3(a) and 3(b) show the stability performance of Lowest-ID based 1-hop clustering, Highest-degree based 1-hop clustering, MOBIC based 1-hop clustering, MobDHop based 2-hop clustering, and DWCM based 2-hop clustering when the number of vehicles varies from 50 to 75 with a fixed S = 20 m/s and [T.sub.r] = 200 m.
These figures show that multi-hop clustering approaches (e.g., MobDHop and DWCM) form obviously fewer clusters than 1-hop clustering approaches (e.g., Lowest-ID, Highest-Degree, and MOBIC) in the simulation.
Existing research works have proposed the use of hard clustering and fuzzy based approaches for clustering the vehicles.
