Mesh routing is difficult, mesh routing for low power and lossy networks is straight up comatose. This session will help understand how the signalling/messaging works and depict sample packet captures for RPL signalling from real environments. It will also introduce tools apart from wireshark, such as scapy that can help construct/deconstruct the messaging. Obtaining performance […]

IPv6 ND was designed for P2P and transit subnetworks with cheap and reliable broadcast capabilities. This session will explain how this is unfit with IoT wireless operation, and explain the operation of SFAAC (stateful address autoconfiguration) that was introduced with 6LoWPAN ND. The talk will discuss how SFAAC interacts with RPL and proxy ND to […]

RPL, the IETF standard for routing in low power lossy networks, was designed to meet unusual constraints in terms of scale (high), device capabilities (limited), and link reliability and capacity (very low). To meet those constraints, RFC 6550 introduced a number of innovations with the use of anisotropic routing, stretched P2P path, autonomic properties, objective […]

In this IPv6 and 6LoWPAN Webinar, a detailed overview of the 6LoWPAN Adaptation layer will be given. Indeed, this webinar is dedicated on how 6LoWPAN enables to use of IPv6 over IEEE Std 802.15.4 networks. During this webinar, the following three objectives will be covered: First, the principles of IPv6 Header Format overview will be […]

Despite the general benefits experienced with converging data, mail, voice, and video over IP, a number of domains in Operational Technology (OT) including Industrial IoT, vehicular automation, professional audio, and so on, still rely on semi-proprietary technologies for their the network operations. This is because machine-to-machine communications require deterministic properties such as guaranteed worst case […]

Microcontrollers have enabled adding processing and communication to many physical objects, but the result is not a simple copy of a general-purpose computing environment. Bringing these objects into the Internet requires attention to their specific constraints. Since 2005, the Internet Engineering Task Force (IETF) has been shaping Internet protocols towards the special requirements of such […]
