Trust management in WSN – a case study

Janusz Górski, Alan Turower


The paper presents a case study related to application of WSN to supporting a patient with overweight in his/her home environment. It was assumed that the network implements a method of distributed trust management and is was demonstrated that this method provides for detection and isolation of sensors violating the network policies. Quantitative estimates of time necessary to detect such malicious nodes were obtained with the help of a dedicated network simulator. In conclusion we identified problems which will be further investigated, targeting at improvement and assessment of the proposed trust management method.
