"Urban WSNs Routing Requirements in Low Power and Lossy Networks", Mischa Dohler, Thomas Watteyne, Tim Winter, Dominique Barthel, Christian Jacquenet, Giyyarpuram Madhusudan, Gabriel Chegaray, 21-Oct-08. ( bytes)

The application-specific routing requirements for Urban Low Power and Lossy Networks (U-LLNs) are presented in this document. In the near future, sensing and actuating nodes will be placed outdoors in urban environments so as to improve the people's living conditions as well as to monitor compliance with increasingly strict environmental laws. These field nodes are expected to measure and report a wide gamut of data, such as required in smart metering, waste disposal, meteorological, pollution and allergy reporting applications. The majority of these nodes is expected to communicate wirelessly which - given the limited radio range and the large number of nodes - requires the use of suitable routing protocols. The design of such protocols will be mainly impacted by the limited resources of the nodes (memory, processing power, battery, etc.) and the particularities of the outdoor urban application scenarios. As such, for a wireless Routing Over Low power and Lossy networks (ROLL) solution to be useful, the protocol(s) ought to be energy-efficient, scalable, and autonomous. This documents aims to specify a set of requirements reflecting these and further U-LLNs tailored characteristics.

"Industrial Routing Requirements in Low Power and Lossy Networks", Dust Networks, Pascal Thubert, Sicco Dwars, Tom Phinney, 30-Oct-08. ( bytes)

Wireless, low power field devices enable industrial users to significantly increase the amount of information collected and the number of control points that can be remotely managed. The deployment of these wireless devices will significantly improve the productivity and safety of the plants while increasing the efficiency of the plant workers by extending the information set available from wired systems. In an industrial environment, low power, high reliability, and easy installation and maintenance are mandatory qualities for wireless devices. The aim of this document is to analyze the requirements for the routing protocol used for Low power and Lossy Networks (LLN) in industrial environments.

"Home Automation Routing Requirements in Low Power and Lossy Networks", Giorgio Porcu, 19-Nov-08. ( bytes)

This document presents home control and automation application specific requirements for Routing Over Low power and Lossy networks (ROLL). In a modern home, a high number of wireless devices are used for a wide set of purposes. Examples include actuators (relay, light dimmer, heating valve), sensors (wall switch, water leak, blood pressure) and advanced controllers. Because such devices only cover a limited radio range, routing is often required. The aim of this document is to specify the routing requirements for networks comprising such constrained devices in a home control and automation environment.

"Overview of Existing Routing Protocols for Low Power and Lossy Networks", Arsalan Tavakoli, Stephen Dawson-Haggerty, P Levis, 17-Oct-08. ( bytes)

Networks of low power wireless devices introduce novel IP routing issues. Low-power wireless devices, such as sensors, actuators and smart objects, have difficult constraints: very limited memory, little processing power, and long sleep periods. As most of these devices are battery-powered, energy efficiency is critically important. Wireless link qualities can vary significantly over time, requiring protocols to make agile decisions yet minimize topology change energy costs. Routing over such low power and lossy networks has novel requirements that existing protocols may not address. This document provides a brief survey of the strengths and weaknesses of existing protocols with respect to this class of networks. From this survey it examines whether existing protocols as described in RFCs and mature drafts could be used without modification in these networks, or whether further work is necessary.

"Terminology in Low power And Lossy Networks", JP Vasseur, 27-Oct-08. ( bytes)

The documents defines a terminology for discussing routing requirements and solutions for networks referred to as Low power and Lossy Networks (LLN). A LLN is typically composed of many embedded devices with limited power, memory, and processing resources interconnected by a variety of links. There is a wide scope of application areas for LLNs, including industrial monitoring, building automation (e.g. Heating, Ventilating, Air Conditioning, lighting, access control, fire), connected home, healthcare, environmental monitoring, urban sensor networks, energy management, assets tracking, refrigeration.

"Building Automation Routing Requirements in Low Power and Lossy Networks", Jerry Martocci, Nicolas Riou, Pieter Mil, Wouter Vermeylen, 29-Oct-08. ( bytes)

The Routing Over Low power and Lossy network (ROLL) Working Group has been chartered to work on routing solutions for Low Power and Lossy networks (LLN) in various markets: Industrial, Commercial (Building), Home and Urban. Pursuant to this effort, this document defines the routing requirements for building automation.
