On Supporting Mobile Peer to Mobile Peer Communications

In this paper, the authors propose a new method for assessing the sociability scalar of a mobile peer by the network, most importantly with no involvement of the mobile peer. The sociability metric can help in the Application Layer Traffic Optimization (ALTO) guidance in Mobile Peer-to-Mobile Peer (MP2MP) scenario to scale up the database search of an ALTO server. The proposed method models encounters of mobile peers with predetermined areas, such as cells, tracking areas, gateway service areas, etc, depending on the targeted granularity.
