Peer-to-Peer Instant Messaging and Presence Services over Wireless Ad Hoc Networks

Session Initiation Protocol (SIP) has been extended by IETF SIMPLE Working Group to enhance the basic protocol with Instant Messaging and Presence functionalities. These extensions are, however, dependent on the Internet and SIP infrastructure. Ad hoc networks being devoid of any such infrastructure, require auxiliary mechanisms to support such extensions. In this paper, we present a brief overview of the SIP extensions followed by a proposal to integrate a cluster based ad hoc routing protocol with the instant messaging and presence services.
