After Sauna and Jacuzzi, 6LoWPAN

We all went to the get-together party evening. It was so excitement when I got first experience of Sauna and Jacuzzi. After the many Finnish beers, I was completely down.

I attened IP based wireless sensor network (WSN) workshop. Tutor is an author of 6LoWPAN book. Zach views the WSN from the networking point of view - connecting the WSN with Internet or fitting into the TCP/IP stack. 6LowPAN reduces IPv6 header from 48 bytes to 2 bytes.

More interesting point for me is that there is a need to go for the new apppliction protocol for the WSN. This new protocol is a kind of optimization of HTTP (reduce overhead) and has new features such as eventing/push support natively. Zach et al propose a new protocol called Constrained Application Protocol - CoAP.

It is in the line of changing the user model of the web that consits of HTTP, URI and HTML. This concept is written in the paper "The smart internet: transforming the web for the user".
