Detection and Mitigation of Sinkhole Attack in Wireless Sensor Network

Wireless Sensor Network (WSN) is an emerging technology due to its wide range of applications in public and military area. These sensor networks consisting of thousands of diminutive sensor nodes with limited resources with a base station and low cost, low power sensor nodes that are used for the monitoring purpose. As these sensor nodes are small in size and large in number therefore these networks are easily prone to attack. There can be many possible attacks on sensor network like sinkhole attack, balckhole attack, DOS attack, jamming. Sinkhole attack is among the most destructive routing attack. The issue related to the sinkhole attack is the subverted node or the malicious node advertises the attractive routing information and forces the nodes to route the data towards it and creates a sphere of influence. Therefore sinkhole attack is the kind of attack which degrades the performance of the network. The aim of this paper is to analyze and detect the sinkhole attack in wireless sensor network and to propose the technique to remove this attack to secure the network.
