Improving energy efficiency, reducing carbon footprint and self-sustainability are key concerns in the design and development of future green communication networks. Therefore, in this paper, a novel energy efficient cellular access network architecture based on the principle of ecological proto-cooperation is proposed. Furthermore, for the first time, the(More)
The rapidly increasing contribution towards global warming from the information communication technology (ICT) sector is a clear indication of the need for energy efficient green communication networks. For instance, in the case of cellular networks, over 80% of the total energy is consumed at the access network. On the other hand, incorporating(More)
We propose a distributed inter-base station (BS) cooperation assisted load balancing framework for improving energy efficiency of OFDMA-based cellular access networks. Proposed cooperation is formulated following the principle of ecological self-organization. Based on the network traffic, BSs mutually cooperate for distributing traffic among themselves and(More)
Energy efficiency is one of the central concerns for future cellular networks, which could be accomplished by adaptively reconfiguring the networks with the changing traffic environment. In this paper, we propose and analyze a dynamic sectorization scheme of evolved node Bs (eNBs) in long term evolution (LTE) systems for saving energy at radio access(More)
In this paper, by exploiting the availability of multiple cellular radio access networks (RANs), we propose a novel two-level cooperative access network framework for superior energy efficiency. Geographically co-located RANs mutually cooperate each other through the combined use of base transceiver station (BTS) level intranetwork cooperation and RAN level(More)
Smart Grid (SG) is envisioned as the future of the electricity delivery system, which can be intelligently monitored, and operated via communication links. The Smart Meter (SM), one of the key elements of the SG, identifies power consumption and communicates with the control center. The long term evolution (LTE) network has become an attractive candidate(More)
In this paper, we propose traffic-sensitive dynamic sectorization of base stations (BSs) for energy savings in OFDMAbased cellular access networks. Under the proposal, following the temporal variation of traffic level, BSs are dynamically reconfigured using fewer sectors. User data rate, service continuity and network coverage are also maintained. A(More)
Conventional peak-traffic based provisioning of cellular mobile networks leads to a significant wastage of electrical energy. Therefore, we propose a novel traffic-aware twodimensional dynamic network provisioning mechanism for enhancing the energy efficiency in OFDMA-based cellular systems. Proposed scheme, named as joint dynamic sectorization and(More)
