Networking Protocols for Internet of Thingsrjain51
This document discusses networking protocols for internet of things (IoT) devices, focusing on 6LoWPAN and RPL. 6LoWPAN is described as adapting IPv6 for use over IEEE 802.15.4 low-power wireless networks through header compression and new addressing schemes. RPL is introduced as the routing protocol for low-power and lossy networks, using a directed acyclic graph structure to route packets towards a root node in a way that optimizes objectives like energy efficiency. Key concepts for both protocols like addressing formats, header types, and control messages are outlined at a high level.
O-RAN is an approach to making radio access networks more open and interoperable. It uses open source software, standardized interfaces, and general purpose hardware to allow for innovation and flexibility compared to traditional monolithic and proprietary systems. The high-level design involves splitting the network functions into different units like Distributed Units and Centralized Units that can be deployed in various locations like at the edge of the network or in centralized data centers. Key use cases focus on allowing telecom operators to innovate and improve their networks as well as enabling new applications that require low latency edge computing capabilities.
Mobile operators across the globe have already started to roll out their 5G. It is here to stay and so security should be kept it mind ensuring the industry learns from the lessons of previous generous networks.
In 2020 our PT Telecom Attack Discovery (PT TAD) 5G-ready next-generation signaling firewall scored no. 1 on the security market.* Want to find out the reasons behind this accolade, then watch the record of our webinar to learn about an effective approach towards signaling security in the era of 5G.

5G is designed to serve an unprecedented range of capabilities with a single global standard. With enhanced mobile broadband (eMBB), massive IoT (mIoT), and mission-critical IoT, the three pillars of 5G represent extremes in performance and associated complexity. For IoT services, NB-IoT and eMTC devices prioritize low power consumption and the lowest complexity for wide-area deployments (LPWA), while enhanced ultra-reliable, low-latency communication (eURLLC), along with time-sensitive networking (TSN), delivers the most stringent use case requirements. But there exists an opportunity to more efficiently address a broad range of mid-tier applications with capabilities ranging between these extremes.

Energy consumption study of a WSN using 6TiSCH architectureFederico Sismondi
Motivated by the active developments on the industrial automated world and the new technologies arising in the
area of Internet of Things, the IETF, based on IEEE’s existing standards, and some already accepted protocols,
propose a new architecture to satisfy the needs of both fields.
6tisch, the new IETF’s architecture to be studied during our project, aims to give a convergent solution for both
fields that have plenty of common points. It aims to satisfy the requirements of the wireless low powered lossy networks. Among them, we can point out: energy management policy, energy efficient design, link reliability,
robustness, scalability support, interoperability, self organization, end to end reliability, security and mobility
support, as the most noticeable ones.
The project proposed aims to obtain a well founded experience on how the newly developed architecture 6tisch performs in the OpenWSN project. The partner enterprise wants to quantify the energy consumed by the motes in a real use case, with special detail on how the different parameterizations of the protocol stack would affect it.
Due to the increasing need of networks relying on low energy consumption, our project will analyze from the
lowest layers of the protocol stack how 6tish architecture performs energywise and how the different mechanisms like routing table construction, message forwarding function, scheduling of the TSCH slots, and many others will perform.
The document discusses the Time Synchronized Channel Hopping (TSCH) mode of the IEEE 802.15.4e standard for low-power and lossy networks. It provides an overview of how TSCH enables deterministic communication through time synchronization, channel hopping, and scheduled transmissions. It also outlines the role of the ROLL working group in developing an architecture that integrates 6LoWPAN, RPL, and other standards with the TSCH mode at the MAC layer to provide IPv6 connectivity over low-power and lossy networks.
This document discusses IEEE 802.15.4 and Zigbee wireless communication standards. It provides an overview of 802.15.4, including its applications, characteristics, frequency bands, and MAC and PHY specifications. It also describes Zigbee's architecture and how it works with 802.15.4 at higher protocol layers to provide networking and routing functionality. Typical network topologies for 802.15.4 like star, peer-to-peer, and combined are also covered.
The document discusses the fringe of the Internet, which includes low power lossy networks (LLNs) connected by radio links. It describes characteristics of LLNs like highly constrained devices, small frame sizes, and energy efficiency requirements. The routing protocol for LLNs needs to be adapted to these types of links. The document outlines different approaches for connecting LLNs to the Internet, including mesh under, route over, and overlay models. It introduces RPL as an IETF routing protocol designed for routing over radio in LLNs.
The document describes the oLAF algorithm for building Available Routing Constructs (ARCs) in a network. oLAF is a variation of the SPF algorithm that creates ARCs by connecting shortest path trees. It identifies mono-connected zones in the network and provides redundancy within these zones by forming ARCs. The algorithm works by picking nodes in order of closest to the root and building dependent sets for each node to form ARCs between safe nodes that have multiple paths to different parts of the network. This allows traffic to be rerouted within ARCs in the event of failures while avoiding forwarding loops.
The document discusses the evolution of wireless networks and the emergence of the "fringe" of the internet. The fringe consists of wireless networks that extend the reach of the internet in a decentralized manner using various protocols and technologies. Key aspects of the fringe discussed include the route-over fringe using protocols like RPL to allow devices to route over multi-hop topologies, the mesh-under fringe using technologies like ISA100 for industrial wireless sensor networks, and the RPL fringe protocol used to route in low-power and lossy networks.
Towards the Internet of Relevant Things: the IEEE 802.15.4e StandardGiuseppe Anastasi
The document discusses the IEEE 802.15.4 standard and its limitations for Internet of Things applications with stringent requirements. It introduces the IEEE 802.15.4e standard, which amends 802.15.4 to add two new MAC modes - DSME and TSCH. DSME aims to provide bounded latency while TSCH uses channel hopping to improve reliability. The document surveys the literature on both new modes and discusses open issues and how 802.15.4e can help realize the vision of the Internet of Things.
CU Alliance RPL e-Portfolio_Assessment Tool Gavin Clinch
Recognition of Prior Learning (RPL) is the generic term for learning assessment mechanisms such as Accreditation of Prior Learning (APL) or Advanced Academic Standing, which are used within Higher Education Institutions to describe the awarding of credit/exemptions to applicants on the basis of demonstrated learning that has occurred prior to admission.
The OECD (2008, p.50) reported that ‘demand for RPL is latent in Ireland and once employers and workers are well informed about RPL, interest is generally high’. Furthermore, Hunt (2011, p.55) stated that ‘RPL is particularly important as flexible and workplace learning opportunities expand. A national framework for RPL must be developed, based on the expertise and experience already built up in the higher education institutions. Progress in this regard will help to shift the emphasis from educational inputs towards learning outcomes. This student-centred philosophy lies at the heart of the National Framework of Qualifications (NFQ).’
The Connacht Ulster Alliance (GMIT, IT Sligo and LYIT) initiated a project to inform, support and facilitate Irish or international applicants in applying for RPL to gain entry onto a programme or seek exemptions from parts of a programme.
A dedicated web portal (www.myexperience.ie) was created to provide relevant information on RPL through short videos and text. The website defines the different mechanism of RPL assessment, provides details on the process and links to the CUA e-Portfolio tool. The actual e-Portfolio tool was created in Moodle 2.6 as this provides for assessment of learning. As a paperless tool, it provides an electronic submission of evidence and allows the learner to submit their portfolio in a sequence of stages resulting in the creation of a professional RPL portfolio. The e-Portfolio of evidence includes: certified learning; experiential learning; references; work experience outputs and motivational statements.
The CUA e-Portfolio will be piloted from May to August 2014 in GMIT, LYIT and IT Sligo. This tool offers a national solution for RPL applicants and has the potential to provide for digital badges.

