all limitations of processing power are mitigated. However,
more data must be sent and received by the sensor- and
actuator nodes since much of the control logic has been
moved out of the local mobile cloud. Integration of Internet
services and sensor node is currently an important research
field, see for example [22].
Since a user might want to be able to configure his or
her network in an optimal way, a combination of the three
levels might be desirable. By dynamically utilize services
at different levels, an optimum on performance and power
consumption can be achieved. For example, several sensors
can cooperate using level 1 in order to detect an anomaly.
When a deviation from the normal is detected, one or several
services can be utilized on the gateway level, thereby allow
services with relatively high memory and processing power
to be utilized. Finally, when alarms are to be generated, or
other systems and services could be invoked, the third level
could be used to offload node and gateway devices.
