摘要: 无线Mesh网络是一种多跳分布式自组织网络。提出了一种IEEE 802.16 Mesh模式下的分布式QoS保障调度算法。该算法充分利用方向性天线带来的空分复用增益,并采用DiffServ机制保证QoS需求。仿真结果表明,所提算法不仅提高吞吐量,而且能够为不同类型的服务提供QoS保障。

Abstract: Wireless Mesh network is a multi-hop distributed self-organizing network.This paper presents a scheduling scheme for distributed QoS guarantee for IEEE 802.16 in Mesh mode.This algorithm makes full use of directional antenna to bring the spatial multiplexing gain,combining with DiffServ mechanism to ensure the QoS requirement.Experimental results through simulations show that the proposed algorithm not only improves the throughput,but also can provide QoS guarantee for different types of service.
