No one could have ever imagined that the immense potential and benefits of creating and using small as well as large networks would also come packed with a hidden factor which would make the network highly vulnerable to the outside world and its miscreants. Networks and the Internet are rapidly expanding sectors of the computing market. Many companies, organizations, and indeed individuals have installed such systems without realizing the risks they are running. This paper examines those risks and their solutions. Since the advent of the Inter ....etc

WISENET is a wireless sensor network that monitors the environmental conditions such as light, temperature, and humidity. This network is comprised of nodes called motes that form an ad-hoc network to transmit this data to a computer that function as a server. The server stores the data in a database where it can later be retrieved and analyzed via a web-based interface. The network works successfully with an implementation of one sensor mote. ....etc

In this technical paper we present a study of the various routing algorithms, which are in use presently. This study of present algorithms is limited to their general working and the various security problems, which they are unable to solve. Our main emphasis is on discussing a novel approach based on Leap-Frog cryptographic signing protocol and that how this novel approach deals the various security threats, which, its predecessors (using traditional public-key signature schemes) are unable to withstand.

Communication methods are essential to enable the continual expansion of the technological society in which we live. They enable people to exchange ideas, opinions and synchronise all interactions between themselves and others. Telephony is still the predominant method of communication although new techniques, such as electronic mail and mobile communications are becoming more and more popular. Network users are requesting increasingly complex services which cannot be effectively supported by existing network architectures. Also, there is a de ....etc

ABSTRACT
The essence of network coding is a paradigm shift to allow coding at intermediate nodes between the source and the receivers in one or multiple communication sessions. The fundamental insight of network coding is that information to be transmitt ....etc

Content Based Multicast Model In Ad Hoc Network

Abstract :

In this model, the content of the multicast data determines the receiver set for the data and the receiver set changes dynamically as the content of the multicast changes. Delivering the multicast to intended receivers while minimizing the message overhead and reducing battery consumption is a challenge made harder because of node mobility. This novel multicast model that distributes this form of threat information in a message efficient manner. In this report, result from detai ....etc

Advance Network-Storage System - SAN & NAS

Abstract :

The storage networking is a dedicated, high-speed network established to directly connect storage peripherals. It allows the direct communication between the storage devices and the client machines on the network. It provides a efficient solution for historical view of server attached storage. The emergence of storage networking brings a new trend in todayâ„¢s networking technology. The two-major components of storage networking are SAN and NAS.
SAN is a storage area network. ....etc

One of the major issues in the networking industry today is tremendous demand for more and more bandwidth. However, with the development of optical networks and the use of Dense Wavelength Division Multiplexing (DWDM) technology, a new and probably, a very crucial milestone is being reached in network evolution. The existing SONET/SDH network architecture is best suited for voice traffic rather than today's high-speed data traffic. To upgrade the system to handle this kind of traffic is very expensive and hence the need for the development of ....etc
