6LowApp BOF at IETF 76, Hiroshima by Barry Leiba

6lowapp — Application Protocols for Low-power V6 Networks BOF
The 6lowapp BOF aimed to look at protocol issues for low-power V6 applications, to identify potential work in that area. The organizers have a number of application domains in mind; the two that were particularly presented in the BOF are home and building automation (having, for example, every lamp in the building as a separately addressable/controllable device, in addition to dealing with HVAC, fire control, building security, etc.) and power-system management (smart meters, remote-controllable thermostats, etc.).

Some versions of much of this stuff is working now, in limited environments. The goal here is to generalize the solutions and standardize protocols to be used. The key is the initial scope of the work. The BOF presented two protocol ideas, based on REST (representational state transfer) concepts: one for “Constrained Application Protocol” (CoAP), and one for “Constrained-to-General- Internet Intermediates” (CoGII). Service discovery, device discovery, and system security are key points (and there was discussion of the difference between channel security (where (D)TLS may be used) and object security (where CMS may be used)).

Significant issues/questions:

Questions about how much of this fits into the IETF, and how much is already being done in industry consortia and other SDOs.
Concern about timeline, need for speedy development, normal IETF timeframes. Will the industry be willing to wait for IETF process? Counter: significant momentum behind this, might be able to move through the IETF quickly.
Concern that this be general, not just restricted to constrained environments/devices.
Concern about the CoGII portion, related to location of CoGII intermediary, interaction with REST, and other issues.

Consensus is to work on the CoAP side, but to drop CoGII. The group will move ahead with charter plans.

Smart Cities and Internet of Things

The theory of Internet of Things led to the development of a non-profit organization that is creating a standardized protocol for communication amongst those things. The Internet Protocol for Smart Objects [IPSO] Alliance, funded by companies such as Cisco, Sun Microsystems and Ericsson, aims to promote networking amongst smart objects and deliver information gathered by those objects.

Incheon Metropolitan City in Korea, Cisco is transforming their Free Economic Zone (IFEZ) into a center for globalization expertise, driving "better city management, enhanced quality of life for citizens, and support[ing] sustainable economic development."

Cisco has taken this thinking one step further in their Sustainable Urbanization program. They are developing a holistic, global, intelligent urban initiative to create intelligent cities.

ZDNet: Smart cities, sensors and their potential side effects

An interesting read about possible privacy issues in smart cities

Your future city will be networked to the hilt with sensors that will enable new “urban actors”—think bridges, bricks and traffic signals—that will communicate with its inhabitants. But as cities become more networked there are risks to their evolution.
The argument: Cities have evolved because they provide the opportunity for reinvention and ability to be anonymous. A networked city fabric is a threat. To wit: Do you really want to know everything about your neighbor? If you did know your neighbor’s religion, thoughts and social circle you may know too much. Simply put, sensor-laden cities may become decidedly less comfortable. Greenfield’s talk highlighted how cities evolved with neighborhoods, landmarks and “legibility.” If technologies—think RFID—remove those boundaries it’s hard to model a city.

6LoWPAN WG meeting and 6LowApp BOF covered by ISOC newsletter

ISOC’s Rough Guide to IETF 76’s Hot Topics summerized the 6LoWPAN WG and 6LowApp BOF at IETF 76 as follows:

6lowpan (IPv6 over Low power WPAN)
The 6lowpan WG deals with the use of IPv6 over low powered networks (such as sensornets). This is protocol development for devices on “the Internet of Things”. The basic concept in 6lowpan is that IP may become a unifying layer for low powered devices for interoperability, potentially over the Internet.
6lowpan is intensely focused on developing the protocols to enable this to happen.

Full charter:

Some progress should be made in closing on standardization of a couple of documents (specifically the Neighbor Discovery document).This working group has been going on for some time and has a sense of urgency now due to the SmartGrid efforts currently gaining a lot of attention in the United States.

(10 November, 13:00-15:00)

6lowapp (Application Protocols for Low-power v6 Networks) BOF
6LOWAPP is a BOF considering whether different protocols, or modifications to existing protocols, are needed for very low power devices that may proliferate for sensor type networks. There is a great deal of enthusiasm not just to define the work of a potential working group coming out of this BOF but also to start defining problems and protocols. The mailing list for this BOF has a lot of traffic and the BOF promises to be vigorous.

Self-powered diaper monitor system automatically detects wet diapers

A research laboratory at Japan’s Ritsumeikan University has developed a monitoring system for wet diapers that consists of a self-powered sensor/transmitter and a receiver and is supposed to assist staff in hospitals and nursing homes in performing diaper checks with elderly patients. The sensor kit has to be placed inside the diaper and sends signals to the receiver unit, which was co-developed in collaboration with Seiko Epson.

Both the sensor and the accompanying wireless transmitter are powered by a built-in battery that can generate electricity following a chemical reaction in the presence of urine. Once this happens, the sensor kit can transmit signals to a receiver located as far as 3 meters away.

The university lab says their wet diaper monitoring system is still in prototype mode. One possible area for improvement is to add circuitry to the sensor system so that a single system can monitor a group of people, for example in a nursing home.

ZDNET: 7 things you should know about Body Area Networks (BANs)

The budding field of Body Area Networks gives new meaning to the term “personal” in PCs. In a nutshell, the technology leverages wireless communications protocols that allow for low-powered sensors to communicate with one another and transmit data to a local base station and to remote places like hospitals.

For instance, small flat sensors placed on the skin, or even under it, could be used to create a “medical” body area network that provides doctors with real-time data about their patients’ bio-signs. Another key application is short-range person-to-person communications that could help protect front line soldiers in combat.

