The paper is an effort to build an energy efficient mechanism which can preserve the privacy of the location of base station and the source nodes so that the adversary cannot take down these nodes. Core functionality of WSN includes routing of the sensed data through predetermined optimized routes to the base station thus producing pronounced traffic near the sink node adding up to the revelation of either location of direction of location of base station. To overcome this revelation of base station the traffic patterns may be disguised by introducing fake packets to the generated traffic of original data. Many anti traffic analysis strategies have been proposed and implements with the objective of attaining traffic uniformity in network.
