Power Control Routing for High Throughput in Mobile Ad Hoc Networks

چکیده
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.

Improving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR
Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...
