Adaptive Beaconing in Mobility Aware Clustering Based MAC Protocol for Safety Message Dissemination in VANET

Algorithm 2

Priority assignment mechanism for safety messages.

Step  1: vehicle x broadcasts message

Step  2: another message is received at the same

       channel while P is under transmission

Step  3: if priority of

Step  4:     ignore and broadcast P

Step  5: else if

       priority of and

Step  6: if its current channel = CCH

Step  7:      broadcast instead of

Step  8:     broadcast after finishing broadcasting

Step  9: else if its current channel = SCH

Step  10:    broadcast first and then
