چکیده

Support for real-time multimedia session services, such as real-time interactive voice-and-video-over-IP applications, is highly desirable in a mobile Ad Hoc Network (MANET). This paper presents a service discovery mechanism as an extension of the proactive OLSR (Optimized Link State Routing) protocol, enabling real-time interactive multimedia session applications using the Internet Engineering Task Force’s (IETF) standard Session Initiation Protocol (SIP) in MANET. Effectively applying the crosslayer design between the networking and the application layer, a unified SIP service location distribution mechanism is proposed which can discover SIP service capabilities and server locations. Performance analysis and simulation results of the proposed scheme as applied to SIP MANETs running on OLSR are presented.
