A sensor anonymity enhancement scheme based on pseudonym for clustered Wireless Sensor Network

Security problem is an important issue for Wireless Sensor Network. The paper focuses on the privacy protection of WSN applications. An anonymity enhancement tactic based on pseudonym mechanism is presented for clustered Wireless Sensor Network, which provides anonymity for both the sensors within a cluster and the cluster head nodes. Simulation experiments are launched through NS2 platform to validate the anonymity performance. The theoretical analysis and empirical study imply that the proposed scheme based on pseudonym can protect the privacies of both the sensor nodes and the cluster head nodes. The work is valuable and the experimental results are convincible.
