Packet Loss Ratio (PLR) is one of the key components for the performance enhancement of a Wireless Sensor Networks (WSNs). This paper investigates the PLR at radio receiver for the different current draw parameters: transmit mode, receive mode, and sleep mode and idle mode keeping other parameters like: initial energy and power supply same for ...
Advanced Encryption Standard (AES), has received significant interest over the past decade due to its performance and security level. Many hardware implementations have been proposed. In most of the previous works sub bytes and inverse sub bytes are implemented using lookup table method and using same key at time in parallel process. This performed less ...
In this paper, the authors explain the preprocessing activities which are performed by the software or language translators before applying mining algorithms on the huge data. Text mining is an important area of data mining and it plays a vital role for extracting useful information from the huge database or data ware house. But before ...
Cloud computing provides huge computing services to the business for improving the organizational growth. Basic requirement needed for this technology is Internet but provides higher capability when compared to the Internet. Cloud computing is a combination of computation, software, data access and also provides storage services. In Cloud, storage of data and the location of ...
Every day, the need for high speed reliable data transmission increases more and more. One important option is the passive optical networks which use the optical fiber and provides high data rates and long distance. This work investigates the performance of a four users Optical Time Division Multiplexing OTDM over different length of single mode ...
This paper is the study of the QPSK (Quadrature Phase Shift keying) modulation technique using AWGN (Additive White Gaussian Noise) and Multipath Rayleigh fading channel. In QPSK scheme the authors can transmit one of the 4 possible signals during each interval of signaling. WCDMA systems are based on higher modulations which provide transmission at higher ...
Wireless sensor network refers to a group of spatially distributed and dedicated sensors for monitoring and recording the physical conditions of environment like temperature, sound, pollution levels, humidity, wind speed with direction and pressure. Sensors are self powered nodes which also possess limited processing capabilities and the nodes communicate wirelessly through a gateway. The capability ...
Rectangular horn is one of the simplest and most widely used microwave antennas. In this paper, an electromagnetic simulator, WIPL-D is used to analyze and optimize the dimensions of the horn antenna which is based on the method of moment’s solution for computations. The standard horn antenna at 10 GHz is modeled and the radiation ...
This paper presents another type of packet sniffer software that captures network data as well as provides sufficient means for the decision making process of an administrator. This paper designed a new model and defined its benefits over existing packet sniffers; the model was developed in Java totally. The aim of this model is to ...
