White Paper #1 4.2.2008, Public IP-based Wireless Embedded and Sensor Networks: The WiFi of the Embedded World Zach Shelby Introduction This white paper gives an introduction of Sensinode IP-based wireless embedded and sensor network technology. The basics behind the technology and how it is quickly becoming the next WiFi success story are introduced, along with the applications of the technology. The next WiFi The use of wireless technology in a huge range of embedded applications from building automation to environmental monitoring and industrial automation has become a huge trend over the last years. Until the release of the IEEE 802.15.4 short-range low-power wireless standard, the industry was paralyzed and fragmented by proprietary radio products. ZigBee soon followed with a vertical approach for specific application profiles over 802.15.4. ZigBee however has left much of the industry alienated with a lack of profiles, long learning curves, difficult certification and incompatibility with IP-based enterprise systems, together with scalability problems. To this day the majority of 802.15.4 chips shipped are running with completely proprietary protocols. In 2007 the IETF released a new standard for using IPv6 over 802.15.4 called 6LoWPAN, opening the door for the Internet into all embedded wireless devices. At Sensinode we believe this combination of 802.15.4 and IPv6 will be an explosive success, becoming the WiFi of the embedded world. In this white paper we look at how this technology can be applied in enterprise systems. Applications IP-based 802.15.4 networks have their greatest potential in large-scale deployments with mobility, and the need for integration with back-end IP-based systems such as SAP business systems, Web- services or SCADA. Some key example enterprise applications include: Building automation Facility management Automatic meter reading Environmental monitoring Industrial automation Asset management Logistics The market for 802.15.4 is growing at incredible speed, replacing most proprietary technologies on the market and opening up entire new applications. According to On World growth is over 200% annually with the 100 million-unit mark being broken in 2009. On World’s industrial WSN reports White Paper #1 4.2.2008, Public also indicate that IP-based technologies will also dominate that market segment by 2009 with over 55% of the market supporting ISA100 (6LoWPAN based) in addition to a huge amount of plain 6LoWPAN usage. Benefits It is easy to see the advantages of applying IP in all embedded networks, especially since 6lowpan technology allows IPv6 with low overhead and power consumption in the smallest of devices. The benefits of using IP-based 802.15.4 from Sensinode include: Open standard, with long lifetime (10s of years) Easy learning curve, everyone knows the Internet Transparent Internet integration Network maintainability and scalability ”You never lose with IP” Technology & architecture The technology used in these networks is very easy to understand, as the same terminology and tactics used in the Internet are applicable. 6LoWPAN networks are either extensions of the Internet through access points or ad hoc islands. Sensinode router products are called NanoRouters™. The network is made up of any wireless device implementing the 6LoWPAN and 802.15.4 standard. Sensinode wireless nodes are called NanoSensors™. Typically networks are semi- infrastructure based, with wireless nodes either speaking directly to NanoRouters™, or multi-hop through other peers. In 6LoWPAN networks mobility between routers is very common. Sensinode networks make use of scalable Internet tools such as ICMP to build and maintain networks. Sensinode NanoMesh™ routing provides a simple ”few more hop” solution for routing in enterprise 6LoWPAN networks. Applications for 6LoWPAN networks are made in a very similar way to the Internet. Sensinode NanoStack™ provides a standard Socket API for accessing the network. Applications are built upon UDP and communicate between 6LoWPAN nodes, or with the core network. Compressed 6LoWPAN frames are uncompressed in NanoRouters™ for full UDP/IPv6 compatibility in the Internet.
