Abstract
Reducing the energy holes by using multiple mobile sinks and reducing the one hop sensor energy consumption is one of the important research issues in wireless sensor network. The proposed work focus on deploying multiple mobile sinks to move across a predetermined trajectory for data collection. The network area is divided into triangular partitions and the mobile sinks are allowed to move along triangular partitions. The work proposes a clustering protocol to form data collection trees. The contribution is extended further by formulation an optimization model for improvising the sensor network lifetime. The mobile sinks are allowed to travel along the predetermined trajectory and stop at each sojourn location for an optimal time location. The optimization model considers the one hop residual energy and energy consumption of the individual sensor. Simulation experiments showcase better performance of the proposed work in comparison with existing model.
