摘要/Abstract

摘要： 为了解决认知Ad Hoc网络中节点和链接失效问题,提出一种基于主从机制的认知Ad Hoc网络可靠路由构造方法MSMRC。该协议考虑了网络中主用户活动规律,引入链路可靠时长和信道可靠时长的度量来设计主路由和备份路由。当现有路由失效时,通过预先构造的备份路由快速恢复认知用户之间的通信。实验表明,MSMRC协议能够显著降低平均路由开销,而且可以提高网络的数据包投递率和链路修复率,保证了网络端到端通信的服务质量。

Abstract: To solve the node and link failures in cognitive radio Ad Hoc networks,a novel master and slave mechanism based route,named MSMRC,for reliable communication between cognitive users was presented in this paper.The route takes the primary user activity patterns into account,and both the link reliable time and channel reliable time are also introduced to design this routing mechanism.When some routes fail,the existing communications between the cognitive users can be restored quickly through pre-configured slave routes.Experiments show that the proposed MSMRC method can significantly reduce the average overhead,and improve the packet delivery ratio and link repair rate,ensuring the quality of the network end to end communication services.
