A simulation tool for security attack evaluation in WSN

The presence of Wireless Sensor Networks (WSNs) in the common life and their applications field (e.g. medical, environment monitoring etc) can make them subject to security attacks, thus is important to providing them with security mechanisms. Due the limited resources of a WSN and the increasing number of attacks available is quite difficult furnish a countermeasure for each of them without affecting the performance of the network. Instead is useful to know which are the attacks that cause the most high effects and provide the countermeasures to the network. In this work I present an implementation for Castalia simulator of the framework AFS (Attack Framework Simulator) that allow the users to define, one or more, attacks and evaluate their effects on a network
