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

Algorithm 1

Cluster formation process.

Step  1: vehicle x broadcasts cluster joining request message

Step  2: if request acknowledged

Step  3:    vehicle joins the cluster

Step  4: if no response

Step  5:     initiates cluster formation process

Step  6: end if

Step  7: end if

Step  8: vehicles receives cluster joining request

Step  9: vehicles broadcast

Step  10: if speed of

Step  11:    add to cluster class 4

Step  12: else

Step  13: if speed > 20 and ≤ 30

Step  14:    add to cluster class 3

Step  15: else

Step  16: if speed > 30 and ≤ 40

Step  17:    add to cluster class 2

Step  18: else

Step  19: if speed > 40

Step  20:    add to cluster class 1
