When the network administrator is placed near the LAN, the users will be able to take care of all the activities of LAN. What if the users are to monitor a LAN consisting of hundreds of machines? It is easy to monitor the work of the sub ordinates when the supervisor or manager is in ...

Cybercrime is a complex and ever changing phenomenon. Cyber criminals are becoming more sophisticated and are targeting consumers as well as public and private organizations. Therefore, additional layers of defense are needed. Cybercrime has been increasing in complexity and financial costs since corporations started to utilize computers in the course of doing business. Some of ...

Image processing field is becoming more popular for the security purpose in now-a-days. It has many sub fields and face recognition is one from them. Many techniques have been developed for the face recognition but in this paper, the authors just discussed two prevalent techniques PCA (Principal Component Analysis) and LDA (Linear Discriminant Analysis) and ...

Cloud storage is a model of data storage, whose demand is greatly increasing. The data sharing is one of the concerning functionality in today’s world of information as it involves security, efficiency and flexibility as their important aspects. Various schemes and methodologies are implemented to make data sharing more effective. With the introduction of encryption ...

Uncertain reasoning which is from artificial intelligence community, a unified trust management scheme that enhances the security in MANETs is proposed. In the proposed trust management scheme, the trust model has two components: trust from direct observation and trust from indirect observation. In direct observation from an observer node, the trust value is derived using ...

Wireless Personal Area Networks (WPANs) is an emerging technology for future short range indoor and outdoor multimedia and data centric applications. Two types of WPANs have been standardized by the IEEE 802.15 working group; namely: High data Rate WPANs (HR-WPANs) and Low data Rate WPANs (LR-WPANs). These standards define the network architecture, the physical layer ...

Cryptography is the science of using mathematics to encrypt and decrypt data. Cryptography finds its application in the areas of Wireless Sensor Network (WSN), smart card, identification, and security. With the ever increasing growth of data communication in the field of ecommerce transactions and mobile communication data security has gained utmost importance. However, the conflicting ...

The filter whose response to the impulse signal is bounded, popularly known to be the Finite Impulse Response filter, (shortly an FIR filter) is an important component for designing an efficient digital signal processing system. In different DSP applications FIR filters are widely used. Many applications in digital communication uses the techniques for power reduction ...

The binary adder is the critical element in most digital circuit designs including Digital Signal Processors (DSP) and microprocessor data path units. As such, extensive research continues to be focused on improving the power delay performance of the adder. In VLSI implementations, parallel-prefix adders are known to have the best performance. Binary adders are one ...

The rebellious growth of the mobile application market has made it a significant challenge for the users to find relevant applications in crowded application stores. To diminish this problem, existing solutions often use the user’s application-download history or user-rating to recommend applications that might interest them. However, the user downloading an application does not indicate ...
