A Review on Security Challenges and Attacks in Wireless Sensor Networks

Paramjit Kour | Lal Chand Panwar

Abstract: Wireless Sensor Network is emerging technology with their limited energy; computation; and communication capabilities. In contrast to traditional networks; wireless sensor networks are set out in penetrable areas and interact closely with the physical environment; results in increasing the risk of physical attacks; because of these reasons current security mechanisms are inadequate in WSN. In order to facilitate applications that require packet delivery from one or multiple senders to one or multiple receivers must need appropriate security methods. In this paper; we present the review of attacks and security challenges in Wireless sensor networks. First we outline the security constraints; goals; and then attacks with their corresponding prevention and detection mechanisms. At the end we present a comprehensive view of security threats and the layers affected.
