Optimization of quality of service (QoS) parameters using Contract Net Protocol in Ubiquitous Computing

To generate large-scale resource management, grid based computing play a crucial role. It represents various geographically dispersed computational resources, i.e. workstations, PCs, cluster, storage devices, and database as fused integrated system, which can play dual roles of synchronized resource donator and consumer in such distributed computation environment. Now a day, in ubiquitous environment the use of embedded devices and mobile has grown intensively, produces abundant data which need to be processed. But, as these ubiquitous devices have limited power in terms of bandwidth, CPU, battery, storage; these applications services require more powerful computational resources. To fulfill these requirements, Grid can act as promising computational services provider to ubiquitous computing application. In this paper, we represent a competitive model, describing the interaction between Grid computational resources as competing service provider whereas ubiquitous applications as consumer. We represent Contract Net Protocol model for such competitive environment for quality of service (QoS) offered by Grid Service Provider (GSP). We have also studied model for the same competitive environment based on equilibrium behavior under definite QoS provision and the stochastic demand. Our proposed model and performance results give out appropriate strategies for real-time grid environment.
