Black Hole Detection Scheme in WSN forMobile Replica Node Detection and Rejection

[摘要] Security of wireless sensor network is a major concern in military, business and environmental applications. The replica nodes are controlled by the adversary, but have keying materials that allow them to behave like authorized participants in the network. Sequential Probability Ratio Test (SPRT) uses the fact that an uncompromised mobile node should never move at speed in excess of the system-configured maximum speed and it fails when the replica nodes fails to provide signed location and time information for speed measurement. This is overcome by employing a quarantine defense technique to block non complaint nodes. Black hole detection technique can be implemented, thereby enabling the effective detection of static and mobile replica nodes. This is realized using Network Simutator-2.
