This paper presents an implementation of a multimedia conferencing system on a mobile ad-hoc network over vehicles using SIP (Session Initiation Protocol) and Multicast. SIP and Multicast are applied to our multimedia conferencing system to manage inter-vehicle communication efficiently. In order to demonstrate the performance of our system, we have measured transmission characteristics such as throughput, delay and data loss rate on a test bed. A test-bed has been implemented to support multimedia conferencing system and to evaluate the feasibility of high-speed networking between vehicles for emergency notification. Through the experiment, we have used UDP and OLSR (Optimized Link State Routing) to measure transmission metrics. Our multimedia conferencing system operates well on a high speed mobile ad-hoc network for inter-vehicle communication.
