Wireless Sensor Network (WSN) usually consists of a large number of tiny Sensor Nodes (SNs) which are deployed in an operational area for sensing the data, aggregating and processing. This paper emphasizes on safeguarding the hierarchical structure in wireless sensor network by presenting an Intrusion Detection Technique, which is very useful, simple and works effectively in improving and enhancing the security in wireless sensor Network. This IDS works on the combination of anomaly detection algorithm and intrusion detection nodes. Here all the features and numerous architectures of popular IDS(s) along with their confines and benefits are also being described.
