Or maybe I made a mistake?

The effect of "churn" is not negligible. An comprehensive analysis of the impact of churn is available in: A. Binzenhoefer and K. Leibnitz: "Estimating Churn in Structured P2P Networks.", 20th International Teletraffic Congress (ITC20), Ottawa, Canada, June 2007. available at http://www3.informatik.uni-wuerzburg.de/papers/conf_261.pdf There is already a lot of research going. Much of this will available soon in a special book on Mobile P2P systems: Boon-Chong Seet (Edt.): "Mobile Peer-to-Peer Computing for Next Generation Distributed Environments: Advancing Conceptual and Algorithmic Applications", IGI Global, Hershey (USA), April 2009.

In mobile environments,peer connections become location-dependent and may be vulnerable, disconnetions and reconnections can ouccur more frequently, you should address these issues when a peer is registering or searching the overlay.Also, there is mobility issue in federated overlay architectures. As for the technical meaning of mobile p2p, we think it could include the p2p overlay for mobile ad hoc networks(MANET) and sensor networks, p2p architectures for integrated MANETs and wide-area networks,Mobile P2P on different bearer serveces: 2.5/3G(GPRS/UTMS), 802.11(WLAN), mobile P2P SIP, and so on. Looking for your responses. Best regards, Bin Long On Mon, Feb 9, 2009 at 4:12 PM, Song Haibin <[email protected]> wrote: Hi David, I think you get to the point. The p2p layer connection continuity is important for the mobile overlay network. I want to know if some generic mobility techniques which are independent of the applications could be used to solve this problem?

Frecuent changes has to be managed in order to route messages efficiently. It is not the same as churn, but it introduces similar challenges, IMHO.

Mobility is inherent on the Internet and can be implemented in several ways. Or are you referring to to mobile phones not connected to the Internet? Where is the protocol capability difference between a laptop, a netbook and a smart phone? This sounds simplistic, but wireless to me is a wire into the Internet, unless we talk about some closed network, and please tell me why would I buy it?

The underlying fact is that with the issue of 3G lisences in China and emergence of more and more cell phone applications, our team think we should do some work to extend the P2P technic from PC to mobile devices.

I have seen mobile P2P researches and discussions existing for a while. Should we have a separate WG because of its technical significance and complexity, I am not sure. Important is that we need to work on it. Are you interested in mobility management only, e.g. handover, or more?
