Modules are simple or compound. Simple modules are lowest level of hierarchy and behaviour is programmed in C++. Compound modules are constructed by other simple or compound modules Modules are connected to other modules via gates that send and receive messages that are formed by arbitrary data structures A simulation model is composed by different simple and compound modules, that are interconnected in order to pass messages among them Castalia is a simulator designed for Wireless Sensor Network (WSN) and Body Area Networks (BAN) that are both characterized by low power embedded devices Castalia pre-defines OMNeT++ simple and compound modules to easily simulate WSNs and BANs.

Compound modules are constructed by other simple or compound modules Modules are connected to other modules via gates that send and receive messages that are formed by arbitrary data structures A simulation model is composed by different simple and compound modules, that are interconnected in order to pass messages among them Castalia is a simulator designed for Wireless Sensor Network (WSN) and Body Area Networks (BAN) that are both characterized by low power embedded devices Castalia pre-defines OMNeT++ simple and compound modules to easily simulate WSNs and BANs. Modules might be created or modified to include new protocols or add new applications Guasch, Jaume Security in Smart Cities

Scenario 2. Additional Comments Node 9 has no packets to send since events file had no messages from this node Node 10 does not achieve to send packets to node 0 due to radio congestion at node 4 Node 4 does not receive the packet from node 10 and only forwards packets received from node 5 to next node. When node 10 sends packets to node 4, the radio of node 4 is not ready Node 10 retries sending packet to node 4 according to the defined maximum number of retries and finally discards sending the current packet Congestion in certain nodes has been a big issue not totally solved in order to completely emulate the original network with the supplied event files Adding intermediate nodes has been discarded because no information is available about the existence of any additional nodes in the actual network. Simulations showed that congestion problem prevails or even increases with intermediate nodes Guasch, Jaume Security in Smart Cities

Introduction Background and Related Work Development Analysis and Results Conclusions and Further Work Acknowledgements Initial Results and Improvements Simulation and Output Files Simulation and Output Files Last Development The Final goal was to prepare simulation result files in a convenient format to be used as input in anomaly detectors Detectors will be trained with simulation data coming from several intervals to emulate the real network formed by different nodes from various brands Output files will be the result of simulations run in different scenarios. The objective is to see if the system is able to detect the anomalies when they occur and even classifying the type of attack A single table for every simulation is created containing one row per interval and scenario (no attack, attack of type 1, attack of type 2, etc.) and columns gathering output data about simulation parameters for every node This later analysis is out of the scope of this work. However, the required provisions to compile the CastaliaResults csv file represented the last development of the present work Guasch, Jaume Security in Smart Cities
