| 摘 要： | 在移动多sink无线传感器网络应用中，传感器节点感知目标信息并暂存起来，sink通过向网络发出查询来收集感知信息，如何保障数据发布过程中的服务质量(QoS)是具有挑战性的工作。首先分析数据发布过程的特点，提出将能量消耗、查询成功率和服务时延作为数据发布协议服务质量的核心指标。然后讨论了数据发布协议相关技术与QoS核心指标间的关联关系，给出数据发布协议的QoS协商过程。最后分析了未来的研究趋势，为QoS感知的数据发布协议设计提供参考。

| Abstract: | In wireless sensor networks with mobile multi sinks,mobile sinks roam in the network area and gather data about target via sending out rectuest to network. How to guarantee the quality of service(QoS) in processing of data dissemination is a challenging work. Firstly, based on analyzing the features of data dissemination protocols, indicators system of QoS was presented. It regards energy consumption, query success rate and service delay as core indicators. Then the relation between technologies of data dissemination protocols and core indicators of QoS was discussed. And then a consultation mechanism of QoS was proposed which can provide reference for future work. Finally, the research trends were pointed out. |
