We can choose the data transmission rate to be alternative or fixed among the duration through 54Mbps to 1Mbps for the purpose of experiment. Routing protocol supporting multihop communication is embedded with the consideration of microwave propagation condition to improve total throughput, total error rate and so on rather than the original protocol. In this paper, we will show the structure and wireless communication characteristics and the performance of moving pictures streaming at multihop communication with camera and codec connected WACNet test system on the mobile experimental cars.
