Abstract

Wireless Sensor network is comprised of huge amount of small cost minimal power sensor nodes. The flexibility of wireless sensor networks makes them very attractive to attackers. Wireless sensor networks face resource constraints containing limits on the memory capacity, communication, power and computational power. Also, since they are frequently organized in unfriendly atmospheres and left unattended, they are vulnerable to numerous attacks. One of the major well known and severe attacks in wireless sensor networks is sinkhole attack Sinkhole attacks happen when an affected node attracts network traffic by the advertising fake routing updates. A sinkhole attack targets a sink node. In sinkhole attack a sensor node will consists of a set of false neighbors. Various detection and prevention techniques have been devised but it is still a challenging task. In our proposed work we are detecting as well preventing this severe attacks for that we select two nodes cluster head or boundary nodes. Boundary node behaves as a mediator node for cluster head or base station. Whenever one round completed cluster head and boundary node change.Keywords: Wireless Sensor Network, Attack, AODV, SecurityCite this ArticleSurabhi Tiwari, Dr. Deven Shah.
