Optimal energy efficiency and power consumption at the base station and user terminal is a prominent problem in 4G networks. In this work, we have examined a power consumption model that evaluates the overall power consumed by two-way communication i.e. power required for the linear processing, the power required for circuit components and power consumed by the Power amplifier. We have also proposed...
Nowadays the spectrum regulations landscape is changing towards more flexible spectrum management schemes, such trends are expected to make additional spectrum resources available and lowers the spectrum access hurdles. In this paper, different spectrum aggregation scenarios have been compared focusing on the tradeoff between the total cost of ownership and the targeted QoS under different market...
This paper discusses the use of Wireless Sensor Networks (WSN) for low data rate and power constrained applications like precision agriculture. Studies of different WSN technologies were conducted and their utility in precision agriculture was evaluated. A ZigBee based sensor node was implemented and field tested. The Sensor Network was also simulated in network simulator (NS2.34) and various network...
With the explosion of wireless communications in number of users and data rates, the reduction of network power consumption becomes more and more critical. This is especially true for base stations which represent a dominant share of the total power in cellular networks. In order to study power reduction techniques, a convenient power model is required, providing estimates of the power consumption...
The power consumption of mobile base stations remains the biggest contributor in the telecommunication networks. RoF has been recognized as a solution to realize energy-efficient base station architecture. In this paper, we investigate the base station power consumption per square meter for five different RoF transmission schemes. Results show that: (1) baseband-over-fiber transmission scheme is the...
Power consumption is an important design criterion in the design of wireless sensor networks. Hybrid radio frequency/free space optical wireless sensor networks (RF/FSO WSN) have been proposed to reduce the energy consumption of traditional RF-based sensor networks. This paper compares the performance of such a hybrid sensor network against the well-known RF-based low energy adapting clustering hierarchy...
Power consumption is an important design consideration for wireless sensor networks (WSNs). Hybrid radio frequency/free space optical (RF/FSO) WSNs have the potential to reduce this power consumption substantially. This paper studies the performance of the RF/FSO WSN by comparing its network lifetime against the lifetime of a traditional RF-only WSN. Two types of networks are considered: reconfiguring...
