Peer-to-peer mobile network architecture

Philippe Charas

An individuals ultimate independence from unwanted ownership and control can be obtained in a Mobile Peer to Peer (MP2P) environment. This paper takes a historical view on the subject of mobile networks and underscores some of the main architectural principles enabling MP2P. The concept of local policy enforcement is introduced as a mental tool to define terminal centric control, as opposed to network centric control. This concept is further expanded to incorporate a mobile architecture including a ubiquitous end user device, where business model related policies are stored. In this way, the architecture becomes business model independent, and business model related policies stored separately in a terminal based policy repository reflect any relationship that the individual has engaged into. This includes Personal Area Networks and AD-HOC networks as well. Another such relationship can be a P2P relationship, which can be combined with another relationship concerned with mobility.
