Your remark about WSN and TCP is interesting. In fact, it has been shown that TCP fits badly with WSN (with multi-hop routing), mainly because of the irregularity of latency and losses in such network. Providing a real TCP support makes sense in a sensor or any other device, but it is probably not a good deal to use it for communications inside a wireless sensor network.

That sounds really sweet what you're working on, I'd love to know more about it (would love to read the ICESS paper you mention :) Well, we don't really use gateways "because" of the lack of tcp/ip, but because it's simple and ready to integrate existing WSN deployments (for example) with the Web while minimizing the Web. I think the point is ideally a world filled with web-enabled devices (ideally directly with tcp/ip). Just that some old schoolers will disagree with that, saying that tcp/ip, or worse http, shouldn't be used for embedded devices, as it's way too slow. I don't agree necessarily, and what I found interesting is to compare and see what is actually the price to pay for using web on devices. Keep up the good work and don't hesitate to send us the paper when it's out! Hi Simon, thanks for the notes!

This blog will probably help the Web of Things to become well-known and more popular. I fully agree with this vision of a Web of Things, which is to the Internet of Things what the Web is to the Internet. As a PhD student of the university of Lille, France, I am working on topics related to yours. I focus on the system aspects of the embeddability of autonomous Web servers (with no underlaying OS, and with its own TCP/IP stack). One of my aims is to prove that Web servers can be embedded in extremely constrained (and cheap) devices, starting from 200 bytes of RAM, 8 kilo-bytes of EEPROM and a 8 bit CPU cadenced at a few MHz. In your papers about the Web of Things, you make use of a gateway because of the lack of TCP/IP support in your devices. So I think it is interesting to tell you that my prototype is open-source. It is publicly available, and can be ported to any target, with or without an OS. You will find more information about it on this page : http://www2.lifl.fr/~duquenno/Research/Smews I have one conference paper about it (at ICESS'O9, which is airing now). It is called "The Web of Things: interconnecting devices with high usability and performance", and will be available in a few days. A good news is that the term "Web of Things" seams to be well appropriated, since we have chosen it simultaneously :) Simon Hi Dominique and Vlad,
