1. A few words on the Terminology: when we first started this initiative the name of RSN (Routing for Sensor Networks) was chosen thus the name of the current mailing list. Because this work applies to a variety of constrained devices (sensors but also actuators, switches, …), the more generic term of L2Ns is now used when referring to networks made of such devices. So we moved to RL2N (Routing for L2Ns). Should a WG be formed there is a consensus to name it ROLL: Routing Over Low power and Lossy networks.

2. Brief Introduction

Low Power and lossy networks (L2Ns) (e.g. Sensor Networks) have very specific routing requirements. A plethora of proprietary routing protocols have been developed by various companies or ad-hoc SDOs during the past few years. Considering that L2Ns do require an end-to-end IP solution to extend the Internet to the Internet of Things, an IP-based routing solution for such networks is highly required.

Brief description: Welcome to this non-WG mailing list (created April 2007). The aim of this list is to have some discussion at the IETF on Routing issues for Sensor Networks. Indeed, a plethora of proprietary protocols have emerged during the past few years for Sensor Networks and the objective is to find a consensus on an IP based routing architecture and protocol(s) for Sensor Networks. The outcome of the discussion might be to organize a BOF (not approved at the time of the creation of this mailing list) or to end up with the formation of a new WG with an exclusive focus on the routing issues that would work in concert with other WGs dealing with Sensor Networks (e.g. 6lowpan). First we would like to have an detailed discussion on the routing requirements so as to study whether existing routing protocols could be used (e.g. AODV, OLSR, ...) or adapted; alternatively we may need to design a new routing protocol if none of the existing routing protocols satisfy the highly constrained requirements of Sensor Networks.
