Storage nodes play a vital role in wireless sensor networks for carrying out the storage activity of data sent by the sensor node once after capturing the details of the environment and in turn to answer the sensor data related query to the network owner. Because of the less storage capacity on the sensor node, storage node takes the whole responsibility for pre-processing the data as well as to respond to queries returned by the owner. Duplicate sensor/storage node imposes a major threat to the wireless sensor networks. The proposed approach focusses on carrying out the effective techniques for data transfer by using Elliptic Curve Encryption for encrypting the image captured from the environment and also to transmit the encrypted critical text data from source to destination, aggregate Signature to validate the sender of the message for data verification, steganography to hide the encrypted content within an image. The proposed ideas are well suited for transferring the details secure in WSN.Keywords

Vehicular Ad hoc Network (VANET) is a subset of Mobile Ad hoc Network (MANET). VANET is a self-organized information system composed of vehicles (and possibly additional infrastructure) capable of short-range communication through the device called On Board Unit (OBU). There is a wide range of possible application areas of VANETs, including warning systems, collision avoidance/notification, autonomous vehicles, and traffic optimization.
VANETs rely heavily on broadcast transmission. When a vehicle rebroadcasts a message, it is highly likely that the neighboring vehicles have already received it, and these results in a large number of redundant messages. This affects inter-vehicle communications, since redundant rebroadcasts, contention and collisions can be largely increased as the number of vehicles increases. Broadcasting packets may lead to frequent contention and collisions in transmission among neighboring vehicles this problem is referred as the broadcast storm problem.
The main goal of Selective Reliable Broadcast protocol (SRB), is intended to limit the number of packet transmissions. Through an opportunistic vehicle selection, packets are retransmitted towards a next hop, in order to strongly reduce the number of forwarder vehicles, while preserving an acceptable level of QoS. SRB belongs to the class of broadcast protocols, as well as cluster-based approaches. It exploits the partitioning behavior, as typical from vehicular ad hoc networks, in order to automatically detect vehicular clusters, intended as “zones of interest”. Packets will be then forwarded only to selected vehicles, opportunistically elected as cluster-heads. SRB performances have been assessed in different vehicular scenarios, mostly realistic environments, such as highway scenarios.

Pumpkin seed, grape seed, pomegranate peel and orange peel were dried in shadow powdered and it was incorporated in different traditional breakfast items such as idli, dosa, sevai, puttu and chapathi in three different variations 5%, 10% and 15%. Sensory analysis revealed that 5% level incorporation was the most acceptable proportion in all the breakfast recipes. The nutrient analysis showed that the powdered peel and seed were rich in Vitamin C, E and β-carotene. The microbial study was also carried out till 15 days and the results showed that there were no microbial growth in the prepared powders and it was concluded that they were safe for consumption.
