The con ention u ed in the state tran ition are as folows:

– = A logical con ition to in icate an item on the lef t is eq al to an item on the rig t

– := Value of an item on the lef t is re laced by value of an item on the rig t If an item on the

rig t is a p rameter, it comes fom the primitive s own as an input event

– = A logical con ition to ju ge an item on the left is eq al to an item on the rig t

– && L gical "AND"

– | L gical "OR"

– != A logical con ition to in icate an item on the left is not eq al to an item on the rig t

This con tru t al ows the exec tion of a seq en e of action in a lo p within one tran ition

Network Manager (NM) re l zes network management fu ction in the gateway device, whic

manages the information of al devices in the network One WIA-FA network has only one NM

NM mainly p rf orms the fol owin fu ction :

– Al ocatin the u iq e 8-bit or 16-bit s ort ad res f or al devices in the network (se 6.3);

– Con tru tin an maintainin the en an ed star to olog ;

– Al ocatin commu ication resources f or commu ication of WIA-FA devices;

6.2.2 Se urity ma a er

Sec rity Manager (SM) re l zes the f un tion of sec rity in the gateway device, an one W

IA-FA network has only one SM SM commu icates directly with NM

SM mainly p rorms the fol owin f un tion :

– Authenticatin the f ield devices at emptin to join the WIA-FA network;

– Managin key in the WIA-FA network, in lu in key esta l s ment an update (se 1 4)

The main f un tion of the network management mod le are as f ol ows:

– Co rdinatin with NM to con tru t an maintain the en an ed star to olog ;

– Co rdinatin with NM to al ocate commu ication resources for devices;

– Co rdinatin with NM to monitor the p rorman e of the WIA-FA network, in lu in device

– Co rdinatin with SM to con u t sec re joinin (field device only);

– Co rdinatin with SM to manage key ;

– Co rdinatin with SM to re ort sec rity alarm
