Target coverage problems have received much attention in recent years. In a large monitoring environment where targets are distributed over an entire monitored region, deploying static sensors leads to high hardware costs because a high number of sensors may be required to achieve network connectivity. This paper considers the target-patrol issue where a set of mobile data mules (DMs) are dispatched...
Target Tracking is one of the most important issues in wireless sensor networks. In a densely deployed wireless sensor networks (WSNs), all sensors participating in the monitoring task can provide full coverage but might inefficiently consume their energies if the target did not enter the region. This paper proposes an energy-saving and quality-guaranteed target tracking mechanism, called EQTT, which...
