A Study on Sink Hole attacks in a Wireless Sensor Network

Abstract

Wireless sensor network is a branch of networking that deals with sensing of information from deployed area. Sensor nodes collect the information by sensing and transmit using sink nodes. Sink nodes collects the information from sensor nodes and transmit this information to base station. Transmission of data from sources to destination using various routing and off-demand routing techniques. A sink hole attack is performed on sink nodes, attacking node replaces the actual sink node by advertising its availability and resumes all the data from the sensor node. The actual data is not received at the base station, which results in the loss of the information from the network
