Summary:
In this paper, we propose a medium access control(MAC) protocol for supporting telematics service in the road environment, which requires the guarantee of a delay bound on end-to-end transmission and high transmission reliability in a multi-hop network. In order to guarantee a delay bound on end-to-end transmission and high transmission reliability in a multi-hop network, the proposed MAC adopts the access mechanism based on time division multiple access(TDMA) and uses the superframe structure which considers an end-to-end transmission. Moreover, the proposed MAC can extend a network coverage by using special device, T-sink. Through experiments in the real testbed where the proposed MAC is implemented, we can show that the proposed MAC is appropriate for the telematics service in the road environment.
