Nowadays the wireless networks play an important role in our life. Almost all of the mobile phones has Bluetooth and 3G. The mid-end devices has Wi-Fi, too. Our mobile phone is becoming an information source and a universal remote control. The topic of my thesis is about 6LoWPAN. It is communication solution over IPv6 for low-power devices. This was standardized by the IETF. The technology is not widely prevalent, but likely it will outlive the similar protocol stack. It is based on IP in this manner it fits easily to the extant networks like the internet.

Building of a test network was my task. The elect software library was not capable to build such a network. The edge router was the bottleneck of the system. It is responsible to connect the 6LoWPAN network to the existing network fabric. I have analysed many solution that could be usable to build a working network. Most of the possibilities failed because the documentation has mistakes or it was not clear enough. This is how it works in the world of the opensource software solutions. Finally at the end of my task I have found a good solution: the TinyOS embedded operating system and the BLIP. I ported the system to the hardware platform that I have used.

The thesis gives a good and well-formed outline about the topic. It deals with the usable hardware and software components with its opportunities and pitfalls. If you are interested in that topic this thesis is the perfect choice to start with. You can save a lot of time.
