Abstract

Abstract: Wireless sensor networks can be deployed in harsh environments for monitoring purposes. In such environments where there is a lack of human presence, the network may face severe security and privacy issues due to unauthorized access of a powerful attacker. The attacker may exploit the contextual information to locate the position of the asset. We propose a scheme for protecting the location of the source node, which consumes less energy hence maximizing network lifetime. The proposed scheme has the inspiration of black and white regions of the chessboard, which represent sleep and active regions in the wireless sensor network. This alternation plays its role in reducing the total energy consumption along misguiding the eavesdropper from finding the source node location. Our scheme uses dynamic cluster head selection to further add to location privacy. The results show that we have improved the safety period by a maximum of 131% and a minimum of 17% than that of the compared techniques. Similarly, a maximum of 60% reduction in energy consumption and a 20% reduction in latency is recorded by our proposed scheme. These results make our scheme suitable for application requiring high‐safety period along maximizing network lifetime. Abstract : The proposed technique EeSP provides Source Location Privacy in monitoring‐based applications. It consumes less energy, hence maximizing network lifetime. The network is divided into alternate active and sleep areas inspired from the black and white regions of the chessboard. This alternation plays its role in reducing the total energy consumption along misguiding the attacker from finding the source node location.
