Security Against Black Hole Attack In Wireless Sensor Network-A Review

A wireless sensor network consists of geologically distributed autonomous sensors to monitor and control over physical or environmental conditions, like temperature, sound, pressure etc. and this information is passed through sensors in the network to a next location. Military applications was required the development of security in wireless sensor networks. Today such networks are used in many areas like industrial, health, and commercial applications. Black hole attack is occurs, when an intermediary captures and re-programs a set of nodes in the network to block/drop the packets and generates false messages instead of forwarding correct/true information towards the base station in wireless sensor network. Nearby many techniques have been proposed in the literature for detection and prevention of black hole attack in sensor network. There are various solutions proposed in the literature which identifies black hole attack and provides successful delivery of data to the base station. The literature survey showing techniques suffers from very little false positives. Here our paper focuses on review on black hole attack and also elaborates security against black hole attack. We are suggesting some feasible security model to further enhancement to tackling of black hole attack in the wireless sensor network.
