Gathering information in a sensing field of interest is a fundamental task in wireless sensor networks. Current methods either use multihop forwarding to the sink via stationary nodes or use mobile sinks to traverse the sensing field. The multihop forwarding method intrinsically has the energy hole problem and the mobile sinks method has a large gathering latency due to its low mobility velocity. In addition, all the mobile sinks methods assume unlimited power supply and memory which is unrealistic in practice. In this paper, the authors propose a new approach for information gathering through a Mobile Aerial Sensor Network (MASN).
