A LOCALIZED BROADCAST SCHEME FOR MINIMIZING POWER CONSUMPTION IN WIRELESS MOBILE AD HOC NETWORKS

摘要

In ad hoc networks, broadcasting is a primitive operation to support many applications and it is also an expensive process in terms of power consumed. Preserving energy and ensuring a high delivery ratio of broadcast packets are crucial tasks for broadcasting in ad hoc networks. This paper proposes a localized broadcast scheme for use in ad hoc networks using variable-range transmission power. Varying transmission range dynamically by individual broadcast relaying node contributes to the overall power savings and interference alleviation during communication. We analyzed the performance of the proposed scheme and compared it to one of the existing schemes that employ variable transmission power and other prevalent broadcast schemes based on common-range transmission power.
