A Two-Level Communication Routing Algorithm Based on Vehicle Attribute Information for Vehicular Ad Hoc Network

Algorithm 4

How destination nodes send RREP.

Operation Flow

1:  Input: cluster information

2:  If the is the source of the RREQ it received

3:    if the and the node are in the same cluster

4:        node sends RREP

5:        free this RREQ

6:    else

7:        free this RREQ

8:  else

9:    if the destination node is the and the is the

10:     node index sends RREP

11:     free this RREQ

12:      else

13:     if is the

14:       node sends RREP

15:       free this RREQ

16:    End
