The emergence of nano-electromagnetic communication becomes appealing for potential applications in nano-scale Body Area Network. In this work a new energy aware communication model for nano-electromagnetic communication in Terahertz Band is developed based on clustering scheme for the performance improvement of BAN. The proposed conceptual network model is used to determine channel capacity. A closed-form...
Software testing is one of the most important parts of software development lifecycle. Among various types of software testing approaches structural testing is widely used. Structural testing can be improved largely by traversing all possible code paths of the software. Genetic algorithm is the most used search technique to automate path testing and test case generation. Recently, different novel...
This paper presents an energy aware cluster based architecture where trust aware model is used to improve energy efficiency and spectrum handoff framework is used to reduce handoff rate and thereby improve throughput. The main objectives are trustworthy node selection, cluster head detection, transmission power reduction and increasing successful data transmission by performing handoff. A set of cognitive...
Now-a-days, underwater sensor network (UWSN) technology is becoming more appealing to researchers because it has introduced a new flux in diversified fields like scientific exploration, commercial exploitation, disaster prevention etc. Since, underwater sensor nodes are battery operated, energy is a fundamental design aspect of UWSN's protocol . Besides, low capacity and high propagation delay introduce...
In this paper, we present the performance evaluation of coded wireless ad-hoc network for emergency response communication. Due to the limited transmission range, a number of intermediate relaying nodes may exist between source and destination and these convey source transmission using hybrid Amplify-and-forward (AF)/Decode-and-forward (DF) protocol. All nodes contain single antenna and OFDM based...
Healthcare system can be enhanced vastly with the use of modern information technology. Still now in underdeveloped and developing countries, traditional paper based system is being used in healthcare. Although very few organizations use computer based system, they could not establish a ubiquitous network among patients, physicians and government. Cloud computing is the emerging technology which can...
This paper presents a multi-priority and multi-path selection algorithm for heterogeneous traffic for wireless ad-hoc networks. The main objectives are achieving higher throughput, better resource utilization through load balancing and relinquish network congestion. The proposed algorithm has considered signal-to-interference plus noise ratio (SINR), available link bandwidth, link delay (transmission...
A compact, physical surface potential model for undoped Gate All Around (GAA) MOSFETs has been derived based on a novel analytical solution of the 3-D Poisson equation with the mobile charge term included. The new model is verified by published numerical simulator, Silvaco Device simulator Atlas with close agreement. Applying the newly developed model, the channel potential versus gate voltage characteristics...
In this paper, a VHF air-to-ground multipath propagation channel model is proposed and channel characteristics and BER performance are analyzed. A tapped-delay line filter model with time-varying coefficients is used to model the channel. The taps represent signals with delay corresponding to their relative propagation time. Each delayed signal is modulated in amplitude and phase by independent baseband...
