Ad Hoc Network Hybrid Management Protocol Based on Genetic Classifiers
(Scientific Research Publishing, 2010-10)
The purpose of this paper is to solve the problem of Ad Hoc network routing protocol using a Genetic Algorithm based approach. In particular, the greater reliability and efficiency, in term of duration of communication ...
A New Adaptive EDCA Approach to QoS of Wireless Communications
(Scientific Research Publishing, 2010-07)
Under the background of intelligent transportation application, QoS for various services is different in wireless com-munication. Based on the MAC layer protocol, this paper analyzes the QoS in IEEE 802.11 MAC protocol ...
A Perspective on Traffic Measurement Tools in Wireless Networks
(Scientific Research Publishing, 2010-07)
To understand the characteristics of the wireless networks, the network usage data from wireless measurement tools are essential. The data collection is a process of collecting the network time-varying information in ...
Resonant Length Formulations for Dual Band Slot Cut Equilateral Triangular Microstrip Antennas
(Scientific Research Publishing, 2010-10)
The dual band equilateral triangular microstrip antennas are realized by cutting the slots of either quarter wave or half wave in length, inside the patch. In this design, however these simpler approximations of slot length ...
The Performance Gain of Cognitive Radio in Adaptive Modulation Scheme
(Scientific Research Publishing, 2010-07)
Cognitive radio is considered as one of the main enablers for provisioning dynamic and flexible spectrum/channel allocation in wireless communications. The reliable data transmission over cognitive radio should employ ...
Cognitive Radio Sensing Using Hilbert Huang Transform
(Scientific Research Publishing, 2010-07)
Vast segments of the frequency spectrum are reserved for primary (licensed) users. These legacy users often un-der-utilize their reserved spectrum thus causing bandwidth waste. The unlicensed (secondary) users can take ...
Sensor Placement to Improve the Positioning Performance Based on Angle of Arrival (AOA)
(Scientific Research Publishing, 2010-07)
In this paper, a method for sensor placement to improve the placement quality based on angle of arrival of signal in a specific area is proposed. The installation place of sensors may be constrained with specified boundaries. ...
Performance of Double-Pole Four-Throw Double-Gate RF CMOS Switch in 45-nm Technology
(Scientific Research Publishing, 2010-10)
In this paper, we have investigated the design parameters of RF CMOS switch, which will be used for the wireless tele-communication systems. A double-pole four-throw double-gate radio-frequency complementary-metal-oxide-semicon- ...
WiMAX System Simulation and Performance Analysis under the Influence of Jamming
(Scientific Research Publishing, 2010-07)
This paper presents simulation of WiMAX based system under jamming. The performance of the system was found out to greatly differ with the use of different jamming signals, allowing central areas to be identified, where ...
Design of Aperture Coupled Microstrip Antenna Using Radial Basis Function Networks
(Scientific Research Publishing, 2010-10)
This paper, two Artificial Neural Network (ANN) models using radial basis function (RBF) nets are developed for the design of Aperture Coupled Microstrip Antennas (ACMSA) for different number of design parameters. The ...
