Power Control Routing for High Throughput in Mobile Ad Hoc Networks.
Masakazu Ono, Hiroaki Higaki · 2004
A Mobile computer changes its location from time to time. Wireless communication protocols, e.g. IEEE802.11 and HIPERLAN, are widely available in mobile ad-hoc networks. By controlling signal transmission power in a mobile computer, transmission range of the signal is changed. By increasing the signal transmission power, the number of hops for transmitting a message between two mobile computers is reduced. On the other hand, by reducing the signal transmission power, the probability of contention and collesion in signal transmission is also reduced. Hence, there is a trade off in controlling the signal transmission power in order to reduce an end-to-end message transmission delay. This paper proposes two algorithms for finding another path by controlling signal transmission power for achieving shorter message transmission delay. These algorithms are invoked locally in each mobile computer on a path, i.e. these are not centralized one in a mobile ad-hoc network. 1.
