An Adaptable Service Overlay for Wide Area Network Service Discovery

Chameleon is a service-oriented peer-to-peer (P2P) overlay which employs a unique 2-tier maintenance system, adaptable to variations in the available bandwidth of the hosting device. For devices with low available bandwidth, Chameleon uses an opportunistic maintenance technique, and for high bandwidth devices, an active maintenance technique. This allows Chameleon to adapt to environmental changes of mobile device, such as switching between 802.11 and GPRS depending on network availability. Chameleon´s suitability for use in mobile networks is further augmented by its support for Meta Service Discovery, our technique for discovering multiple service discovery mechanisms in P2P networks, hi this paper we show how Chameleon can be used with this service discovery technique in a wide area network.
