Abstract

Abstract: To reduce rerouting operation and enhance the network performance in Mobile Ad hoc Network（MANET），an entropy-based QoS routing algorithm with directed flooding is proposed.The directed flooding mechanism is used to control the range of route request and reduce the control overload.The entropy metric is adopted to select the stable route and reduce the routing reconstructing.The algorithm with OPNET is simulated and the results show that the proposed algorithm can acquire a high data packet delivery ratio with low control overhead by selecting the stable routing path.

摘要： 为了减少移动自组网中路由频繁失效和重构，提高网络性能和资源利用率，提出了基于熵的定向洪泛QoS路由算法。该算法利用定向洪泛的机制控制路由请求转发范围，降低网络的控制开销；并采用一种度量方法——熵来选择稳定的路由，减少重路由，提高数据成功传输率。利用OPNET对算法进行仿真，结果表明该算法能以较小控制开销获得较好的数据传输，降低了路由重构的概率，适合移动自组网的高度动态的特点。
