This paper considers the navigation of a solar-powered UAV for securing communication with an intended node in the presence of eavesdroppers in urban environments. A multi-objective optimization path planning problem is formulated, which jointly considers UAV residual energy, the time period enabling secure communication with the intended node, and the time to reach the destination. Buildings in urban environments add challenges to the problem, as they may block the transmitted signals and create a shadow region where UAV cannot harvest energy. A rapidly exploring Random Tree (RRT)-based path planning scheme is presented, which accounts for the negative impact of the buildings and delivers an excellent path balancing the considered goals.
