The Internet of Things (IoT) embeds sensors, actuators and computation into everyday 'things' such as lights and thermostats. These things form low-power wireless networks connecting to the Internet via IPv6 for monitoring and control. Such IoT systems are increasingly subject to runtime reconfiguration, wherein new hardware and software may be installed dynamically to accommodate changing application objectives. Supporting runtime reconfiguration, while maintaining reliability and low-power operation requires crosslayer optimisation of network resources. This paper introduces Dawn, a network optimisation approach for component-based systems that automatically extracts and enforces bandwidth requirements from component compositions. Dawn allows application developers to build extremely flexible and yet dependable IoT networks. We implemented a prototype of Dawn for a 50-node testbed composed of state-of-the-art embedded IoT devices. Our evaluation shows that Dawn preserves 100% end-to-end reliability in the face of network reconfiguration, while extending battery lifetime three-fold compared to a onesize-fits-all network configuration with minimal memory and performance overhead.

“…In 2007 the Internet Engineer Task Force (IETF) -the standardization body behind most protocols used in the Internet today -created the 6LoWPAN WG, which defined a compaction and fragmentation mechanism to efficiently transport IPv6 packets in IEEE802.15.4 frames. 2 This simple mechanism allows low-power wireless devices to appear as regular Internet hosts, thereby becoming the "fingers of the Internet." The Internet of Things (IoT) revolution had begun.…”

“…Planning, installing, and maintaining these cables represents a large portion of the cost of ownership of such a wired industrial network. As detailed in this article, advances in reliable wireless technology enable low-power wireless networks to exhibit 99.999% end-to-end reliability and a decade of battery lifetime [2], making them a suitable alternative to wires. This has triggered a trend for industrial networks to "go wireless.…”

Link‐layer security in TSCH networks: effect on slot duration

The IEEE802.15.4e‐2012 standard is widely used in multi‐hop wireless industrial Internet of things applications. In the time‐slotted channel hopping mode, nodes are synchronised, and time is cut into timeslots. A schedule orchestrates all communications, resulting in high reliability and low power operations. A timeslot must be long enough for a node to send a data frame to its neighbour, and for that neighbour to send back an acknowledgement. Shorter timeslots enable higher bandwidth and lower latency, yet the minimal timeslot duration is limited by how long link‐layer security operations take. We evaluate the overhead of link‐layer security in time‐slotted channel hopping networks in terms of minimal timeslot length, memory footprint and energy consumption. We implement full link‐layer security on a range of hardware platforms, exploring different hardware/software implementation strategies. Through an extensive measurement campaign, we quantify the advantage of hardware accelerations for link‐layer security and show how the minimal duration of a timeslot varies between 9 and 88ms for the most common configuration, depending on hardware support. Furthermore, we also highlighted the impact that the timeslot duration has on both high‐level application design and energy consumption. Copyright © 2016 John Wiley & Sons, Ltd.
