En-Route Message Authentication Scheme for Filtering False Data in WSNs

In wireless sensor networks, the adversary can easily control compromised nodes to inject false data reports. En-route filtering is an effective mechanism resist such attacks, where forwarding of reports identify and drop However, existing en-route strategies are vulnerable report disruption attacks selective probabilities efficiencies low. To address these problems, a precheck performed by CoS (Center-of-Stimulus) node presented strategy with balancing residual energy designed message authentication scheme (EMAS) based on monitoring reporting proposed injection attacks. The theoretical analysis simulation results show that in most cases, EMAS provides higher security level probability efficiency very efficient saving.
