In Associate in Nursing Ad-hoc network may be a assortment of mobile nodes dynamically forming a short lived network while not the employment of any existing network infrastructure or centralized administer. attributable to restricted communication vary among mobile nodes in ad-hoc network, many network hopes is also required to deliver a packet from one node to a different node within the wire...

Designing a trusted and secure routing solution in an untrustworthy scenario is always a challenging problem. Lack of physical security and low trust levels among nodes in an ad hoc network demands a secure end-to-end route free of any malicious entity. This is particularly challenging when malicious nodes collude with one another to disrupt the network operation. In this paper we have designed...

In multihop wireless systems, such as ad-hoc and sensor networks, the need for cooperation among nodes to relay each other’s packets exposes them to a wide range of security attacks. A particularly devastating attack is known as the wormhole attack, where a malicious node records control and data traffic at one location and tunnels it to a colluding node far away, which replays it locally. This...

A mobile ad hoc network (MANET) is a collection of autonomous nodes that communicate with each other by forming a multi-hop radio network and maintaining connections in a decentralized manner. Security remains a major challenge for these networks due to their features of open medium, dynamically changing topologies, reliance on cooperative algorithms, absence of centralized monitoring points, a...

In Ad hoc On Demand Vector (AODV) routing protocol for Mobile Ad hoc Networks (MANET), malicious nodes can easily disrupt the communication. A malicious node that is not part of any route may launch Denial of Service (DoS) Attack. Also once a route is formed, any node in the route may turn malicious and may refrain from forwarding packets, modify them before forwarding or may even forward to an...

Keywords: Mathematical model Computer networks Malware Anti-malware Stability a b s t r a c t In an era with affluence of local area networks, the recurrent attacks of viruses and other malicious objects are undoubtedly an intruding threat. These malicious objects spread quickly through an unprotected network, corrupt the data and harm the nodes. To comprehend this problem and its plausible sol...

Remotely deployed sensor networks are vulnerable to both physical and electronic security breaches. The sensor nodes, once compromised, can send erroneous data to the base station, thereby possibly compromising network effectiveness. We assume that sensor nodes are organized in a hierarchy and use offline neural network based learning technique to predict the data sensed at any node given the d...
