摘要
以仿真为主要手段研究了自组织网中基于AODV的路由算法的性能 ,比较了采用全网泛洪方式和限制泛洪半径方式下的网络性能。改进了现有调度策略 ,并仿真了其对端到端时延的影响。仿真结果表明 ,采用限制泛洪半径方式的网络性能明显好于全网泛洪方式 。
By simulation ,this paper studies the performance of routing algorithms based on AODV in Ad Hoc network is studied.A comparison in network performance between using whole-network flooding mode and using flooding-radius-limited mode is made.Also, the influence of an improved schedule strategy on the end-to-end delay is simulated. Simulation results show that the network performance is obviously better by using whole-network flooding mode than by flooding-radius-limited mode and the improved schedule strategy can further improve the network performance.
