| 摘 要： | 本文中提出了一种基于数据的信息质量而提供QoS支持的跨层协议,文中先阐述了无线传感器网络与传统网络在QoS支持上的不同的需求和特点,并提出了跨层优化的概念,指出无线传感器网络采用跨层优化的可行性和必要性.本文通过划分优先级来对网络提供不同的服务质量.数据包的优先级主要反应了数据包中所含的信息质量,由网络的应用层决定,而后再根据数据优先级的不同在MAC层提供不同的服务,从而实现跨层的QoS支持.

| Abstract: | A cross-layer protocol providing the QoS support based on the information quality is proposed.The difference of requirements and specialties on QoS support between the Wireless Sensor Networks(WSN) and tranditional networks is explained at first.Then,the concept and the feasibility and the necessary of cross-layer optimization is discribed.In this paper,the different QoS is provided by dividing priority.The priority of the data packet reflects the information quality included in the packet,which is decided in the application layer of the network.And the different QoS is provided in the MAC layer according the priority.So the cross-layer QoS support is realized. |
