Optimization of UAV path for wireless sensor network data gathering

Wireless sensor networks are used in different application areas. Many applications require network sink mobility or monitored area borders dynamicity. A possible way to accomplish these requirements is development of platforms that enable the cooperation of ground with unmanned aerial vehicles to perform sensed data gathering. In case of sparse wireless sensor network nodes location unmanned aerial vehicle path planning becomes important problem which affects system efficiency. Unmanned Aerial Vehicle path length reduction algorithm for is proposed in this work.
