A wireless sensor network node has a transmitter/receiver range of 2 m and many such sensors need to be installed in a nuclear plant building of a size 50 m×50 m with a height of 25 m.

Can you think of an efficient arrangement of the sensor arrays? How many sensors are required? Explain clearly. Consider different coverage geometries for the sensors, i.e., triangular, circular, hexagonal, square, etc. and multiple layers of sensors to cover the entire volume. Would you want all the sensors to have the same processing capabilities, or can you find compelling reasons why some sensors should be designated “super sensors” and have more processing capabilities?
