XTC+: a description and analysis of a topology control mechanism for MANETs

Abstract

The Objective of topology control mechanisms (TCM) is to modify the natural network topology toward a determined objective. In MANETs the objective is to minimize power consumption and/or interference. In general topology control is achieved through deliberate changes in transmission power (and possibly other parameters such as antenna direction and channel selection) that directly affect the local connectivity of a node, and consequently affect the whole topology of the network. By focusing on the stage in which information is collected in an existing topology control algorithm called XTC, this paper shows the possibility of extending the network performance optimization present in this algorithm. It is then an addition to an already existing optimization concept.
