Automotive telematics has become an important capability of high-speed rail systems, which are increasingly popular in the era of green technology. As train speeds increase, communications between devices on the train and devices outside the train encounter difficulties, and maintaining high quality communication is a major challenge. Moreover, handovers on high-speed trains occur more frequently, and have shorter permissible handling times. In this paper, the proposed 2MR scheme takes the advantage of the physical size of high-speed trains to deploy two Mobile Routers (MRs) in the first and final carriages.
