P2P Group Network architecture for ubiquitous service in heterogeneous mobile devices

IPTV is considered a stepping stone into a ubiquitous area as the home networks´ main business model. We propose the P2P chord service overlay network model to provide services and make sharing resources among mobile devices easy. The proposed SGN (Spot-based Group Network) uses hierarchical service delivery network architecture. It delivers services and resources among distributed mobile devices. We suggest three business models which are plausible ubiquitous service architectures.
