MHWSN中保证混合业务QoS的跨层调度算法

针对中高速传感器网络中混合业务QoS（Quality of Service）要求，跨层考虑物理层和数据链路层参数，提出了一种保证混合业务服务质量的调度算法AM-LWDF。该算法同时考虑时延优先级和吞吐量优先级，在满足实时业务QoS约束的前提下，以最大化系统吞吐量为目标建立了相应的优化模型，对实时业务能够满足时延较小的要求，对非实时业务满足吞吐量较大的要求。仿真结果表明，该调度算法可以灵活地在时延和吞吐量之间取得满意的折衷，并保证不同类型业务用户间的公平性。

Cross-layer scheduling algorithm with guaranteed diverse QoS in MHWSN

To efficiently support the diverse Quality of Service（QoS） of hybrid service in middle and high rate sensor networks（MHWSN）.A scheduling algorithm named AM-LWDF based on cross-layer optimization is proposed with guaranteed divers QoS in this paper.A mathematical formulation is provided with the goal of maximizing throughput under real-time service QoS constraints considering both the delay priority and throughput priority.It guarantees smaller delay in real-time service and larger throughput in non real-time service.Simulations show that the scheme can achieve compromise between delay and throughput flexibly and guarantee fairness among different user.
