Abstract

The Service Oriented Architecture (SOA) is used extensively in ubiquitous computing environments. Using external service orchestration, services can be composed into applications. Since cooperation takes place between services that are scattered over the Internet and belong to different parties, there is a growing need to protect the ownership of service providers and keep the security of communication messages in service composition. This paper shows the details of a service-oriented virtual community overlay network designed for secure external service orchestration. It can also provide contracted QoS guarantees that will definitely affect the overall performance of ubiquitous applications. Further, it highlights the working principle of access control policies as well as a service behavior monitoring mechanism using an example scenario.
