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 ...
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 ...
A Versatile Industrial Timer and Real Time Keeper
(Scientific Research Publishing, 2011-07)
Industrial timer requirements are multifaceted. On-delay, off-delay, cyclic or sequential timing requirements, with usual time range varying from seconds to days, depending on the process. Custom build timers cannot provide ...
Processor for Measuring Radio Network Design Quality
(Scientific Research Publishing, 2011-07)
In this paper we present the design and prototyping of an arithmetic processor based on reconfigurable technology, whose purpose is to determine in a parallel manner the quality of the solution in a radio network design ...
Location Based Performance of WiMAX Network for QoS with Optimal Base Stations (BS)
(Scientific Research Publishing, 2011-07)
In this paper we are given concept of our WiMAX (Worldwide Interoperability for Microwave Access) network perfor-mance for QoS monitoring and optimization solution for BS (Base Station) with multimedia application. In the ...
A New Algorithm of Mobile Node Localization Based on RSSI
(Scientific Research Publishing, 2011-04)
Position mobile node coordinate is a key component to determine the accuracy and efficiency of positioning in wireless sensor networks. Flexible location algorithm admits to adjust the accuracy and time cost of positioning ...
