Efficient energy management in buildings is becoming an important requirement aimed at reducing energy costs and environmental pollution. Setting a monthly budget for energy consumption, and consequently energy cost, of buildings is being practiced by several organizations in a bid to reduce their carbon footprint. However, the impact of such an energy budget on the indoor comfort of users in a building...
Power saving-semipersistent scheduler (PS-SPS) for voice over LTE (VoLTE) traffic was proposed in the downlink of LTE-A cell to reduce the energy consumption of the eNodeB. PS-SPS introduces the energy saving ability through a modification of traditional SPS (T-SPS) in allocating downlink Physical Resource Block (PRBs) to VoLTE users. In this paper, we first identify the drawbacks of PS-SPS that might...
Long Term Evolution-Advanced (LTE-A) that promises better support to richer applications is expected to catalyze the explosive growth in the number of subscribers and their demand for traffic. Such unprecedented growth will push the limits of energy consumption in the operators network. Hence, there is a need to introduce power saving mechanisms in LTE-A to minimize the energy consumption. In this...
Power saving in Mobile Wireless Broadband networks is one of the vibrant, important and current areas of research. Mobile WiMAX based on IEEE 802.16e standard provides different Power Saving Modes (PSM) like sleep mode and idle mode to save power in Subscriber Station/Mobile Station(s). The forthcoming IEEE 802.16m standard has extended idle mode with introduction of concept of primary and secondary...
