The peer-to-peer (P2P) networks undoubtedly receive wide attention because of their broad applications such as file sharing and media streaming services. Substantial research efforts have contributed to their success of P2P paradigms in the traditional, wired network environments. Whereas the advance of modern wireless and mobile network systems, e.g., WLAN, WiMAX, 3G, 3.5G, and emerging 4G, can offer faster broadband access, wired Internet may not be the sole vector for P2P services. Mobile users now have increasing interests to have P2P services anywhere, anytime through their mobile handheld devices.

Mobile environments have special characteristics, such as highly variable connectivity, mobility, disconnection, location-dependency, energy and resource sensitivity, communication asymmetry, high bandwidth expense, and the diversity in wireless networks, rendering new challenges, problems and issues for research in mobile P2P computing. However, prior results obtained for the "static" P2P networks cannot be directly deployed in such environments. New derivatives or modification to present P2P data dissemination and management strategies are required. As a result, research works should propose promising solutions that enable efficient an reliable mobile P2P information services in the province of mobile P2P computing.
