Wireless reprogramming in a Wireless Sensor Network (WSN) is the process of uploading a new code image or relevant commands to sensor nodes or changing the functionality of existing code. As a WSN is usually deployed in hostile environments, so for security reasons every code update must be authenticate to prevent an opponent from installing ...

Basic and heart of all (Digital Signal Processing) DSP are its multiplier. Speed of multiplier determines the speed of the DSP. In DSP, fast multiplication is very important for convolution, Fourier transforms and multiplication is the most basic operation with deep and thorough arithmetic computation. Latency and throughput are two important parameter associated with multiplication ...

Security is the most important part in data communication system, where more randomization in secret keys increases the security as well as complexity of the cryptography algorithms. As a result in recent dates these algorithms are compensating with enormous memory spaces and large execution time on hardware platform. Field Programmable Gate Arrays (FPGAs), provide one ...

In spite of the dramatic growth inside the variability of excellent phones in recent years, the challenge of restricted energy capability of these devices has not been resolved satisfactorily. However, inside the age of cloud computing, the limitation on energy capability is mitigated off in a cheap manner by offloading vital tasks to the cloud. ...

In this paper, the authors present the concept of transmitting power without using wires i.e. transmitting power as magnetic waves from one place to another is in order to reduce the transmission and distribution losses. This concept is known as Resonance Inductive Coupling (RIC). They also discussed the technological developments in Wireless Power Transmission (WPT). ...

In this paper, the authors introduced a 4 bit flash analog to digital converter. The propose ADC consist of the comparators and the MUX based decoder. Propose comparator eliminate the use of resistor ladder in the circuit. All the input of comparators is connected to the common input node. Depending upon the internal voltage of ...

The electricity is very essential in day-to-day life. Most of industries are running with electricity. In commercial areas also electricity plays very vital role and hence electricity is backbone of any developing nation. To measure the consumed electricity and generate electricity bill, the energy meters are provided to each and every consumer. This paper is ...

Addition usually impacts widely the overall performance of digital systems and a crucial arithmetic function. In electronic applications, adders are most widely used. Applications where these are used are multipliers, DSP to execute various algorithms like FFT, FIR and IIR. This paper reports a Conditional Carry Select (CCS) adder circuit with a Successively-Incremented-Carry-Number Block (SICNB) ...

The artificial neural network based technology is playing pivotal role in this highly challenging and unpredictable environment, transcending by nature than ever as far as inclusiveness and sustainability of intelligent and expert system to recognized & satisfy human need is concerned in this competitive arena. In present era Face recognition is widely used due to ...

Most of the existing clustering approaches are applicable to purely numerical or categorical data only, but not the both. In general, it is a nontrivial task to perform clustering on mixed data composed of numerical and categorical attributes because there exist an awkward gap between the similarity metrics for categorical and numerical data. Therefore, this ...
