Energy saving in the Internet has become important since the massive new applications are increasing tremendously, along with their energy consumption. In this paper we propose an energy efficient algorithm based on multi-topology routing. Since traffic flow dynamically changed in actual IP network scenarios, the proposed algorithm has to adapt the network energy consumption to daily traffic scenarios...
Based on the protocol of IEEE 802.11 for ad hoc networks, the distributed coordination function (DCF) of ad hoc networks was modified, and an adaptive minimum contention window binary exponential backoff algorithm (AWBEB algorithm) was presented. We use a 2D Markov chain model to educe the stationary distribution probabilities and the probability that a given node will transmit in an arbitrary time...
