In a wireless mobile network with wireless multihop transmissions such as a mobile adhoc network and a wireless multihop access network, end-to-end bandwidth from a source mobile computer to a destination one is less than 1/3 of bandwidth of a wireless communication link due to random waiting time for contention avoidance and RTS/CTS control for solving a hidden terminal problem. In this paper, the authors propose an adhoc routing protocol and a message transmission protocol with transmission power control for achieving higher end-to-end bandwidth. The maximum end-to-end bandwidth in the proposed protocols is 1/2 of bandwidth of a wireless communication link. Simulation results show that the proposed protocol provides about 60% higher end-to-end bandwidth than a conventional no power control protocol. In addition, it provides almost the same connectivity with conventional no power control protocols if density of mobile computers is sufficiently high.
