In this paper, we investigate the performance of a fuzzy based Priority Scheduler in wireless Adhoc networks, with real time traffic under varying channel conditions. An Adhoc network is composed of mobile nodes connected by wireless links without any preexisting infrastructure. The network’s dynamic topology poses challenging problems for QoS routing. Hence a scheduling discipline can be used ...

The Mobile Adhoc Networks are more vulnerable because in the (MANET) Network all node works as data sink, transmitter, router. There is no centralized system network, so chances of vulnerabilities very high network. various security issues Network. From attacks flooding most difficult that extremely affect In this paper, a new statistical based technique planned, which used to discover attack a...

The MultiText system retrieves passages, rather than entire documents, that are likely to be relevant to a particular topic. For all runs, we used the reciprocal of the length of each passage as an estimate of its likely relevance and ranked accordingly. For the manual adhoc task we explored the limits of user interaction by judging some 13,000 documents based on retrieved passages. For the aut...

Network simulation tools are commonly used to analyze the performance of Mobile Ad-hoc Networks (MANETS) protocols and their applications. The radio propagation models used for these simulations strongly influence the produced results. While the Two Ray Ground (TRG) model is the most widely used path loss model in reported MANETS performance analysis studies, it is not a realistic model for use...

Many emerging commercial and military applications require secure multicast communication in adhoc environments. Secure multicast communication in mobile adhoc networks is challenging due to its inherent characteristics of infrastructure-less architecture with lack of central authority, high packet loss rates and limited resources such as bandwidth, time and power. Hence key management is the f...

The transmission over wireless network can broadly be classified in two broad categories, as infrastructure wireless network and without infrastructure wireless network. Without Infrastructure wireless network or adhoc network, is an independent system with a certain number of mobile nodes which operate not only as hosts but also as routers. Each node can send and receive data packets, as well ...

The basic philosophy behind Routing in delay tolerant networks (DTNs) is to design routing protocol that maximizes the overall routing efficiency in a network independent of the underlying Transmission and Switching technology & topology for adhoc environment, and the application environment as well. Most designers approach to solve the real world problem by creatively engineering, enabling hig...
