Due to the particular characteristics, wireless sensor network (WSN) is severely unsafe and are receptive malicious attacks. One amongst the foremost malicious threats to WSN is within the sort of part attack that focuses on the routing protocols. This genre of attacks will have an awfully serious impact on ranked routing protocols. A range of security solutions is place forth to safeguard WSNs from part attacks. However, a majority of the solutions are cumbersome and vitality inefficient. During this paper, an jury-rigged classified energy efficient black hole detection & interference model is planned to guard device network from part attacks. Our planned approach is straightforward and relies on reserve path choice between device node and base station. The results show that our planned algorithmic program is effective in detection and preventing with efficiency the part attacks.
