TRANSMISSION RANGE CONTROL IN MULTIHOP PACKET RADIO NETWORKS.

A model is presented for analyzing the performance of transmission strategies in a multihop packet radio network where each station has adjustable transmission radius. A larger transmission radius will increase the probability of finding a receiver in the desired direction and contribute more toward progress if the transmission is successful, but it also has a higher probability of collision with other transmissions. The converse is true for shorter transmission range. The model is illustrated by comparing three transmission strategies. The results show that the network can achieve better performance by suitably controlling the transmission range. One of the transmission strategies, namely transmitting to the nearest forward neighbor by using adjustable transmission power, has desirable features in a high-terminal-density environment.link_to_subscribed_fulltex
