摘要

Due to development of computer and network technologies, mobile computer networks have become widely available. Since mobile computers such as handheld PCs and PDAs and mobile sensor nodes which are required to be small and light weight have only limited battery capacity, a radius of a wireless signal transmission range is also limited. In order to achieve higher connectivity even though a network is composed of mobile computers communicating with limited wireless signal transmission power, a wireless multihop transmission is applied where messages from a source mobile computer to a destination one are forwarded by a sequence of intermediate mobile computers. Until now, many ad-hoc routing protocols have been proposed. In a MAC protocol based on CSMA/CA such as IEEE802.11 for a wireless LAN, for avoidance of collisions of signal transmitted from multiple mobile computers, RTS/CTS control is introduced. Hence, only one neighbor mobile computer transmits wireless signal at a time and a mobile computer gets less chances to transmit messages. This leads to reduction of end-to-end bandwidth along a multihop message transmission route. In order to solve this problem, we propose a method to extend end-to-end bandwidth with wireless signal transmission power control and design protocols for route detection and for message transmission along the detected route.
