Recently, much research effort has been devoted to employing mobile chargers for energy replenishment of the robots in robotic sensor networks. Observing the discrepancy between the charging latency of robots and charger travel distance, we propose a novel tree-based charging schedule for the charger, which minimizes its travel distance without causing the robot energy depletion. We analytically evaluate...
The introduction of mobile elements has created a new dimension to reduce and balance the energy consumption in wireless sensor networks. However, data collection latency may become higher due to the relatively slow travel speed of mobile elements. Thus, the scheduling of mobile elements, i.e., how they traverse through the sensing field and when they collect data from which sensor, is of ultimate...
Data collection with mobile elements in wireless sensor networks brings in new opportunities to reduce and balance the energy consumption of sensor nodes, however, it may result in high data collection latency. The optimal scheduling of mobile element's limited mobility is of great importance to reduce this latency, and a lot of research efforts have been made on it. Focusing on the on-demand data...

Thus the scheduling of mobile elements, i.e., how they traverse through the sensing field and when they collect data from which sensor, is of ultimate importance and has attracted increasing attention from the research...
