%X 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.
