Tutorial 2

Summary form only given. The use of IPv6 on wireless networks allows extending existing IP solutions to small low-cost nodes. A temperature sensor can use a HTTP request to send sensor readings to a central server. A technician can upload new firmware to a node around the world using TFTP as easily as if the node was connected to their computer. This tutorial will provide end-to-end coverage of how IPv6 can be used on low-power constrained wireless nodes. A participant in this tutorial can expect to learn how to understand and implement IPv6 wireless sensor networks. In addition current research directions and new research opportunities will be presented. To begin the tutorial, a brief introduction to IPv6 will be provided for those unfamiliar with this version of the internet protocol. Next the IEEE 802.15.4 networking standard will be presented, which is used by many wireless sensor networks. This will introduce 6L0WPAN, which is the IETF standard used to transmit IPv6 packets across IEEE 802.15.4 networks. With basic IPv6 connectivity coverage of higher-layers will be provided, such as using TCP, UDP, HTTP, and TFTP. This will also touch on work done to define standard higher-layer protocols. Security issues will be covered, especially the required trade-offs to use security in low-power and constrained nodes. Security issues will also include a discussion and demonstration of realistic attacks on wireless sensor networks. A live demonstration will be used throughout the tutorial. This demonstration will help show how these networks can be used in real life, and the simplicity IP gives. The demonstration will attempt to use easily available hardware and software which participants could replicate. Finally current standards and research directions will be presented. As the presenter is an active participant in the various standards being developed for this market, this section should be timely and update with any current developments. and designing the latest sta- dards in this field.
