A communication(s) channel (also called a circuit or line) is

Overview Edit

Basic properties, assumptions, recommendations, and general statements about communication channel include:

1. Communication channels move data between computing, sensing, and actuation.
2. Since data is the "blood" of a NoT, communication channels are the "veins" and "arteries", as data moves to and from intermediate events at different snapshots in time. . . .
3. Communication channels will have a physical or virtual aspect to them, or both. Protocols and associated implementations provide a virtual dimension. Wires provide a physical dimension.
4. Communication channel dataflow may be unidirectional or bi-directional. There are a number of conditions where an aggregator might query more advanced sensors, or potentially recalibrate them in some way (e.g., request more observations per time interval).
5. No standardized communication channel protocol is assumed; a specific NoT may have multiple communication protocols between different entities.
6. Communication channels may be wireless.
7. Communication channels may be an offering (service or product) from third-party vendors.
8. Communication channel trustworthiness may make sensors appear to be failing when actually the communication channel is failing.
9. Communication channels can experience disturbances, delays, and interruptions.
10. Redundancy can improve communication channel reliability. There may be more than one distinct communication channel between a computing primitive and a sensing primitive.
11. Performance and availability of communication channels will greatly impact any NoT that has time-to-decision requirements. . . .
12. Security and reliability are concerns for communication channels.
