This paper1deals with the seamless multimedia service mechanism in vehicle communication network(VCN). The proposed mechanism uses caching/switching/multicasting agent(CSMA), a partial of GPS information and multicast transmission in VCN network. The CSMA controls some smart access points(SAP) with buffer, and may generate multicast group address for live-video in local-vehicle-network(LVN). And it manages serviced video items, switches multimedia packets to SAPs requesting service, and performs smooth handover for vehicles using table. The SAP generates modified virtual address(IP address) for vehicles that enter the VCN network. The proposed virtual IP address consists of LVN network ID, vehicle ID, GPS information(driving distance) and a driving direction mode bit. And the CSMA and SAP provide smooth handover using their service tables and a seamless multimedia service. Also, this proposed mechanism may provide promptly multicast service for live-video because multicast mechanism is performed within the VCN network, and reduce the possibility of cutoff service and packet loss because it uses GPS in-formation.
