A NOVEL SURVEY ON LOCATION BASED NODE DETECTION AND IDENTIFYING THE MALICIOUS ACTIVITY OF NODES IN SENSOR NETWORKS

In sensor network node detection plays an important role in many applications. In this report, we are proceeding to go over the methodologies for the node detection based on the position. Likewise, we will survey on how the node will be detected based on different methodologies like distance vector, GPS, etc., Even though the nodes are called up. We also perform surveys on identifying the malicious activity of guests in a sensor network, like wormhole attack. In this paper localization is protected by detecting compromised beacon nodes. Methods adopted are very simple yet effective, and efficiency is guaranteed within the constraints of a sensor's battery life and limited memory. The aims of this paper are reliable communication, cooperative network, expanding of a network and shrinking of the net. The work includes an RSSI technique for locating the situation of the Wi-Fi enabled nodes and determining the variance in the intensity of the signal at individual nodes connected to an admission point, as the number of nodes increases or reductions.
