Abstract
A protocol for extending session endpoints in an ad-hoc network environment first performs device discovery to determine local devices within its coverage area and the capability of those devices. These local devices then exchange session descriptions with the endpoint device. If the current session may be supported by one of the local devices, the endpoint device, responsive to a command from an user, transfers the session endpoint to the local device and the endpoint device acts as a proxy for the local device in the session. Optionally, if the local device has a path to the correspondent node that is independent of the path through the endpoint device, it establishes the session along this path and then signal the endpoint node to terminate its session.
