无线城域网综合资源调度策略设计与实现

宽带无线城域网是当今无线通信领域中的一个热点，而其中的资源调度策略直接关系到
系统性能的优劣。本文针对IEEE802.16 标准下的宽带无线接入系统设计了一套能够保证用户QoS 的资源调度和分配方案，该方案由接纳控制方案、请求机会分配方案及带宽分配方案三部分组成，它的双层调度机制能够针对不同QoS 等级的业务提供不同的调度方案，满足用户的QoS 要求。

The Design and Realization of an Integrated Resource Scheduling Scheme for WMAN
(Tsinghua University wireless and mobile communication technology research center) Zhang Jin, Su Xin Abstract Broadband Wireless Metropolitan Area Network (MAN) is a booming branch in the area of wireless communication. The design of the resource allocation and scheduling scheme of the system is in close relation with the whole system performance. A novel resource allocation scheme which can guarantee the QoS is proposed in this paper. The scheme includes the connection access control, the bandwidth request timeslot allocation and data bandwidth allocation. The two-layer scheduling architecture of the scheme can provide different scheduling strategy for services with various QoS grade to guarantee their QoS.
