Security Threats and Defense Approaches in Wireless Sensor Networks: An Overview
Wireless sensor network is emerging technology with their limited energy, computation, and communication capabilities. In contrast of traditional network, wireless sensor networks are deployed in accessible areas, presenting a risk of physical attacks. Sensor networks interact closely with the physical environment because of these reasons current security approaches 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 proper security mechanism. Here, the authors presented different types of security issues in WSN.
