Detection Of Black Hole, Gray Hole, Misdirection And Dos Attack In WSN

Wireless Sensor Network (WSN) its an large network.WSN are very popular and have their special individuality such as limited battery, power and storage which makes the energy consumption. Although there are some limitations but there are many compensation of Wireless Sensor Networks. Some compensation are robustness, scalability, flexibility. WSN also reduces the electric wiring cost. Now a days WSN is mostly used in modern technologies to gain the output in most competent way. Some applications of WSN are area monitoring, health care monitoring. In this paper we are detecting black hole attack, gray hole attack, misdirection attack and DOS attack in WSN. Keywords— Wireless Sensor Network , Black hole Attack , Gray Hole Attack , Misdirection Attack and DOS.
