传感器使能网格可以将关于物理环境的真实的数据与从网格架构导出的大量计算资源相结合。设计一个传感器网格的主要挑战之一是如何有效地调度传感器资源的用户作业的传感器资源的集合。本文提出了一种基于Agent的传感器网格资源分配方案，根据Agent之间的协商结果将传感器资源分配给合适的传感器网格用户。该模型由两种类型的代理组成：传感器资源代理代表传感器网格底层传感器资源提供者的经济利益，传感器用户代理代表网格用户应用程序使用网格实现目标的利益。这两种代理类型之间的相互作用是通过市场机制来调节的。我们模型的传感器分配问题，通过引入传感器效用函数。目标是找到使总利润最大化的传感器资源分配。提出了一种分布式传感器资源优化分配算法。最后对算法的性能进行了评估，并与其他传感器网格资源分配算法进行了比较。文中还给出了该方法的应用实例。
Sensor enabled grid may combine real time data about physical environment with vast computational resources derived from the grid architecture. One of the major challenges of designing a sensor enabled grid is how to efficiently schedule sensor resource to user jobs across the collection of sensor resources. The paper presents an agent based scheme for assigning sensor resources to appropriate sensor grid users on the basis of negotiation results among agents. The proposed model consists of two types of agents: the sensor resource agents that represent the economic interests of the underlying sensor resource providers of the sensor grid and the sensor user agents that represent the interests of grid user application using the grid to achieve goals. Interactions between the two agent types are mediated by means of market mechanisms. We model sensor allocation problems by introducing the sensor utility function. The goal is to find a sensor resource allocation that maximizes the total profit. This paper proposes a distributed optimal sensor resource allocation algorithm. The performance evaluation of proposed algorithm is evaluated and compared with other resource allocation algorithms for sensor grid. The paper also gives the application example of proposed approach.
