Cooperative routing in multi-hop multi-radio wireless network
摘要
Abstract
Cooperative communication for wireless networks has gained a lot of recent interests due to its ability to mitigate fading with exploration of spatial diversity. This paper studies the optimization problem of jointing routing and cooperative relay selection in multi-flow multi-radio cooperative wireless network, and model the problem of maximizing the minimum transmission rate of multiple flows as a mixed-integer linear programming problem. To solve this problem, a heuristic joint flow routing and relay node assignment algorithm based on branch-bound(JFRBB)is proposed. JFRBB is an iterative algorithm, it achieves the optimal solution by decomposing the original problem into several sub-problems based branch-bound method. The simulation results demonstrate that, compared with the performance achieved in multi-radio non-cooperative network and single radio cooperative network, JFRBB can make the multi-radio cooperative achieve much better performance of rate gain, and aggregate traffic.关键词
