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)
—In this paper, we propose traffic-sensitive dynamic sectorization of base stations (BSs) for energy savings in OFDMA-based cellular access networks. Under the proposal, following the temporal variation of traffic level, BSs are dynamically recon-figured using fewer sectors. User data rate, service continuity and network coverage are also maintained. A(More)
Energy efficiency is one of the top priorities for future cellular networks, which could be accomplished by implementing cooperative mechanisms. In this paper, we propose three eNB-centric energy saving cooperation techniques for LTE systems. These techniques named as intra-network, inter-network and joint cooperation, involve traffic-aware intelligent(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 two-dimensional dynamic network provisioning mechanism for enhancing the energy efficiency in OFDMA-based cellular systems. Proposed scheme, named as joint dynamic sectorization and(More)
The densities and viscosities of dodecyltri-methylammonium bromide (DTAB), glycine, and rac-alanine in water and DTAB in glycine/alanine aqueous solutions have been determined at 288.15, 296.15, 304.15, 312.15, and 320.15 K. The apparent molar volumes (u v) were obtained from these density data. The limiting apparent molar volumes (u v 0) and experimental(More)
