摘要：

提出一种基于等级的无线体域网（WBAN）QoS 框架，将 WBAN 中的 QoS 分为3个等级。利用 IEEE 802.15.4的信标模式中基于时隙的CSMA/CA机制、保障时隙以及传感器节点内部的流量区分实现了QoS框架。仿真结果表明提出的QoS框架可以满足WBAN对QoS的需求。

Abstract:

A quality of service framework based on grade for WBAN that have three different grades was proposed. Utilizing time slot-based CSMA/CA of beacon enabled model of IEEE 802.15.4, guaranteed time slot and traffic differentiation,the QoS framework was implemented. Simulation results indicate the QoS framework can meet the QoS requirements of WBAN.

Key words: wireless body area network, quality of service, guaranteed time slot scheduling, backoff exponent
