Design and Implementation of a 6LoWPAN Gateway for Wireless Sensor Networks Integration with the Internet of Things L.F. Schrickte, C. Montez, R. de Oliveira, A.R. Pinto Universidade Federal de Santa Catarina - Brazil Abstract The next big change in the Internet paradigm is called the Internet of Things, in which even the simplest device is connected to the Internet. Wireless tech- nologies are important assets in the diffusion of this concept, as they allow the easy and seamless connection of all devices. Wireless Sensor Networks (WSNs) are being established for sensing and actuating critical applications, like industrial automation, domotics and remote patient monitoring. The 6LoWPAN protocol has been proposed as the key to integrate WSNs and In- ternet Procotols. It is based in the IEEE 802.15.4 standard, which is widely used in low power wireless networks. This paper evaluates the mechanisms of header compression and fragmentation of IPv6 datagrams proposed in the 6LoWPAN standard through experiments using a gateway prototype and IEEE 802.15.4 nodes.
