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

Broadband Wireless Metropolitan Area Network (MAN) is a booming branch in the area of wireless communication. The de-sign 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 con- trol, 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.
