Design optimization of one-time-use leaping mechanism for sensor node relocation

This paper proposes a design automation method to optimize one-time-use leaping mechanism for relocating energy-constrained sensor nodes. The leaping mechanism is expected to enhance coverage and connectivity of sensor networks initially randomly deployed with minimum energy consumed. Of particular interest is proper relocation of isolated nodes under uncertain environment conditions. Specifically, we consider how the aerodynamic disturbance can be minimized with an optimized launch angle of the leaping mechanism. To construct an automated simulation and design environment, the process integration and design optimization (PIDO) approach is employed. We not only obtain an optimum solution satisfying all imposed requirements, but also demonstrate an automated design process for controlled node mobility.
