Geographical information based false report filtering scheme in wireless sensor networks

Abstract

A geographical information based false reports filtering scheme(GFFS)in sensor networks was presented.In GFFS,each node distributes its location information to some other nodes after deployment.When a report was generated for an observed event,it must carry not only MACs from t detecting nodes with distinct key partitions,but also locations of these nodes.Each forwarding node checks not only the correctness of the MAC and the locations carried in the report,but also the legitimacy of the locations.Analysis and simulation results demonstrate that GFFS can resist collaborative false data injection attacks and thus can tolerate much more compromised nodes than existing schemes.
