27 \todo
28 \pages{0-1}
29 short overview, not too long: what do we want, what are we
30 going to do
31
32 basically: how do we talk to our smart home?
33 \paragraph{Human-to-Machine Communication:} especiall in the Internet of Things,
34 Chatty Things need to be accessible for the user and should be easy to talk
35 to.
36 \paragraph{Interoperability} integration into already existing
37 infrastructure.

52 \todo
53 \pages{3}
54 Middleware, Application protocol gateways:
55 \begin{itemize}
56 \item Constrained Application Protocol \cite{draft-ietf-core-coap-18}
57 \begin{itemize}
58 \item machine-to-machine
59 \item everything-built-in
60 \item discovery over multicast, service discovery over /.well-known
61 entry-point
62 \item maps to HTTP => stateless => relies on application gateway
63 \item low protocol overhead and parsing complexity (binary messages)
64 \item only draft status
65 \item UDP with Ack and IDs instead of TCP... (limited state machine)
66 \item proxies
67 \item asynchronous messages
68 \end{itemize}
69 \item MQ Telemetry Transport \cite{mqtt}
70 \begin{itemize}
71 \item TCP/IP
72 \item small overhead: 2 byte header + variable header length
73 \item publish-subscribe with topic names
74 \item binary protocol => application-level gateway
75 \item discovery?
76 \end{itemize}
77 \item Devices Profile for Web Services \cite{zeeb-moritz-ws4d}
78 \begin{itemize}
79 \item TCP/IP -> HTTP -> SOAP -> Web Services. Overhead!
80 \item but very extendable and composable
81 \item discovery as a service
82 \item focused on multiple platforms, deeply embedded and servers
83 \item IPv6 partly experimental
84 \item ROM usage of uDPWS: 45 kByte
85 \end{itemize}
86
87 \end{itemize}
