Anonymous Secure Reputation Routing System For Selective Forwarding Attacks In Wireless Sensor Networks

Abstract

Wireless Sensor Networks (WSNs) are more vulnerable to various security threats. One of the
most important threat is selective forwarding attacks which maliciously drop a subset of packets
which are being forwarded hence it makes the resource unavailable to its intended users. Due to
this drop the packet loss rate is high and hence it poses a great challenge to differentiate
between the normal loss and the malicious drop. In this paper, an anonymous secure routing and
reputation system which detects the compromised nodes are combined where the malicious drop
can be identified and reduced. Simulation results demonstrate that anonymous secure reputation
routing system is more efficient than the reputation system. Further this type of authenticated
secure routing improves the data delivery ratio of the network.
