摘要: 资源调度是无线传感网络中移动节点的核心和富有挑战性的问题。如何提高移动节点资源使用率并取得最大利润是服务商的最终目标。通过非强占优先权排队G/G/1模型,满足不同等级数据QoS,利用线性分段函数使系统成本最小。进而基于成本函数和收益函数模型,求出不同级别信号动态分配比例,从而得出用户与服务商都满意的结果。结果表明,动态资源调度系统,不仅能够保证不同级别数据的QoS要求,也可使服务提供商的利润最大化。

Abstract: ob scheduling system is the core of data mule and challenging problem in wireless sensor network. How to improve the efficiency of resource and the maximum profit are the ultimate goal of service providers. In at first, by establishing the preemptive priority queuing modle of G/G/l,to meet the QoS of the transmit data at different levels,the linear piecewise functions are used to make the system cost minimum. Furthermore, based on the cost function and profit function of queuing system, to get dynamic allocation rate, and to get the corresponding value which service users and service providers are satisfied with. The results show that, the dynamic resource scheduling system, not only can ensure the different data's QoS requirements, but also can provide the maximize profits for the wireless sensor network service providers.

Key words: Job scheduling system, Data mule, Preemptive priority, Profit
