In this paper, we propose an energy-efficient location-aware clone detection protocol in densely
deployed WSNs, which can guarantee successful clone attack detection and maintain satisfactory network
lifetime. Specifically, we exploit the location information of sensors and randomly select witnesses located in a
ring area to verify the legitimacy of sensors and to report detected clone attacks. The ring structure facilitates
energy-efficient data forwarding along the path towards the witnesses and the sink. We theoretically prove that
the proposed protocol can achieve 100 per cent clone detection probability with trustful witnesses. It is easy for
adversaries to mount node replication attacks due to the unattended nature of wireless sensor networks. In
several replica node detection schemes, witness nodes fail to work before replicas are detected due to the lack of
effective random verification. Our scheme distributes node location information to multiple randomly selected
cells and then linear-multicasts the information for verification from the localized cells. Simulation results show
that the proposed protocol improves detection efficiency compared with various existing protocols and prolongs
the lifetime of the overall network. Extensive simulations demonstrate that our proposed protocol can achieve
long network lifetime by effectively distributing the traffic load across the network.
