摘　　要：为提高WSNs中跨层设计的网络性能,针对WSNs和跨层设计的特点,从WSNs实际可观察参数角度出发,提出了一种符合WSNs实际应用需求的三层QoS指标体系,并对各层QoS指标进行规范化描述。由于该指标体系所选取的指标都是实际应用中可直接检测到的网络性能参数,使得实施QoS保障的可操作性得到了增强。考虑到WSNs中跨层QoS保障的实施,设计出一种跨层的QoS体系结构,并对QoS提供和QoS维护的问题进行了详细分析。指出了下一步的研究工作。To improve the network performance of cross-layer design in WSNs,according to the characteristics of WSNs and cross-layer design,from the perspective of actual observed parameters in WSNs,a three-tier of QoS metrics system comforing with the actual application requirements of WSNs was presented,and a kind of standardized description of each layer QoS metrics was given.Because the selected indicators of index system come from network performance parameters and they could be detected directly in practical application,the implementation of QoS guarantee operability is feasible.Considering the implementation of the cross-layer QoS guarantee in WSNs,a cross-layer QoS architecture was designed,and detailed analysis on provision and maintenance of QoS.Moreover,the future research work was pointed out.
