism, which has the following three properties : 1) available cache with long service life, 2) preemptively available paths with long service life, 3) set of available paths for each route discovery, and based on these key features, an optimal cache algorithm is designed and optimized by ns- Simulation results show that the optimal caching strategy and optimal caching algorithm designed in this paper are correct and effective.
