Sink-to-Sink Coordination Framework Using RPL: Routing Protocol for Low Power and Lossy Networks

Table 1

Description of all fields in parent table.

Field	Description
Parent ID	Each node in RPL has the unique 128-bit ipv6 address that becomes each node ID.
DODAG ID	128-bit ipv6 address uniquely identifies a DODAG.
Rank	16-bit rank which determines the parent’s individual position with respect to DODAG root.
DTSN	Destination advertisements trigger sequence number: 8-bit unsigned integer which is set by each node that sends DIO. The purpose of DTSN is to control downward traffic.
Sub-DODAG sink ID	8-bit sub-DODAG sink ID stored at each sensor node.
NOM	Network optimization metric values used for coordination among sink nodes.
