Buffer dynamic management for energy-aware network

Abstract

Energy is a major issue in networks especially in local network implementation. Some technological solutions have been developed to treat this problem e.g. Re-engineering, Dynamic Adaptation, Smart Sleeping. We present an original and alternative adaptive solution from a proposed extended Adaptive Link Rate (ALR) module, which relates energy and router queue-length. Applying a controller already proposed by authors, the router queue-length is adapted in order to follow a reference given by the extended ALR module, that guarantees an energy reduction. The approach is validated in the network simulator “NS-2”. Within ADREAM building at LAAS-CNRS, this “control green” will allow to improve energy consumption regarding traffic load and available energy in communication networks.
