Reactive security scheme using behavioral aspects of attacks for Wireless Sensor Networks

Wireless Sensor Networks(WSN) are vulnerable to many types of hackers who might get into the network with the intent of fetching its significant data and destroying the network. The sink node in WSN that maintains the database of entire network is also prone to security violations and there is no such security mechanism devised for communicating the data to other nodes. Hence, there is a need to design security scheme with the capabilities to protect the network and the sink node on the occurrence of attack. In this paper, we aim to provide security with a reactive security scheme that includes studying the behavioral aspect of attacks and congregating the security demands. This scheme successively conglomerates the security and the network rescue mechanism free from attacks and their impacts on the network. The simulation results such as Packet Delivery Ratio(PDR), Malicious node activity, Delay, Transmission power depict various attack behaviours in WSN along with the Reception power rate observed by the sink node and the Packet loss.
