Wireless sensor network is one of the developing ranges of research in present situation. A Wireless sensor network comprises of geographically dispersed self-governing tiny sensor nodes with little battery life to screen and control over the physical parameters or ecological conditions, for example, temperature, sound, pressure, humidity and so on and this data is gone by the sensor nodes in the network to a next area. Amid transmission, the sensor nodes devour impressive measure of energy. There are numerous requirements on these sensor nodes, for example, constrained memory, restricted battery power, and constrained processing capacity. At the point when sensor nodes send the data to the base station (BS), routing protocols assumes critical part to convey the data at the BS. Low Energy Adaptive Clustering Hierarchy (LEACH) is the surely understood distributed and centralized clustering routing protocol. Wireless Sensor Networks are inclined to different attacks. Black hole a sort of Denial of Service attack is extremely hard to identify and protect. Black Hole attack happens, when a intruder catches and re-programs a set of nodes in the network to block the packets as opposed to sending them towards the base station in wireless sensor network. In this paper, we show the effect of black hole on LEACH protocol researched by the dynamic authors. Likewise we have proposed an algorithm for the identification of the black hole attack.
