6LoWPAN Troubleshooting with Foren6

foren6-400p-alphaForen6 is an effort to provide a non-intrusive 6LoWPAN network analysis tool. It leverages passive sniffer devices to reconstruct a visual and textual representation of network information to support real-world Internet of Things applications where other means of debug (cabled or network-based monitoring) are too costly or impractical.

  • Visualize your 6LoWPAN network. Foren6 uses sniffers to capture 6LoWPAN traffic and renders the network state it in a graphical user interface.
  • Detect routing problems. The Routing Protocol for 6LoWPAN Networks, RPL, is an emerging IETF standard. Foren6 captures all RPL-related information and identifies abnormal behaviors.
  • On-site diagnosis. Foren6 captures live packets from deployed networks in a non-intrusive manner. Multiple sniffers can be combined for extended coverage.
  • Debug-oriented. Rewind the packet capture history, replay a previous packet trace and navigate through different overlays to pinpoint problems.
  • Customize to your infrastructure. The network viewer uses floating positions, or user-defined layouts to visualize sensors in their real setting.
  • Android support. An Android port is under development, allowing to visualize 6LoWPAN networks on a tablet. It is ideal for walking around in a WSN.

IBM and Libelium Launch Internet of Things Starter Kit

IBM and Libelium, a wireless sensor network hardware provider, today released an Internet of Things Starter Kit to enable dozens of sensor applications ranging from monitoring parking spaces or air pollution to providing assistance for the elderly.

Created by IBM scientists and Libelium engineers to ease application development, testing, and scalability of wireless sensor networks (WSN), the new Internet of Things Starter Kit integrates Libelium’s Waspmote wireless sensor platform with IBM’s Mote Runner software and 6LoWPAN, which allows every single sensor and device to connect directly to the Internet using the new IPv6 protocol.

IBM Mote Runner is an open software development platform that connects sensor and actuator motes within wireless sensor networks based on the IETF 6LoWPAN protocol specification. With the new Internet of Things Starter Kit, a real-time operating system is integrated in Libelium Waspmote nodes to support more that 60 different sensors available “off the shelf,” allowing developers to easily build any application on top. The Internet of Things SDK also includes the source code of the 6LoWPAN libraries so that researchers can modify and add their own algorithms and improvements.

“We have worked closely with IBM to offer a development platform that can be used for both simulation and real IPv6 sensor connectivity,” said David Gascón, CTO at Libelium. “This platform is a powerful tool for improving and testing 6LoWPAN capabilities in the context of wireless sensor networks and the Internet of Things.”

“If we can harvest the Big Data insights from all of the things connected to the Internet we can more precisely understand how our world actually works,” said Thorsten Kramp, a computer scientist at IBM Research. “By making Internet of Things application development easier, the answers to the grand challenges of our age becomes more feasible.”

The Waspmote Mote Runner Developer Kit is available today at here.

World’s First Online Development Environment for the Internet of Things Announced

Thingsquare  announced Thingsquare Code, to help connect products such as light bulbs, thermostats, and smart city systems to smartphone apps. Thingsquare Code is the world’s first online interactive development environment (IDE) for the Internet of Things and works with a number of recent chips that target the emerging Internet of Things market, from leading chip vendors Texas Instruments and ST Microelectronics.

Thingsquare Code lets developers of Internet of Things products program their wireless chips from a web browser. Before Thingsquare Code, developing Internet of Things products used to be time-consuming and would require extensive expertise on behalf of the developer. With Thingsquare Code, developers can quickly prototype and validate their products, directly from their web browsers.

“The latest IP/6LoWPAN solutions for IoT applications from Texas Instruments (TI) will be ready for Thingsquare Code,” said Oyvind Birkenes, general manager, Wireless Connectivity Solutions, TI. “Thingsquare opens the door to developers from various disciplines to connect their products faster to the Internet. This is truly revolutionary.”

“Thingsquare Code already works with a number of microprocessor platforms, including the ARM Cortex M3 and the TI MSP430,” said Thingsquare chief architect Adam Dunkels. “With our secure cloud connectivity solution, devices can be programmed without cables and without having to install compiler toolchains, which is a large step forward for IoT programming.”

Thingsquare Code is currently available for beta testers and will be available for use with a number of wireless chips for the emerging Internet of Things market developed by Texas Instruments and ST Microelectronics.

Why the Internet of Things Needs IPv6

The transition to IPv6 is important not only because the 4.3 billion IPv4 addresses are running out, but also because the proliferation of Internet-connected devices is creating a new environment of information. “The Internet of Things is very much upon on us,” said Vint Cerf, Google’s chief Internet evangelist, at the Rocky Mountain IPv6 Summit on Thursday, April 18, in Denver.

Every device that connects to the Internet requires an IP address, and it has been predicted that by 2020 there will be 50 billion Internet-enabled devices in the world. To put that number in perspective, that equates to more than six connected devices per person, based on an expected global population of 7.6 billion people. “With the explosion of mobile devices — especially as asset intelligence and machine-to-machine embed connectivity in literally everything — unique IP addresses are becoming a scarce resource,” according to Deloitte.

Thus the move to IPv6 is necessary as it provides an almost unimaginable number of IP addresses — 18 quintillion blocks of 18 quintillion possible addresses.

In a prerecorded video speech, Cerf said the proliferation of Internet connections will include automobiles. While not as high-tech as Google’s self-driving car, Cerf said in the future, vehicles will report their condition and other information in order to aid maintenance. In addition, medical and scientific instruments will automatically record and report their status as well as the data they collect. “So all of you working on IPv6 are in fact working on a much larger and much more challenging scope and that is this avalanche of content and information,” Cerf said.

In addition to allowing for an increasingly connected world, IPv6 will also benefit public safety communications. Latif Ladid, president of the Global IPv6 Forum, said IPv6-enabled devices, such as iPhones, provide better communication interoperability than first responders currently have. Upgrading to the new protocol will allow public safety workers to use LTE directly, enabling the sharing of not only voice communications, but also photos and videos. However, proprietary solutions and legacy systems can halt progress. “We have found that this is an important area that is going to take more decision-making than just the technology itself,” Ladid said.
