Abstract
Nodes in Ad Hoc network are typically powered by batteries, so how to improve energy efficiency, save energy and prolong the life span of networks are critical problems at all layers of the protocol stack. IEEE802 11 specifies power saving mechanism (PSM) under distributed coordination function (DCF) for energy efficiency. On the basis of an analysis and comparison IEEE802 11PSM, this work proposes an adaptive power saving mechanism (EPSM) EPSM improves PSM model that could only send one package in one BI, dramatically reduces transfer delay, and prolongs the life span of central nodes to save energy using central nodes alternant wake- up The results of simulation show that EPSM has better performance than PSM in decreasing transportation delays, saving energy, and prolonging life span of nodes.
