A Comparison of Link Layer Attacks on Wireless Sensor Networks

Wireless Sensor Networks (WSNs) have many potential applications and unique challenges. They usually consist of hundreds or thousands small sensor nodes such as MICA2, which operate autonomously; conditions such as cost, invisible deployment and many application domains, lead to small size and limited resources sensors. WSNs are susceptible to many types of link layer attacks and most of traditional networks security techniques are unusable on WSNs ; due to wireless and shared nature of communication channel, untrusted transmissions, deployment in open environments, unattended nature and limited resources.