The Wi-Fi-zation of things

Big innovations in power consumption and management are making it possible not only to extend battery life for Wi-Fi smartphones, but also to embed Wi-Fi into swarms of new devices and now even wireless sensors: medical monitoring devices, building control systems, real-time location tracking tags and consumer electronics. The result is the ability to continuously monitor and collect data, which can be personalized based on a user's identity and location.

"There's nothing that other contemporary limited-distance RF technologies can do that Wi-Fi can't," writes wireless consultant and Network World blogger Craig Mathias.

"With an enterprise wireless LAN, this infrastructure is already in place," says Atheros' McFarland. "Just add the low-power sensors."

Embedded Wi-Fi vendor Summit Data Communications recently announced 802.11a radios in various plug-in formats to let devices use the uncrowded 5GHz band. Start-up Gainspan offers 11bg Wi-Fi radios, with an IP software stack, that use so little power that wireless sensors can run for years on standard batteries. And Redpine Signals offers a single-stream embedded 11n radio.

802.15.4 Chipset Market to Approach $155 Million in 2014, Says ABI Research

Press Release
Source: ABI Research
On 10:06 am EST, Monday November 9, 2009

LONDON--(BUSINESS WIRE)--Growing interest and investment in and funding for improved building energy management will help fuel demand for products and applications using IEEE 802.15.4 semiconductors.

Over the next five years, 802.15.4 chipset shipments will underpin a host of wireless sensor networks (WSNs) across home, building and industrial building automation, as well as Advanced Meter Infrastructures. This will help fuel the growth of the 802.15.4 chipset WSNs market from just over $10 million in 2008 to nearly $155 million in 2014, a Compound Annual Growth Rate of 87.9% over the period.

To date, the 802.15.4 market has grown steadily, based on proprietary point-to-point solutions and some ZigBee-based AMI infrastructure trials. According to ABI Research principal analyst Jonathan Collins, “With growing interest in the potential for wireless sensor networks in commercial building automation and management systems as well as smaller residential deployments, wireless is set to become a key development in the transition to smart energy management.”


Last ISAExpo, first outing for ISA100 wireless standard

ISA held its last ISAExpo in Houston.

In July this year the International Society of Automation (ISA) Standards & Practices Board (S&P) voted to approve the ISA-100.11a wireless standard Wireless Systems for Industrial Automation: Process Control and Related Applications, thereby making it an official ISA Standard. The approval of this major new industry standard by the ISA S&P Board certified that ISA's accredited procedures had been followed in the development of the standard.

This standard is intended to provide reliable and secure wireless operation for non-critical monitoring, alerting, supervisory control, open loop control, and closed loop control applications. The standard defines the protocol suite, system management, gateway, and security specifications for low-data-rate wireless connectivity with fixed, portable, and moving devices supporting very limited power consumption requirements. The application focus addresses the performance needs of applications such as monitoring and process control where latencies on the order of 100ms can be tolerated, with optional behaviour for shorter latency.

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.

Zigbee Smart Energy Profile

Green Buildings are Gaining Momentum with Wireless Sensor Networking

Initiatives by governments, global alliances, and large public companies such as Cisco, IBM, Johnson Controls, and Siemens are driving innovation and standardization in mesh networking, IP sensing, WiFi Sensors, and energy harvesting. The most impactful technologies for wireless building automation systems today include the following:

ZigBee has the largest market share for building WSN, backed by the top four building automation vendors, end users such as Kroger, and hundreds of manufacturers, systems integrators, and startups. While there are few certified ZigBee products today, the largest current building WSN deployments such as CityCenter consist of ZigBee devices by multiple vendors including Control4, Axxess, Bartech, and SAFLOK. Vendors are currently migrating to the latest ZigBee PRO feature set and the ZigBee Building Automation profile is expected to be published in early 2010.

Energy Harvesting
As much as 15 million wireless sensor nodes will be installed within the next five years that will need to be either battery powered or powered by ambient energy. While operating lifetimes of 10+ years is possible with batteries using the latest radios and protocols, the prospect of disposing of millions of batteries conflicts with WSN's value proposition as a "green" technology. ON World's survey found that battery lifetime continues to be one of the major concerns about wireless sensor networking. Furthermore, the labor costs and setup problems associated with changing batteries gives wireless sensors powered with energy harvesting an unfair advantage.

Demand for greener solutions has driven adoption of battery-less wireless sensors by EnOcean that has spurred the formation of the EnOcean Alliance with 125 members and 350 EnOcean products. The ZigBee Alliance has also launched an energy harvesting initiative to reduce the power consumption of certain devices that will be capable of supporting energy harvesting.

IP Sensor Networking
IT convergence and rapidly developing standards and industry alliances are accelerating the development of IP sensor networking for buildings. Supporting sensor networking across any physical medium, wired or wireless, IP sensor networking encourages innovation by opening up building WSN solutions to a large pool of Internet, IP and IT focused developers. It also brings battery powered 15.4/mesh technologies by Atmel, Dust, and Synapse into the mainstream with increased installation flexibility and robust reliability. Arch Rock has recently achieved the highest IPv6 certification level for its IP sensor networking platform.

WiFi Sensors
The emergence of Low Power WiFi chipsets by GainSpan and others has made WiFi a potentially disruptive technology for building WSN with its intrinsic support for IP. By leveraging the WiFi infrastructure that is installed in tens of millions of buildings, WiFi sensors reduce installation costs, simplify development, and provide easy integration with data networks. ON World's software simulations found that low power WiFi chipsets provide multi-year lifetimes for many building WSN applications, even with dozens of transmissions per hour.

In 2013, the global building WSN market-- including WSN systems, software and services-- will be $4 billion, up from $453 million in 2008.
