Messages

Generic

Message = {Source, Destination, Type, Data}

success

Type = success
Data = {Request}

failure

Type = failure
Data = {Request, Error}

Discovery

beacon

Type = beacon
Data =
        {[Class,
                [Object, ...]]}

Data

sensor-data-query

Type = sensor-data-query
Data =
        {Request,
        [Object, ...]}

sensor-data

Type = sensor-data
Data =
        {Request,
        [{Timestamp, Validity,
                [{Object, Data},
                ...]},
        ...]}

sensor-data-monitor-create

Type = sensor-data-monitor-create
Data =
        {Monitor,
        [Object, ...]}

• we could also add threshold, update count, validity;

sensor-data-monitor-destroy

Type = sensor-data-monitor-destroy
Data = {Monitor}

Management

reset

Type = reset
Data = {Request}

Miscellaneous

uuid-request

Type = uuid-request
Data = {}

uuid-response

Type = uuid-response
Data = {Uuid}
