In inter-vehicle networks, it is required that collision warning messages be forwarded over multiple hops with significantly short delay. Cut-through packet forwarding is known to effectively reduce forwarding latency. However, it suffers from reliability issue, which can be severe in wireless networks, due to fading, users' mobility, and so on. This paper(More)
— In this paper we study the channel efficiency of Mobile Ad hoc Networks (MANET) and try to trade off between the progress and the instantaneous rate when forwarding packets in the fading environment. We define a new metric—bit transfer speed (BTS)—as the ratio of the progress made towards the destination to the equivalent time taken to transfer a payload(More)
—Although the near-far effect has been considered to be the major issue preventing CDMA from being used in ad-hoc networks, in this paper, we show that the near-far effect is not a severe issue in inter-vehicle networks for safety driving support, where packet transmissions are performed in the broadcast manner. Indeed, the near-far effect provides(More)
