“…In [74] statistical report is described after examining the NTT DoCoM (It is the mobile company in Japan) that 3G feature is the most power consuming part of a mobile system because it works on the radio signals [75][76] and compares a number of routing protocols on the basis of energy consumption: one is Ad Hoc on-demand distance vector routing (AODV) [77][78][79] which can be used for different detection techniques in wireless Ad Hoc networks [96]. This protocol works on when a node is used to transfer data.…”

Abstract-As the mobile devices are widely used in this world. With the increasing number of users, the numbers of customized applications are also introduced for these users according to their own requirements but on the other hand, there is a dire need of a system which must be energy conserved, estimated and maintained. A survey of energy consumption in mobile phones is presented in this paper with the factors at which the consumption of the energy depends on i.e. Energy consumed by OS, by hardware, by applications, by the user to interact with the applications, by wireless, by the sensor network. The energy management models and frameworks are also discussed in this paper.

“…Thus, we consider the network equipment including the optical network terminals and radio base stations, but excluding personal computers (PCs), laptops and mobile devices such as cellular phones, smartphones and tablet PCs. Additionally, the mobile devices are optimized for low energy consumption and usually consume just a small fraction of the energy consumed by base stations and fixed-access equipment [23]. Since we consider the use of different power saving methods in the model for energy consumption, we differentiate between several levels of power consumption that correspond to several operation modes of the equipment.…”

Optical/wireless convergence has become of particular interest recently because a combined radio wireless and optical wired network has the potential to provide both mobility and high bandwidth in an efficient way. Recent developments of new radio access technologies such as the Long Term Evolution (LTE) and introduction of femtocell base stations open new perspectives in providing broadband services and applications to everyone and everywhere, but the instantaneous quality of radio channel varies in time, space and frequency and radio communication is inherently energy inefficient and susceptible to reflections and interference. On the other hand, optical fiber-based networks do not provide mobility, but they are robust, energy efficient, and able to provide both an almost unlimited bandwidth and high availability.In this paper, we analyze the energy efficiency of combined wireless/optical access networks, in which LTE technology provides ubiquitous broadband Internet access, while optical fiber-based technologies serve as wireless backhaul and offer high-bandwidth wired Internet access to business and residential customers. In this contest, we pay a particular attention to femtocell deployment for increasing both access data rates and area coverage. The paper presents a novel model for evaluating the energy efficiency of combined optical/wireless networks that takes into account the main architectural and implementational aspects of both RF wireless and optical parts of the access network. Several hypothetical network deployment scenarios are defined and used to study effects of femtocell deployment and power saving techniques on network's energy efficiency in urban, suburban and rural areas and for different traffic conditions.

“…Furthermore, the power consumption of ICT is approximately 4 % of the annual energy consumption and it is expected that this number will double within the next 10 to 15 years [3]. Within ICT it is shown that the radio access networks are a large contributor to CO 2 emissions [3], [4], [5]. The base stations are responsible for roughly two-thirds of the CO 2 emissions of these radio access networks [4].…”

“…The base stations are responsible for roughly two-thirds of the CO 2 emissions of these radio access networks [4]. NTT DoCoMo recently investigated the daily power consumption per customer [5]. They found a power consumption per customer of 0.83 Wh for a terminal and 120 Wh for the mobile network resulting in a consumption ratio of about 1:150 for terminal versus network.…”

Abstract-The power consumption of wireless access networks will become an important issue in the coming years. In this paper, the power consumption of base stations for mobile WiMAX, HSPA, and LTE is modelled. This power consumption is related to the coverage of the base station. The considered technologies are compared according to their energy efficiency for different bit rates at a bandwidth of 5 MHz. For this particular case and based on the assumptions of parameters of the specifications, HSPA is the least energy-efficient technology. Until a bit rate of 11 Mbps LTE is the most energy-efficient while for higher bit rates mobile WiMAX performs the best. Furthermore the influence of MIMO is investigated. A decrease of about 80 % for mobile WiMAX and about 74 % for HSPA and LTE for the power consumption per covered area is found for a 4x4 MIMO system compared to a SISO system. The introduction of MIMO has thus a positive influence on the energy efficiency of the considered technologies. The power consumption and coverage model for base stations is then used to develop a prediction tool for power consumption in wireless access networks.
