Service-oriented networking platform on smart devices This study presents the design of a service-oriented networking platform to offer dynamic networking services in support of mobile group communications among connected smart devices. This platform enables users to access smart services anywhere and anytime with embedded devices while satisfying their requirements of various smart services. The proposed platform adopts a session initiation protocol (SIP) protocol as service signalling protocol that provides high extensibility and compatibility with an existing service system. The overlay network structure suggested in our platform provides an advantage of building a scalable and dynamic service network based on multiple smart zones. Furthermore, the quality of end-to-end service in dynamic network environments is guaranteed by virtue of the smart delivery scheme in the platform.
