The central challenge in the design of ad-hoc networks is the development of dynamic routing protocol that efficiently finds route between mobile nodes. Several routing protocols such as DSR, AODV and DSDV have been proposed in the literature to facilitate communication in such dynamically changing network topology. In this paper, a Node Transition(More)
In this paper, we study the effect of routing protocols on the performance of Media Access Control (MAC) protocols in Mobile Ad hoc Networks (MANET). Three well known MAC protocols such as 802.11, Carrier Sense Multiple Access (CSMA) and Multiple Access with Collision Avoidance (MACA) are considered for performance study. The main focus of this paper was to(More)
Wireless Sensor Networks consist of small nodes with sensing, computation and communication capabilities, often deployed in remote inaccessible areas to interact with the environment and forward the measured event to the base station, thus posing several possibilities of physical attacks. Hence security becomes an important issue in wireless sensor(More)
In this paper, we propose a unanimous & distributed-intrusion detection model for mobile ad hoc networks. The MANETS are particularly vulnerable to intrusion, as they operate in the open medium and use co-operative strategies for network communications. This paper is mainly to identify the misbehaviors caused by some malicious node for reactive routing(More)
WVSN is a collective network of motes containing visual sensors. The nodes in the network are capable of acquiring, compressing, and transmitting successive images to the sink. To increase the lifetime of such network, it is essential to reduce the amount of dataflow across the network without losing the integrity. This paper proposes a CS-based image(More)
