移动Ad Hoc网络多信道多径路由的优化与仿真研究
|
摘要
由于现有多信道多径路由协议不能有效均衡信道与路径负载,所以在高负载MANET环境下网络性能较差。提出一种基于信道切换的多信道多径路由优化算法,该算法对不同类型分组进行自适应信道调度,通过限制网络控制报文的泛洪规模与动态切换数据报文的发送信道等策略,有效提高网络对信道与路径的综合利用。为了实现路由对信道切换,对NS-2进行可切换多信道拓展,仿真结果表明该算法能有效提高高负载MANET的性能,在丢包率、时延、吞吐量等方面均明显优于传统多信道多径路由。
The existing multi-channel multipath routing protocol cannot effectively balance the load under paths and channels,so in high load conditions,the comprehensive performance of MANET is poor. A multi-channel assignment and multipath routing algorithms is applied,which based on the traditional multi-channel multipath routing. The improved algorithm carries out the adaptive channel scheduling policy for different message,limits the network control message flooding,and dynamically allocates data to multi-channel to realize the load balance,and effectively take advantage of multipath and multi-channel. In order to achieve the channel switching in the routing protocol,an expanding model of NS2 is applyed. The simulation results show that the improved algorithm can effectively improve the performance in the MANET of high load,which is significantly superior to the traditional multichannel multipath routing in the packet loss rate,delay,and throughput.
