Content sharing using P2PSIP protocol in Wi-Fi direct networks

Efficient sharing of content among users in a close area is a challenging problem remaining in smart devices. This paper presents an architecture which allows users in a group to experience the ubiquitous and real -time sharing service of resource like image, video and website address. Our approach is motivated by taking advantage of the novel industrial standard Wi-Fi Direct which allows Wi-Fi terminals to establish a Wi-Fi network without a real Access Point (AP) and P2PSIP protocol which enables real-time communication using Session Initiation Protocol (SIP) in a Peer-to-Peer (P2P) fashion. Accordingly, with instant ad-hoc peer-to-peer connectivity, content sharing among users is conducted more easily and quickly. We describe a prototype application and discuss major practical requirements of the proposed system.
