摘要
为提高移动Ad Hoc网中AODV路由算法的性能,文章采用跨层协同设计的思路对它的HELLO消息机制进行改进,提出一种新的路由算法:CLAODV.在不影响功能的前提下,此算法调整了HELLO消息的控制层面,从网络层控制改为MAC层控制,缩减了HELLO消息的数量和内容.性能分析和仿真结果表明:与经典的AODV算法相比,CLAODV减少了开销,提高了效率,使吞吐率、时延和成功率等性能得到综合提升.
To improve the performance of AODV routing algorithm in mobile Ad Hoc networks, the authors adopt the cross-layer method to improve its HELLO message mechanism and present a novel routing algorithm: CLAODV. The algorithm not only changes the controller of HELLO messages from network layers to the MAC layers, but also reduces the quantity and size of HELLO messages. From performance analysis and simulation results, it can be found that CLAODV has many advantages. Compared to the classic AODV algorithm, CLAODV reduces the overhead, improves the efficiency and other performances, such as the throughput, the endto-end delay and the success ratio.
