Abstract: Mobile elements are used in wireless sensor network to increase the longevity of network by minimising the overloading of one hop sensors. Mobility has proven very useful in reducing the formation of energy holes by balancing the load among all the sensor nodes. The paper proposes exploiting mobile cluster heads to move along a predetermined trajectory to collect data. As autonomous moving strategies impose heavy overhead and data latency issues, predetermined trajectories have proven successful in improvising the lifespan of network. The contributions of the paper are twofold. First we have proposed a predetermined trajectory model along with a cluster formation procedure for the cluster heads to involve in data collection. The cluster heads stop for a fixed time duration 't' at each rendezvous point for data collection. Second we have proposed a mathematical formulation to optimise the sojourn time duration of the cluster head based on the one hop residual energy of the sensor nodes.
