Sensor nodes in Wireless Sensor Networks are energy-limited. Sensor devices are expected to operate over years with limited power supply. Thus, the energy consumption becomes important compared to throughput, latency. Efficient data collection in Wireless Sensor Networks plays a key role in power conservation. The sink mobility along a constrained path can improve the energy efficiency in Wireless Sensor Networks. However, due to the path constraint, a mobile sink with constant speed has limited communication time to collect data from the sensor nodes deployed randomly. This introduces significant challenges in jointly improving the amount of data collected and reducing the energy consumption.
