An efficient fuzzy-based power control scheme for ad hoc networks

2015 Wireless Telecommunications Symposium (WTS), 2015
Pervasive computing devices frequently rely upon wireless ad hoc connections to exchange information with neighboring systems. The density of these types of wireless transactions will steadily increase as the Internet of Things (IoT) expands. To mitigate the growing demand for wireless bandwidth, the available frequency bands can be more effectively ...

Efficient interference-aware power control in wireless ad hoc networks

2017 IEEE International Conference on Communications (ICC), 2017
Interference management through power control in wireless ad hoc networks has both the hidden terminal problem which induces collisions, and the exposed terminal problem which prohibits concurrent transmissions. Both problems are caused by the varied interference range induced by the adjusted transmission power.

Power-ef?cient gossiping in multi-hop ad hoc networks

Proceedings of the 2nd International ICST Conference on Autonomic Computing and Communication Systems, 2008
In this paper, we present a novel gossiping protocol for disseminating information in static and mobile multi-hop ad hoc networks. Our protocol exhibits two interesting properties. First, it tends to decrease the power required to disseminate information, by reducing the transmission range each network node uses for gossiping.

Power Aware Cluster Efficient Routing in Wireless Ad Hoc Networks

2005
In Ad Hoc networks a routing protocol is either proactive or reactive. The former maintains consistent up-to-date routing information from each node to every other node in the network, whereas the latter creates route to the destination only when desired by the source node using “flooding”. In flooding packets are broadcast to all destinations with the

Influence of output impedance on power added efficiency of Si-bipolar power transistors

2000 IEEE MTT-S International Microwave Symposium Digest (Cat. No.00CH37017), 2002
The power added efficiency (PAE) of low voltage RF bipolar power transistors for cellular applications, is carefully analyzed experimentally and theoretically. We found that the transistor with low output capacitance operates in "inverse class AB", which facilitates high efficiencies.

Design of 60 Ghz CMOS power amplifier to improve power added efficiency

2017 International Conference on Smart grids, Power and Advanced Control Engineering (ICSPACE), 2017
This discourse used 45nm CMOS technology to model a power amplifier of class AB for a Power Added Efficiency (PAE) of 23% and power gain of lOdB at the 60GHz unlicensed band of frequency. This CMOS class-AB Power Amplifier (PA) is one of the important stages to enhance the power output of the transmitter chain.

An efficient flooding method in ad-hoc networks for reducing power consumption

2008 IEEE International Conference on Systems, Man and Cybernetics, 2008
In recent years, improved performance of wireless communication technology and lighter mobile terminals that have advanced functions have encouraged consideration of ad-hoc networks, which are temporary networks for the exchange of information among mobile wireless terminals.

A 3.1-GHz Class-F Power Amplifier With 82% Power-Added-Efficiency

IEEE Microwave and Wireless Components Letters, 2013
This letter presents the first high-frequency, multi-harmonic-controlled (> 3), Class-F power amplifier (PA) implemented with a packaged GaN transistor. For PA design at high frequencies, parasitics of a packaged transistor significantly increase the difficulty of harmonic manipulation, compared to low-frequency cases.

Efficient Power Utilization in Multi-radio Wireless Ad Hoc Networks

2009
Short-range wireless communication capabilities enable the creation of ad hoc networks between devices such as smart-phones or sensors, spanning, e.g., an entire high-school or a small university campus. This paper is motivated by the proliferation of devices equipped with multiple such capabilities, e.g., Blue-Tooth (BT) and WiFi for smart-phones, or ...
