ABSTRACT

Wireless sensor network (WSN) has emerged as one of the most promising technologies for the future. This has been enabled by advances in technology and availability of small, inexpensive, and smart sensors resulting in cost effective and easily deployable WSNs. However, researchers must address a variety of challenges to facilitate the widespread deployment of WSN technology in real-world domains. In this survey, give an overview of wireless sensor networks and their application domains including the challenges that should be addressed in order to push the technology further. In this work, the WSNs are generally deployed in an unattended area, they are prone to various types of attacks. In this scenario, legitimate node shares data to the malicious node and the data are lost. So that it becomes necessary to secure the network from this type of attack. The Intrusion Detection Systems (IDSs) can play an important role in detecting and preventing security attacks. This paper aims to study, discuss and analyze the various techniques for detection of security attack in Wireless Sensor Networks. Also various protocols affected by security attack are studied and analyzed. The existing research methodologies are discussed with their merits and demerits, so that the further research works can be concentrated more.
