The application of Multihop Cell phone-based Sensor Network (MCSN) technologies for the Data gathering service has brought new challenges in maintaining communication clusters of Cluster heads for long time durations. Stable clustering methods reduce the reclustering frequency in MCSN and provide for a more energy-efficient hierarchical network topology. The stability is defined in terms of Dominating set updates or reclustering frequency as average number of cluster formation per unit time. During creation of MCSN clusters, each Cell phone chooses a head cell phone to send the sensed data. In this paper, we improve cluster stability by the addition of one pause time-based weighting parameter to a well-known weighted clustering algorithm (WCA). The WCA uses current mobility index of mobile nodes to predict the stability of the network. Newly introduced parameter is related with cell phone user’s mobility-specific pause time distribution.
