If more sensors are deployed to increase coverage, then the coverage area increases, but the cost increases
Solution Approach 1:
The patent formulates the sensor position optimization as a parameter optimization problem where the objective function combines coverage maximization with cost minimization. By using quantum algorithms to optimize the parameters (sensor positions and orientations), the system finds configurations that achieve maximum coverage with the minimum number of sensors, thereby reducing the quantity of sensors required while maintaining or improving coverage area.

If sensors are positioned to maximize coverage, then the coverage is optimized, but the computational time increases
Solution Approach 1:
The patent employs quantum algorithms that can evaluate multiple sensor configurations in parallel through quantum superposition. The VQE algorithm prepares quantum states representing different sensor positions and evaluates their coverage properties simultaneously, allowing the system to find optimal configurations much faster than classical methods while achieving the same coverage optimization.
