Throughput for Packet Radio Networks with Dynamic Power Levels

Abstract

A packet radio network consists of a set of computers whose intercommunication needs are served by mobile radios. In this work, relatively simple models are used to determine attainable throughputs in such networks under a variety of routing scheduling strategies. In particular, we assume uniform traffic requirements between all pairs of nodes and an idealized capture effect. Through the derivation and numerical solution of a differential equation, it is shown that a large network of nodes which are uniformly spaced along a line and which uses slotted-Aloha channel access can attain a throughput of 2.05/e if its transmitters can dynamically adjust their power, as opposed to a 1/e throughput attainable in fixed-power networks.
