    Abstract

    This master thesis proposes an implementation of a SIP client offering presence and instant messaging functions, under the assumption that SIP proxies are not presence-enabled. This implementation relies on SIMPLE, a SIP-based protocol, whose purpose is to resolve interoperability issues among various SIP clients. Our client has also been enhanced with mobility support without continuous connectivity at application-layer level. Throughout this paper, we provide an introduction to SIP, presence, instant messaging and mobility support.
