In Vehicular Ad hoc NETworks (VANETs), data dissemination is a challenging task. There are number of techniques, types and protocols available for disseminating the data but in order to preserve limited bandwidth and to disseminate maximum data over networks makes it more challenging. There are broadcasting, multicasting and geo-casting based protocols. Multicasting based protocols are ...

Vehicular Ad-hoc NETwork (VANET) is an ad hoc network of independent nodes moving freely in the network and coordinated by the Road Side Units (RSUs). Each node in the network represents vehicle, for instance car, provided with individual On-Board Unit (OBU) to communicate with other nodes. The nodes move in the dynamic network covering the ...

Many advances have been made in sensor technologies which are as varied as the applications and many more are in progress. It has been reasonable to design and develop small size sensor nodes of low cost and low power. Wireless Sensor Networks (WSNs) are large networks made of a numerous number of sensor nodes with ...

In cognitive radio network, three fundamental tasks are performed by cognitive radio i.e. sensing, learning and reasoning. The importance of learning techniques to be implemented in cognitive radio for the task of learning has been discussed in this paper. Learning techniques for implementation in cognitive radios such as Genetic Algorithms (GAs), Hidden Markov Models (HMMs), ...

The growth of telecommunication leads to the economic growth in manifold for the country. In recent years when the user’s demand has changed significantly, the composition and structure of telecommunication industry has also changed a lot. It directly contributes in GDP, government revenue and employment by lowering transaction costs, by providing faster access of information; ...

As the wireless sensor network are used to bring the interaction in humans, their surrounding and machines to a new level. Wireless sensor network initially used for military purpose ground surveillance, but usefulness of wireless sensor network have gain attention in industries, observing a target in the field, health care applications. Observing the movement of ...

Wireless sensor network contains many heterogeneous or homogeneous tiny sensor devices with limited power resource. The main objective of this sensing device is to collect or gather information from the human unreachable area and deliver the data to the nearest base station. Such devices contain three main components: a sensor, a processor and a wireless ...

Advances in PC and telecom commercial enterprises have made wireless systems progressively well-known and omnipresent. As wireless communication picks up prominence, significant exploration has been dedicated to supporting continuous real time transmission with strict Quality of Service (QoS) necessities for remote wireless applications. In the meantime, a wireless hybrid network that combines a Mobile Ad-hoc ...

QR code is generated with insertion of a color image into it with minimal probability of detection errors. With standard decoding applications these insertions of vital information using QR code into color codes are possible. This insertion takes benefits of the support of QR readers against interruption of image luminance moreover, the vital information in ...

Cipher text-Policy Attribute-Based Encryption (CP-ABE) is an attractive cryptographic approach to the entry manipulates issues. Nonetheless, the situation of enforcing CP-ABE in decentralized DTNs supplies a number of security and alleviation difficulties with respect to the characteristic cancellation, key escrow and synchronization of elements launched from unique regulators. The authors advocate two novel node replicated ...
