IETF 6LowApp BOF at Hiroshima

The 6LowApp BOF will be held in Hiroshima with the goal to form a new Application area working group at IETF.

The 6LowApp activity of the IETF coordinates work in the IETF to specify application (as well as possibly transport, security and operations) protocols for constrained nodes and networks, the Wireless Embedded Internet.

6LowApp is not itself yet an IETF Working Group, but is intended to result in the creation of IETF Working Groups. In the 6LowApp activity, definition of work will be carried out as well as initial work leading up to specifications.

6LowApp was kicked off in the BarBofs/IETF75/6LowApp "Bar BOF" at IETF 75 in Stockholm. During this successful BarBof?, five areas of interest were identified: Application Protocols, Service Discovery, Transport, Security and Data Representation.

The drafts that may be discussed are as follows:

6LoWPAN open source stacks

1- Contiki
Contiki is an open source, highly portable, multi-tasking operating system for memory-efficient networked embedded systems and wireless sensor networks. Contiki has been used is a variety of projects, such as road tunnel fire monitoring, intrusion detection, water monitoring in the Baltic Sea, and in surveillance networks. Contiki provides IP communication, both for IPv4 and IPv6. Contiki and its uIPv6 stack are IPv6 Ready Phase 1 certified and therefor has the right to use the IPv6 Ready silver logo.
Contiki is written in the C programming language and is freely available as open source under a BSD-style license.

2- Berkeley IP

Its an implementation of IPv6 for TinyOS. It uses 6lowpan/HC-01 header compression, and includes IPv6 neighbor discovery, default route selection, point-to-point routing, and network programming support. It has been tested on micaz, telosb, and epic platforms. Standard tools like ping6, tracert6, and nc6 can be used to interact with and troubleshoot a network of blip devices, and pc-side code is written using the standard BSD sockets API (or any other kernel-provided networking interface). A sensor network can also be easily mapped into the public subnet to provide global connectivity.

Book Published: RFID and Sensor Networks: Architectures, Protocols, Security and Integrations

Integrating Radio Frequency Identification (RFID) and Wireless Sensor Networks (WSN) for the first time, this comprehensive text explains the importance of their complementary nature, flexible combination, and ubiquitous computing. With a section devoted to each individual element, the text covers the tags, readers, and middleware associated with RFID. It then provides insight into the routing, medium access control, and cross-layer optimization of WSN. The book discusses the enhanced visibility and monitoring capability that is possible and observes practical uses such as a smart home, a surveillance system, and applications for personal health care.

TI: 6LoWPAN Introduction by Geoff Mulligan (Sept 2008)

Low Power RF Developer - Special Guest, Geoff Mulligan

In this video, Geoff Mulligan of Mulligan Labs, discusses 6LowPAN. What is 6LowPAN? It's a way to make IP and 802.15.4 work, it's an internet standard (RFC4944), it has a small footprint (code and ram) and it's available today for TI products. For more information watch Geoff's video and visit 6LowPAN.org.
