Low-power wireless technologies have been applied to industrial fields not only to monitor facilities but also to control them. There is a legitimate requirement to integrate low-power wireless networks with existing IP-enabled networks such as the Internet. The 6LoW-PAN standard makes this happen easily by enabling low-power wireless networks to transport IPv6 packets.A challenge is that an IPv6 packet might not fit in a link-layer frame. The answer is fragmentation: the IPv6 packet is cut into fragments, each fitting in a frame. In a typical implementation, the IPv6 packet is fragmented and reassembled at every hop. Such perhop reassembly causes low end-to-end reliability and high end-to-end latency. This article presents a new implementation technique which results in fragment forwarding without changing any of the standards. Simulation results show how, when going from per-hop reassembly to fragment forwarding, end-to-end reliability goes from 40% to 100%, memory requirements go from 1280 B to 160 B, and end-to-end latency is halved. * Y Tanaka, P.

“…Our simulation campaign relies on the 6TiSCH Simulator [27] that was created as part of the standardization activity, and which has been used extensively by the 6tisch working group. Our simulation study involves two nodes trying to communicate while an attacker is trying to selectively jam the radio channels.…”

“…The slotframe consists in 101 timeslots whose duration is 15 ms each. The packet delivery ratio over the link varies over time, in accordance with the Pister-Hack model [27]. Considered wireless links are configured with a minimum packet delivery ratio of 0.95, in order to clearly identify the impact of attacks.…”

Numerous medium access control (MAC) have been proposed for Low-power Lossy Networks (LLNs) over the recent years. They aim at ensuring both energy efficiency and robustness of the communication transmissions. Nowadays, we observe deployments of LLNs for potentially critical application scenarios (e.g., plant monitoring, building automation), which require both determinism and security guarantees. They involve battery-powered devices which communicate over lossy wireless links. Radio interfaces are turned off by a node as soon as no traffic is to be sent or relayed. Denial-of-sleep attacks consist in exhausting the devices by forcing them to keep their radio on. We here focus on jamming attacks whose impact can be mitigated by approaches such as time-division and channel hopping techniques. We use the IEEE 802.15.4e standard to show that such approaches manage to be resistant to basic jamming but yet remain vulnerable to selective jamming. We discuss the potential impacts of such onslaughts, depending on the knowledge gained by the attacker, and to what extent envisioned protections may allow jamming attacks to be handled at upper layers.
