ABSTRACT:This paper proposes a new approach for cluster based routing algorithm for hybrid mobility model to regulating the vehicular traffic. Our approach uses a new hybrid mobility model combining randomwaypoint and group mobility model using static and dynamic sources and a novel cluster based routing algorithm. To transmit the real time updated information and maintain long link duration to improve the data delivery ratio, we propose Location based Multipath Flooding (LMF) algorithm, which is suitable for vehicles with variable mobility. The scenario and the network are modeled and investigated through extensive simulations using Ns2 simulator to study the performance in terms of cluster construction.

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 focuses 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, stenography to hide the encrypted content within an image. The proposed ideas are well suited for transferring the details secure in WSN.
