Enhanced Energy Efficient Privacy Provisioning in WSN
Authors: ,
Abstract: Privacy provisioning along with the core functionality of WSN including routing of the sensed data through predetermined optimized routes to the base station which produces pronounced traffic near the sink node adding up to the revelation of either location of direction of location of base station is one of the major research challenges in WSN. The proposed privacy provisioning scheme aims to optimize energy consumption for privacy provisioning in WSN. The traffic patterns may be disguised by introducing fake packets to the generated traffic of original data and a time to live parameter is introduced to execute lesser energy consumption. Earlier also many anti traffic analysis strategies have been proposed and implemented with the same objective But the inclusion of fake packets adds up communication overhead and higher energy consumption in the network as a whole. Hence the problem undertaken in the current research effort is to optimize the energy consumption at the node level for fake packet generation by using residual energy of each node. The energy optimization has been done using the two fold privacy provisioning a) generation of fake packets by the nodes having larger residual energy and avoiding nodes having residual energy less than a threshold value. b) The fake packet generated has an associated TTL (Time to Live) that can be constant or based on the residual energy of nodes.
