A Review on Effective Algorithm to Secure Network Coding Systems against Wormhole Attack

In wireless systems, network coding has demonstrated a powerful approach in expanding system performance. Beside this if we consider the practical scenario, there are numerous security concerns which hinder its wide sending. Other than the very much contemplated pollution attacks, there is another serious risk of wormhole attacks. This attack collapses the execution increase of network coding. As the qualities of network coding are particularly not quite the same as traditional wireless networks. Subsequently the effect of these attacks and countermeasures are obscure. In this paper we analyzed the various techniques to detect as well as prevent wormhole attack and comparison between them. Consequently, we will take a review on centralized algorithm to find wormhole in the network.
