On the performance response of delay-bounded energy-aware bandwidth allocation scheme in wireless networks

Abstract

This paper proposes a joint power and resource allocation methodology, by using a node-centric scheme. Each node estimates the throughput Θ(t _s ) and tunes the proposed path-aware energy conservation mechanism, according to requested delay constrained resources, as well as the bandwidth resources that the associated channels can handle in time. The combined power and frequency bandwidth allocation scheme is estimated for delay bounded streams, in order to provide the least power cost path to be traversed by the stream. The time-constrained transmissions are being manipulated in a collaborative manner through either the Radio Access Technologies or through the Peer-to-Peer mobile collaboration. The conducted simulation experiments and the results extracted, show that the proposed scheme could be applied to different Radio Access Technologies with variable delay-bound constraints, providing nodal and path-aware energy manipulation, whereas the proposed scheme minimizes the estimated power consumption of each device and prolongs the node's lifetime.
