An ME-PC Enhanced HDMR Method for Efficient Statistical Analysis of Multiconductor Transmission Line Networks
An efficient method for statistically characterizing multiconductor transmission line (MTL) networkssubject to a large number of manufacturing uncertainties is presented. The proposed method achieves its efficiency by leveraging a high-dimensional model representation (HDMR) technique that approximates observables (quantities of interest in MTL networks, such as voltages/currents on mission-critical circuits) in terms of iteratively constructed component functions of […]
SCUMG: Secure Code Update for Multicast Group in Wireless Sensor Networks
Securing code update is essential for military and health care applications. The functionalists of the sensor nodes in military and health monitoring region depend on their environmental conditions. The sensor nodes will be divided into different multi cast groups based on their location. For each multi cast group a different code update will be sent. […]
Platform for Multiagent Application Development Incorporating Accurate Communications Modeling
Multiagent systems are widely recognized as a method of choice for realization of distributed time-critical applications for the smart grid. However, no general solutions have been proposed for the difficult task of system development and validation, ready for deployment, which would fully account for the underlying communication network performance. We propose a novel platform designed for this […]
Developing a coherent global view for post disaster situation awareness using opportunistic network
Situational awareness is a critical component in a post-disaster recovery operation for assessment of needs and identification of available resources at different parts of a disaster-affected area. This information, in turn, may help the relief agencies to appropriately coordinate, manage and channelize their resources. A major hindrance in developing such global situational awareness is the […]
Rate, power and carrier-sense threshold coordinated management for high-density IEEE 802.11 networks
Nowadays, trying to obtain better coverage and performance, and allowed by the low-hardware prices, it is common to deploy a large number of IEEE 802.11 devices in offices, meeting rooms or auditoriums configuring the so called high-density networks. In such a scenario, the shared nature of the transmission medium causes interference problems. Some physical-layer- and link-layer-adaptation […]
SDStorage: A Software Defined Storage Experimental Framework
With the rapid growth of data centers and the unprecedented increase in storage demands, the traditional storage control techniques are considered unsuitable to deal with this large volume of data in an efficient manner. The Software Defined Storage (SDStore) comes as a solution for this issue by abstracting the storage control operations from the storage […]
Comparison of heterogeneous network rain fade simulation tools: global integrated network SIMulator and MultiEXCELL
Two heterogeneous network simulation tools are compared and tested against measured data from terrestrial and Earth-space microwave links. Both global integrated network SIMulator (GINSIM) and MultiEXCELL are able to produce joint distributions of rain fade time-series for arbitrary networks of microwave telecommunications links. The tools are fundamentally different in that GINSIM has, as its input, time-series of composite rain rate maps produced […]
High gain Microstrip Antenna design for 2.4GHz WLAN application
IEEE 802.11x standard widely used in wireless local area network systems is called Wi-Fi as well. In this study high gain Microstrip Antenna (MA) design is presented for 2.4 GHz WLAN application. Simulations were made on parameters such as the geometry and size of antennas, type of dielectric material, the thickness of substrate for most appropriate designing […]
Impact of realistic simulation on the evaluation of mobileAd-hoc routing protocols
Today’s advanced simulators facilitate thorough studies on Vehicular Ad-hoc NETworks (VANETs). However the choice of the physical layer and the mobility models in such simulators is a crucial issue that greatly impacts the results. Realistic simulation of routing protocols in VANETs is still an open question. Indeed, only a few works address routing protocols comparison performed under realistic conditions. This paper […]
Development of Real Time Protective Coordination Algorithm for HTS Power Cable
The electrical characteristics of the HTS power cable are dominantly dependent on the property of the HTS wire and cable geometry such as wire twist pitch, cable diameter, gap between the layers, etc. The quench occurs in HTS power cable caused by fault, the resistance appears, the current redistributed, the line impedance between the source […]
