MIMO多跳无线网络分布式链路调度算法

Distributed Link Scheduling Algorithm of MIMO Multi-hop Wireless Network

针对MIMO多跳无线网络分布式链路调度相关研究缺乏的现状及现存算法吞吐量性能差的问题,提出了基于MIMO-pipe模型的MDLS(MIMO based Distribute Link Schedule)算法。算法首先利用MIMO-pipe模型的链路共存约束对链路集合进行预处理,缩小参与调度的链路范围;然后通过构造决策调度集合找到传输调度集合进行MDLS算法。理论分析证明了MDLS算法的正确性,仿真实验表明该算法的网络吞吐量性能优于现存同类算法。

Aiming at the lack of related research on the distributed link scheduling of MIMO multi-hop wireless networks and the poor throughput performance of existing algorithms, an MDLS （MIMO based Distribute Link Schedule） algorithm based on MIMO-pipe model is proposed. Firstly, the link coexistence constraint of the MIMO-pipe model is used to preprocess the link set, and the link range of the scheduling is reduced. The MDLS algorithm is then executed by constructing a decision set to find the transport scheduling set. Theoretical analysis proves the correctness of the MDLS algorithm. Simulation results show that the proposed algorithm has better throughput performance than the existing algorithm.
