Delay-Tolerant Networking (DTN) is an approach to computer network architecture that seeks to address the technical issues in heterogeneous networks that may lack continuous network connectivity. Due to the lack of continuous communications among mobile nodes and possible errors in the estimation of nodal contact probability, convergence and stability become major challenges in distributed clustering in DTMN. Clustering significantly reduces the energy consumption of a cluster. In this paper, a cluster based routing protocol for Delay-Tolerant Mobile Networks (DTMNs) is used. Exponentially Weighted Moving Average (EWMA) scheme is employed for on-line updating nodal contact probability, with its mean proven to converge to the true contact probability.