IRJET- Dynamic Adaption of DCF and PCF Mode of IEEE 802.11 WLANIRJET Journal
This document discusses dynamic adaptation of the Distributed Coordinating Function (DCF) and Point Coordinating Function (PCF) modes of the IEEE 802.11 WLAN standard. It proposes three protocols to dynamically switch between the DCF and PCF modes based on changing traffic load and network size. One protocol is a Dynamic Switching Protocol that observes network traffic to determine when to switch modes. A second protocol, Priority Round Robin Scheduling, aims to reduce polling overhead in PCF by replacing simple round robin scheduling with priority-based scheduling. The document also discusses dynamically adapting configuration parameters in PCF and DCF based on varying network conditions.

How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
So let’s take a look at the characteristics on an LLN. What is it that makes an LLNAs mentioned before the devices are highly constrained, so we need to keep the state in each device to a minimum – for example we would not want the entire Link State database in every SensorIt is critical than an LLN uses the minimum amount of energyThere is a various array of traffic patterns - multipoint and point2pointProbably the most important thing to note is LLNs operate over networks with very restricted frame sizesWe can’t have giant packets running over poor quality linksThe routing protocol has to be really efficient – we can’t have it catering for every event/situation possible.
Wespeak of iot but most of the time thisisreally about ITOT, thatis the integrationof OT and IT.Benefits of convergence. 40 yearsago, OT = OsTralia. In convergence isindustrialthat’scalled indus internet.Cheerscale => IPv6Evolution thatis happening. Eg HART-IP . Startingnaturally in the plant net, then control net thendevices. We are creating a cross fire to accelerate the adoption.130 millions ports, 25% Ethernet. Split of H1 (FF, wireless) and H2 (ethernet) fieldbuses .The convergence of IT and OT technologies, aka the Industrial Internet, represents a multibillion opportunity for IT vendors.Our strategy to promote that convergence includes pushing IPv6 to the industrial M2M endpoints to enable end-to-end connectivity over deterministic wireless networks that are being developed at IEEE to emulate the characteristics of incumbent OT networks This work will benefit IOTG (CIBU)IOTG has already started to incorporate partner solutions (1552S, 1552WU) but in a fragmented market. This project approach will converge and promote an international standard solution (IPv6, 6TiSCH, CoAP, 802.15.4e based). The project leverages standards to drive IPv6 at the endpoints (that we do not own), which in turn justifies the introduction of Cisco equipment in the factory
