Suppose that a data storage service provider implements a functional MSR code based distributed storage system (DSS). Consider a scenario where the service provider has implemented an (n1; k1;B; d1; t1) functional MSR code based DSS, where B is the file that is stored. At a later point of time, due to certain considerations (such as storage cost, download bandwidth to repair failed nodes etc.), the...
Due to the increase in load and use of heavy machines in the industries, the demand for multilevel inverter has been increased to a large extent. This paper investigates the effect of increase in Levels from 3 to 33 levels, using a simplified technique in Separate Source Cascaded Multilevel Inverter (CMlI) on the Total Harmonic Distortion (THD) for 1-Phase and 3-Phase Inverter without using any filters,...

This research paper analyzes the performance of De-Multiplexer (De-Mux) using Pass Transistor Logic Configuration (PTLC) and CMOS Logic Configuration (CLC). Furthermore, a comparison between the performances of both the configurations in terms of power dissipation, chip area, power supply and drive current levels are analyzed. Besides this, paper also signifies more than 50% decrement in interconnect...
In the near future, Vehicular Ad-Hoc Networks(VANET) will help to improve traffic safety and efficiency. Unfortunately, a VANET faced a set of challenges in security, privacy and detection of misbehaving vehicles. In addition to, there is a need to recognize false messages from received messages in VANETs during moving on the road. In this work, the application of Dempster-Shafer theorem (DST) for...
Rai et al. in [1] showed that any rational number p/q is the capacity of some sum-network. The authors proved this result by constructing such sum-networks. The authors first constructed a sum-network with capacity 1/q, and then they connected p of such networks in parallel to create a sum-network of capacity p/q. Such construction requires 2q2 - q number of sources and 2q2-q number of terminals....
In recent years, penetration of renewable energy technologies in electrical power systems have increased the system complexity and therefore require efficient controlling methods to ensure stable operation of the whole system. In present study, the frequency control of autonomous hybrid power system consisting of various generators such as wind turbine generator, diesel engine generator, fuel cell...
This paper presents a practical study on variable frequency, variable load and variable distance of a planar contactless power transfer (CPT) system. The study investigates the behavior of CPT system under three different cases and its characteristics plots are generated for wide range of frequency, load and distance such that the real time situations of CPT systems can be analyzed. With these results...
Ultra Wideband (UWB) technology is a potential technology for short range communication with high data rate and relatively small amount of transmitted power. The coexistence of UWB systems with other narrowband systems make UWB systems prone to interference because of low transmission power limits. In this paper, we propose a technique to mitigate the effect of interference from IEEE 802.11a wireless...
ZigBee is a specification formalized by the IEEE 802.15.4 standard designed for low rate wireless personal area networks (LR-WPAN). It consumes extremely low power for wireless connectivity which allows battery power to sustain for a long time. For routing in ZigBee mesh network, Ad-hoc on Demand Distance Vector (AODV) routing algorithm is extensively used. However the performance of the AODV degrade...
The paper presents mechanism of detection and isolation of sinkhole attack in MANET, substitution of routing protocol to enhance network capability after grievous attack. However, the open shared wireless medium and dynamic nature of MANET makes their routing protocols vulnerable to attacks. First, we analyzed an ad hoc on demand routing protocol over sinkhole attacks. After that use of multi path...
Secure communication is a critical issue in wireless sensor network (WSN). Sensor networks are comprised of a huge number of battery operated general purpose sensor nodes with a small number gateway nodes or base stations. Gateways are more authoritative than ordinary sensor nodes. In this paper, an intensive hashing and symmetric key cryptography based approach is proposed to secure data communication...
Due to large leakage inductance, compensation is usually necessary in contactless system to achieve the required power transfer. A contactless power transfer system is designed with two such compensation topologies and are presented in this paper. Primary compensation is designed to make the primary phase angle equal to the secondary resonant frequency with minimum VA rating of the power supply. Secondary...
If a person or team is not coding friendly, and want to rapidly design and deploy a web based application with dynamic contents, a free and open source software (FOSS) based content based Content Management System(CMS) is choice of millions. The main advantage in using a CMS is that the contents to can be segregated from the design for the application. The content goes to database and design, in the...
Privacy and security are major issues in MANET, especially when used in sensitive areas. Secure routing protocols have been developed/proposed by researchers to provide security and privacy at various levels. ALARM protocol (Anonymous Location Aided Routing in MANET) provides both privacy and security features including confidentiality, authentication and authorization. Location based routing is based...
In Worldwide Interoperability for Microwave Access (WiMAX) host mobility and secure communication is a big challenge due to the unreliable nature of wireless communication. Usually, cryptographic techniques are used for secure communication in networks, it may be wired and wireless. Cryptographic techniques are ineffective if its key management is weak in wireless networks. So, the key management...
