一种提高WiMax mesh网络吞吐量的方案

Throughput enhancement in WiMax mesh networks

文章针对IEEE802.16标准未指定空间资源管理方案,提出一种提高WiMax mesh网络吞吐量的方案,包括接入过程中公平的路由树构建算法和调度过程中并发传输算法;对节点接入和集中调度过程进行仿真,比较了不同的路由树算法在并发传输算法下的性能。仿真结果显示,提出的路由树构建算法显著提高了端到端的吞吐量,验证了方案的有效性。

IEEE802. 16 standard does not specify spatial resource management in the protocol. To increase spatial reuse, a throughput enhancement scheme is proposed, including a fair route construc- tion algorithm for access and a general concurrent transmission algorithm for scheduling. In simula- tion of access and scheduling, the performance of the general concurrent algorithm with different routing trees is compared, which shows that total throughput is significantly improved when using the presented construction algorithm for concurrency.
