The objective of pervasive computing is to allow users to perform their tasks in a transparent way regardless of device features. Resources on devices should be exploited to provide services in order to perform user tasks. When there is no exact match for the user task in the environment, the capabilities of available devices should be combined to perform the user task. Seamless Service Composition (SeSCo) abstracts device capabilities as services and leverages existing work on graph algorithms to perform service composition. A lightweight framework, PerSON (Service Overlay Network for Pervasive Environments) was developed to provide a service overlay network for the Pervasive Information Community Organization (PICO) middleware.CHAPTER 5 PROTOTYPE IMPLEMENTATION PerSON (Service Overlay Network for Pervasive Environments) creates a service overlay network on top of different physical and logical networks, facilitating connections between clients andanbsp;...
