A Threat Model Approach for Classification of Network Layer Attacks in WSN
Wireless Sensor Networks (WSN) comprise an emerging technology which has received a significant attention from the research community. Several small and low cost devices are included in the sensor networks which are self organizing ad hoc systems. WSNs are susceptible to many types of attacks at various layers of networks but due to limited resources most of traditional networks security techniques are unusable on WSNs. Hence security is a vital requirement for these networks. In this paper, the focus is on security of WSNs. A threat model has been considered; divided into four parts and has been used for evaluation of security at various layers of WSN.
