AODV based Secure Algorithm for Detection and Prevention of Sink Hole Attack in WSN

Wireless sensor network is a branch of networking that deals with sensing of information from deployed area. Sensor nodes collect the information by sensing the information and transmit using sink nodes. Sink nodes collects the information from sensor nodes and transmit this information to base station. In wireless sensor network various malicious nodes has been introduced to perform various types of attacks on the network to degrade or collect same information. The new attack that has been used for acquiring information by performing sinkhole attack. Sink hole attack is performed on sink node attacking node replaces the actual sink node by advertising its availability and resumes all the data from the sensor node. Actual data doesnt receive at base station that loss the information of the network.
