Forwarding a packet in a sensor personal area network

Method to forward a packet (P) according to predefined protocol steps in a sensor personal area network (PAN1) comprising data communication sensor devices (SN1, SN2, SN3, SN4, SN5, . . . ), said method comprises by an originating node (SN3):

• inserting with a first inserter (INS1) a predefined compression value (cv) in a compression field (C-F) in said packet (P) and indicating thereby that a source network identifier of said originating node (SN3) being assumed equal to a destination network identifier of an intended recipient of said packet (P);
• and
• inserting with a second inserter (INS2) a predefined label switching value (Isv) in an addressing mode field (DAM-F) in said packet (P) and thereby indicating that said protocol steps comprises a label switching principle that must be applied to forward said packet (P);
• and
• inserting with a third inserter (INS3) a label value (lab1) in a source network identifier field (SNI-F) in said packet;
• and
• by an intermediate node (SN1):
• interpreting with a first interpreter (INT1) said predefined compression value (cv) in said compression field (C-F) and thereby determining that said source network identifier of said originating node (SN3) of said packet being assumed equal to a destination network identifier of an intended recipient of said packet;
• and
• interpreting with a second interpreter (INT2) said predefined label switching value (Isv) in said addressing mode field (DAM-F) and thereby determining that said protocol steps comprises a label switching principle that must be applied for forwarding said packet (P), and accordingly thereby triggering a retriever (RET);
• and
• retrieving with said retriever (RET) said label value (lab1) from said source network identifier field (SNI-F), said label value (lab1) being used by said intermediate node (SN1) for forwarding said packet according to said label switching principle.

A Sensor node (SN1) to forward a packet (P) according to predefined protocol steps in a sensor personal area network (PAN1) comprising data communication sensor devices (SN1, SN2, SN3, SN4, SN5, . . . ), said sensor node comprises

• a first interpreter (INT1) to interprets a predefined compression value (cv) in a compression field (C-F) in said packet (P) and to thereby determine that a source network identifier of an originator (SN3) of said packet being assumed equal to a destination network identifier of an intended recipient of said packet,
• characterized in that said sensor node (SN1) further comprises
• a second interpreter (INT2) to interprets a predefined label switching value (Isv) in an addressing mode field (DAM-F) in said packet (P) and to determine thereby that said protocol steps comprises a label switching principle that must be applied to forward said packet (P), and accordingly to trigger thereby a retriever (RET);
• and
• said retriever (RET) to retrieve a label value (lab1) from a source network identifier field (SNI-F) in said packet, said label value (lab1) being used by said sensor node (SN1) to forward said packet according to said label switching principle.
