关于WSNs中QoS的研究以前都是孤立的,或是特定在某些功能层上的研究,或是特别指定某些应用场景的研究。而论文根据WSNs的参考体系结构,分层讨论了QoS需求的定义以及低层QoS需求对高层QoS需求的影响,从而得出一个整体的QoS框架,然后根据各个QoS需求之间的关系,分析它们之间是否有权衡点以及怎样找到这种权衡关系,以便深入理解WSNs中各QoS需求的互相作用。当无线传感器网络中存在需要考虑QoS支持的业务时,应用设计者能够参照制定详细的QoS需求,系统工程师可以参考评估各个QoS需求之间的权衡关系,从而进行网络的整体设计。
Research on QoS in WSNs has been isolated in the past, either specifically at certain functional levels or specifically tailored to certain application scenarios. According to the reference architecture of WSNs, the dissertation discusses the definition of QoS requirements and the impact of low-level QoS requirements on the high-level QoS requirements in order to arrive at an overall QoS framework, and then analyze them according to the relationship between the various QoS requirements There are tradeoffs and how to find such tradeoffs so that you can gain insight into the interplay of QoS requirements in WSNs. When there is a service in the wireless sensor network that needs QoS support, the application designer can refer to formulate detailed QoS requirements. The system engineer can make reference to the trade-off relationship between each QoS requirement so as to design the whole network.
