This letter presents a new stable clustering architecture to reduce the number of re-clustering in MANET. Since some existing stable clustering schemes based on measured metric have certain deficiency in negative effect caused by nodes moving fast or causing ping pong effect, we introduce average connection time as major parameter to form as well as maintain cluster structure over the entire networks. From simulation results it is clear that average connection time is more adequate parameter for stable cluster architecture than other measured factors, resulting in fewer number of cluster changes than previous schemes.
