MITIGATING HELLO FLOOD ATTACK ON WSN BY LEACH PROTOCOL USING ENERGY LEVEL
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 4, Issue 6
Abstract
Various Wireless sensor network applications use hierarchical routing protocol for routing sensed data to sink. LEACH (Low energy adaptive clustering Hierarchical) is one of the broadly used hierarchical, distributed clustering protocol in WSN. In LEACH, Non - Cluster head Nodes decide to join a cluster head based on Distance between Cluster head and nodes and Received Signal Strength (RSS) of receiving HELLO packets from Cluster head’s making it vulnerable to HELLO Flood attack. In hello flood attack, Adversary node misleadingly claims superior route to the base station (BS) t hereby inviting all the data traffic towards it. HELLO flood attack on LEACH protocol where the cluster head (CH) sends HELLO messages to the non - Cluster Head nodes claiming superior route to base station. The non - Cluster head nodes send the traffic toward s the adversary causing data loss. Hello Flood attack detected the adversarial node in the network by comparing the received signal strength and the distance between with non - CH nodes and cluster head with the threshold values. However, in cases where the non - CH nodes are located closely to the adversary node then the method of threshold RSS and threshold distance will not work properly. The research problem is to discover a new method will work in case where non CH nodes are located closely to the adversa ry node.
