The wireless sensor networks find their applications in agriculture, military, disaster prone area etc. The nodes in the network are run by smaller batteries which need to be utilized in a way that they can work for longer time duration. Unmanned aerial vehicles are used with such networks for data collection purposes to increase the network lifetime. The trajectory of the UAV needs to be optimized such that the network can give desired output. This paper proposes a modification to the existing spiral path planning algorithm and is based on the fact that UAV if moved along the square (inscribed in the circle) will have less trip distance. The performance of the network was compared based on trip time, tour length and remaining energy of the network. These parameters showed an improvement over the existing scheme.
