Executive Summary

In this paper, the authors show that Web protocols and technologies are good candidates to design the Internet of Things. This approach allows anyone to access embedded devices through a Web application, via a standard Web browser. This web of things requires to embed Web servers in hardware-constrained devices. They first analyze the traffics embedded Web servers have to handle. Starting from this analysis, they propose a new way to design embedded Web servers, using a dedicated TCP/IP stack and numerous cross-layer off-line pre-calculation (where information are shared between IP, TCP, HTTP and the Web application). They finally present a prototype - named Smews - as a proof of concept of their proposals.
