1. A bus-based communication system, comprising:
a primary node;
one or more secondary nodes that are each assigned an original node identifier; and
a bus electrically connecting the primary node and the one or more secondary nodes with one another based on a bus-based communication protocol, wherein the bus-based communication protocol defines a predefined number of sequentially numbered available node identifiers, and the original node identifier assigned to each secondary node corresponds to one of the sequentially numbered available node identifiers defined by the bus-based communication protocol of the bus, wherein the primary node implements a re-mapping technique that re-numbers the original node identifiers assigned to the secondary nodes by:
removing unused sequentially numbered available node identifiers;
re-numbering the original node identifiers corresponding to the secondary nodes into sequentially numbered updated node identifiers; and
re-setting a total number of the sequentially numbered available node identifiers equal to a total number of secondary nodes that are part of the bus-based communication system.
