Optimal Territorial Resources Placement for Multipurpose Wireless Services Using Genetic Algorithms
(Scientific Research Publishing, 2011-07)
This paper presents a study for finding a solution to the placement of territorial resources for multipurpose wireless services considering also the restrictions imposed by the orography of the territory itself. To solve ...
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 ...
Effect of Changes in Sea-Surface State on Statistical Characteristics of Sea Clutter with X-Band Radar
(Scientific Research Publishing, 2011-07)
We have made observations of X-band radar sea clutter from the sea surface and sea-surface state in the Uraga Suido Traffic Route, which is used by ships entering and leaving Tokyo Bay, and the nearby Daini Kaiho Sea ...
Speed-Sensitive Weighting Algorithm for Digital Beamforming of Adaptive Antenna Arrays
(Scientific Research Publishing, 2011-07)
One of the main objectives of adaptive antenna array processing is reducing the computational complexity and convergence time in a joint state. This article proposes a speed-sensitive adaptive algorithm for estimating the ...
Uniticket: A Third Party Universal E-Ticket System Based on Mobile Phone
(Scientific Research Publishing, 2011-07)
Prepaid energy meters have been widely adopted by utilities in different countries across the world as an innovative solution to the problem of affordability and consumption management. However, the present smart card based ...
Performance Tradeoff with Routing Protocols for Radio Models in Wireless Sensor Networks
(Scientific Research Publishing, 2011-04)
In this paper, we have simulated and evaluated the performance tradeoff with routing protocols: Constrained Flooding, the Real-Time Search and the Adaptive Tree on MICA and MICAz platform with different radio models using ...
Sampling and Reconstruction of Zero-Order Hold Signals by Parallel RC Filters
(Scientific Research Publishing, 2011)
In this work we describe a reconstruction algorithm for zero-order hold (ZOH) waveforms measured by a parallel sam-pling scheme. In the method the ZOH signal is fed to a parallel network consisting of resistor-capacitor ...
Sigma-Point Filters in Robotic Applications
(Scientific Research Publishing, 2015-08)
Sigma-Point Kalman Filters (SPKFs) are popular estimation techniques for high nonlinear system applications. The benefits of using SPKFs include (but not limited to) the following: the easiness of linearizing the nonlinear ...
Hybrid Amplification: An Efficient Scheme for Energy Saving in MIMO Systems
(Scientific Research Publishing, 2012-01)
In this paper, a new amplification scheme for adaptive MIMO systems is proposed and tested. In this ‘hybrid amplification’ configuration, different amplifiers with different peak powers are used. In this way, each transmitter ...
