Traffic Monitoring and Fault Injection in Wireless Sensor and Actuator networks

When: Wednesday, 2014-Apr-16, 11h30-12h00
Where: FCUL-DI, room C6.3.38
Presenter: Rui Caldeira

Wireless Sensor and Actuator Networks (WSANs) have become an interesting technology for supporting networking communications in different mixed-critical environments, from industrial to aerospace. Such communications are more exposed to errors, and as a consequence, frame transmissions can be subjected to corruption and loss; such loss may cause the necessity of retransmissions, additional traffic loads, unexpected delays, and, as a worst, the deviation of the communication service from its specification (unacceptable for mixed-critical environments). This smalltalk presents an under-development evaluation toolbox able to test and characterize the behavior of IEEE 802.15.4 WSANs under error conditions (emulated by fault injection techniques). This toolbox is based on the Wireshark Network Protocol Analyzer and Commercial Off-The-Shelf (COTS) hardware. Preliminary results will be presented to illustrate its potential and utility.
