Wireless Sensing Solutions '05 Summary

The Wireless Sensing Solutions Conference 2005 wrapped up yesterday in Chicago. All in all, I think it was a pretty good show. There were roughly 350 attendees, about 17 exhibitors, and 80 or so presenters. From what I heard, the turnout was slightly better in 2004, but there was a lot to see and learn this week none the less.

The presentations were pretty good for the most part. They were originally supposed to consist of simultaneous discussions in one of three separate tracks - Technology Solutions, Systems Integration, and Case Studies. A last minute addition was a Venture Capital track that catered to the non-technical folk at the show. There was a lot to learn in all the tracks, and the only way to get the most of the show was to go with 3 or 4 people and share the knowledge from each track. In my opinion, the tracks weren't really that focused on their original topics and it was the luck of the draw as to which track was the most informative. General consensus was the VC Forum was pretty much a waste of time because they hardly discussed Wireless Sensors at all.

The exhibitors were mostly your well known hardware companies trying to push their products (without having an actual solution). There were one or two companies that actually had solutions to real-world problems. My hope is that next year we will see many more end-user products and solutions that utilize wireless senor technology.

The show concluded with a rather sparse turnout to a Panel Discussion on the future of wireless sensor networks. Although the attendance was light, the discussion was a good one. It was a mix of business and technology experts, with the former arguing that enough innovation has occurred and its time to start finding the business model. The technologists argued that there is still a good deal of innovation that needs to occur before the technology is adopted by industry. Personally, I think they are both right. This technology will continue to evolve, but solutions to real world problems can be developed now using this technology. It will be interesting to see how things have changed by the time next year's Wireless Sensing Solution rolls around.

Octave Technology Announces Release of OCTAVEX Beta

Octave Technology announced yesterday that the OCTAVEX Wireless Sensor Network middleware framework is now available for download from Octave Technology (http://www.octavetech.com/solutions/octavex.html). They are providing a BETA version of the product free of charge for testing and evaluation purposes, and welcome all feedback and questions.

The OCTAVEX Framework is a Web Services based Wireless Sensor Network middleware framework built using the Microsoft .NET platform. The goal of OCTAVEX is to create a scalable, reliable, easy to deploy and maintain platform for delivering wireless sensor data in a simple XML format. OCTAVEX is the bridge between low level sensor networks and advanced enterprise applications.

Some features of OCTAVEX include:
  • enterprise quality software utilizing web-services architecture for scalability and ease of integration
  • custom gateways that interfaces directly with the sensor network to calculate engineering values and publish data in a simple XML format. Current support for TinyOS based networks. Support for additional hardware available soon.
  • built using the .NET platform, eliminating the need for UNIX emulators or complicated J2EE application server software
  • a web-based GUI that utilizes AJAX technology, as used by Google Maps, to display real-time sensor and alert data, as it occurs.
  • built-in business logic such as custom views, rule processing, alert delivery, data archiving, and historical data graphing
  • automated installation and deployment scripts - all processes run as windows services or IIS web applications
OCTAVEX runs on any Windows based machine that supports the IIS Web Server, including Windows 2000, XP Pro, and Windows Server 2003. For a full description of the system requirements and installation steps, please refer to the OCTAVEX Getting Start Guide located at http://www.octavetech.com/octavex/documentation.html.

The evaluation version of the OCTAVEX Framework can be downloaded by going to http://www.octavetech.com/solutions/octavex.html. Questions or feedback can be sent to octavex@octavetech.com.

Downsizing is the future of the eGrain

Here is a great article that talks about a German company, eGrain (here is the link to their website for those that can read German) that is making great progress in shrinking wireless sensor network hardware down to true "smart dust". The current size of their network nodes are about 1 cubic centimeter, about the size of a sugar cube. They are confident that they will be able to reach the size of a match head in a few years, once the right type of thin polymer batteries are available.

The article gives a great introduction into the potential this technology has for the future. It concludes with a description of a remarkable application that places their hardware inside a golf ball to improve a golfer's game by measuring how fast the ball flies off the tee.

One Million Wireless Sensor Network Nodes to be Deployed in 2005

According to a recent report by ON World the number of wireless sensor network nodes deployed in 2005 will reach over 1 Million - triple of what was deployed in 2004. The link below also provides some interesting statistics about the recent report which is entitiled "Wireless Sensor Networks: Growing Markets, Accelerating Demand". It states that dozens of sensor networks with over 500 nodes have been successfully deployed as well as several that are over 1000 nodes. There have also been numerous successful WSN deployments in harsh industrial settings.

Tiny Sensors Run Forever (Almost)

Here is a great article from Wired Magazine about some upcoming Zigbee products that will be unveiled at the Zigbee Open House later this month. Most of the early products are focused on home security, but experts are predicting that the technology will be deployed more broadly in the near future.

The article discusses two products that will be introduced - Home Heartbeat to monitor things like water pipes, electrical devices, and garage doors in your home; and a product by Lusora, to monitor elderly people in their homes.

The article continues with an excellent description of the benefits of Zigbee over other wireless standards. The low data rate which allows for longer battery life, as well as the ease of connectivity is discussed.

Jennic pushes Zigbee compliant microcontroller

For the hardware people out there, here is some information about the new single-chip Zigbee compliant microcontroller that Jennic recently started producing. The device, labeled JN5121, combines a 32-bit RISC core, 2.4GHz IEEE802.15.4 transceiver and integrated 64KB ROM and 96KB RAM memory blocks, all in a single 8x8mm 56 lead QFN chip package.
