The IEEE 802.15.4 standard allows devices to ac- cess the medium not only in contention mode but also in a contention-free way, in order to support Quality of Ser- vice.

This is a particularly insidious form of Denial of Service (DoS) that allows an attacker to thwart QoS while limiting her own ex- posure at the minimum.

Abstract
The IEEE 802.15.4 standard allows devices to ac- cess the medium not only in contention mode but also in a contention-free way, in order to support Quality of Ser- vice. In contention-free mode, devices access the medium according to the Guaranteed Time Slot (GTS) mechanism, which is vulnerable to the selective jamming attack. This is a particularly insidious form of Denial of Service (DoS) that allows an attacker to thwart QoS while limiting her own ex- posure at the minimum. In this paper, we present Selective Jamming Resistant GTS (SJRG), a solution against the GTS- based selective jamming. We also show that our solution is standard compliant and affordable for resource-scarce de- vices like Tmote Sky motes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
