Concealing of the base station's location for preserving privacy in Wireless Sensor Network by mitigating traffic patterns
Pooja Priyadarshini, Manjusha Pandey · 2014
A Wireless Sensor Network (WSN) actually consists of a huge amount of small and tiny individual sensor nodes which are well capable of sensing and collecting data samples from the environment and are treated as the information source. These sensor nodes helps in monitoring physical or environmental conditions and also pass their data samples to the main location through the network. In wireless sensor networks the central point of failure is a base station which collects data from several intermediate nodes. But problem occurs when these intermediate nodes fail to forward the data to the destination node. Attacker examines the packet traffic and can easily reach the base station to destroy it thereby rendering the entire sensor network inoperative. In this paper the proposed privacy preservation mechanism mainly focuses on minimizing the energy consumption thereby increasing the network life time and hence reduces the communication overhead in the network as a whole. Hence our proposed scheme involves generation of fake packets by the nodes considering remaining energy of each node.
