Joint Cooperative Routing and ChanneI Assign ment in Mu Iti-radio WireIess Mesh Network
摘要
Abstract
The existing cooperative routing algorithms ignored channel assignment issue in multi-radio wireless mess network.To provide high performance service for concurrent flows,this paper combined both multi-radio multi-channel tech-nique and cooperative communication technique to reduce co-channel interference and obtain cooperative diversity gain. Based on virtualized representation method for the cooperative communication module,this paper simplified the problem of joint cooperative routing and channel assignment to the problem of joint direct routing and channel assignment,and modeled the problem as a mixed integer linear programming,and proved it NP hard.In order to solve the problem,this paper further proposed a loose joint cooperative routing and channel assignment algorithm (L-JCRCA).The simulation results show that L-JCRCA can promote network throughput effectively.关键词
