提出了一种基于中间件、面向服务的无线传感器网络主动QoS体系QISM,对其设计思想、体系结构、关键模块和工作过程进行了论述.基于应用和网络反馈协商的动态调节机制,基于中间件和服务发布与订阅的体系结构,以及基于Topic和功能域的表达方式,是QISM的重要特点.QISM通过对应用和网络的动态调节,使网络最大限度的支持应用,应用最大程度的适应网络,从而更好地保证了应用的完成,延长了网络生命期.针对典型场景的仿真结果表明,QISM机制具有良好的QoS控制能力和灵活性,支持复杂应用,且同网络结构形式无关. Aiming at the problem of dynamic adjustment mechanism based on application and network feedback negotiation, based on middleware and service-oriented active QoS architecture QISM, the design idea, architecture, key modules and working process are presented. Based on middleware And service publishing and subscription architecture, as well as the expression based on Topic and function domain, is an important feature of QISM.QISM through the dynamic adjustment of applications and networks, the network to maximize the support applications, the application of the greatest degree of adaptation to the network, So as to ensure the completion of the application and prolong the lifetime of the network.The simulation results of typical scenarios show that the QISM mechanism has good QoS control capability and flexibility and supports complex applications and has nothing to do with the network structure.
