“…However, the network would indicate problems beyond its direct control to completely mitigate, such as weaknesses in sensor or radio coverage or depleted energy reserves, which might require the user to deploy replenishment nodes. [6], [7], [8], [9], [10], [11] A further critical aspect of the distributed sensor network is that each node will contain its own power source. Typically, this will take the form of batteries; however, energy harvesting methods such as use of solar cells are also possible.…”
