An improvised hierarchical black hole detection algorithm in Wireless Sensor Networks

Due to the specific characteristics, Wireless Sensor Networks (WSN) are severely unsafe and are open to malicious attacks. One of the most malicious threats to WSN is in the form of black hole attack that target the routing protocols. This genre of attacks can have a very serious impact on hierarchical routing protocols. A variety of security solutions have been put forth to safeguard WSNs from black hole attacks. However, a majority of the solutions are cumbersome and vitality inefficient. In this paper an improvised hierarchical vitality efficient intrusion detection system is proposed, to protect sensor Network from black hole attacks. Our proposed approach is simple and is based on exchange of control packets between sensor node and base station. The results show that our proposed algorithm is effective in detecting and preventing efficiently the black hole attacks.
