8 Service requirements of SCN applications
The followings are high-level service requirements of SCN applications.

8.1 Connectivity
1) SCN applications are required to support three types of communications:
– SCN controller-actuator communication: actuators communicate with the SCN
controllers;
– Infrastructure communication (including one-to-one, one-to-many, many-to-one and
many-to-many): motes from different mote groups communicate with each other and
with the SCN controllers;
– SCN controller-NGN communication: NGN elements communicate with the SCN
controllers.
2) SCN applications are recommended to support the following type of communications:
– Mote-actuator communication (including one-to-one, one-to-many and optionally
many-to-one and many-to-many): actuators communicate with motes.
3) SCN applications can optionally provide these types of communications:
– Inter-actuator communication: actuators communicate with each other;
– Actuator-NGN communication: NGN elements communicate with actuators;

– Mote-NGN communication: NGN elements communicate with motes.

8.2 Mobility support
Actuators as well as motes can be classified as follows:
– Network-specific actuators and motes, designed to operate in specific SCN application
fields (e.g., complex industrial mechanisms);
