Delay Tolerant Network (DTN) is evolved from Mobile Adhoc Network, MaNet. It is sparse and intermittently connected mobile adhoc network where reliable communication and end-to-end connectivity is not available for message transmission. The end to end connectivity is not ensured in Delay Tolerant Network. Only high latency applications are used in DTN.(More)
An ad-hoc network comprises of mobile nodes that cooperate with each other using wireless connections to route both data and control packets within the network. They are characterized by the use of wireless links, dynamically changing topology, multi-hop connectivity and decentralized routing mechanism and decision-making. The performance of Ad-hoc On(More)
Wireless Sensor Networks (WSNs) are used in many applications in military, environmental, and health-related areas. These applications often include the monitoring of sensitive information such as enemy movement on the battlefield or the location of personnel in a building. Security is important in WSNs. However, WSNs suffer from many constraints, including(More)
Color Visual Cryptography scheme implemented in this paper encrypts informative color image in such a way that result of encryption is in the form of shares. Shares do not reflect any information directly, information is scrambled instead. Each share carries some information which in unreadable by necked eyes. The decryption is done directly by the human(More)

Delay Tolerant Network is emerging and competing research area, in an era where the crowning aim is to provide ubiquitous connectivity, even in diversified regions. In applications of delay tolerant network, secure and energy efficient routing is an important issue in homogeneous and heterogeneous network. Designing a foolproof routing protocol providing(More)
Abstact: The prior communication between the mobile nodes (beacons) in the network is not possible in some situations. As the network topologies and the network traffic conditions vary, the optimum position of the neighbour node should be determined. Localization is one of the fundamental problems in wireless adhoc networks, since locations of the mobile(More)

Delay tolerant network (DTN) is opportunistic network where each node searches best opportunity to deliver the message called bundle to the destination. DTN implements a store and forward message switching system by simply introducing another new protocol layer called the Bundle Layer on top of the transport layer. The bundle layer is responsible for(More)
