Support of Multimedia SIP Applications over a Proactive MANET Using Cross-Layering Design; Briefing charts

摘要

DESCRIPTION: A general problem when deploying services in a MANET, is that the service location issue requires specific considerations due to dynamic network topology changes. SOLUTION: We apply a cross-layer design approach to advertise SIP proxy and SIP User Agent server location information in a unified mechanism embedded in a proactive link-state routing protocol. Our proposal can differentiate the SIP proxy server and SIP User Agent server (UAS) in the location information advertisement and can thus support both proxy-based and proxy-less SIP MANET network architectures in one unified server location distribution mechanism.
