Problems solved by technology

However, it has the following limitations: the first is the limited transmission capacity. Wireless sensor networks transmit data through radio waves. At the same time, there is mutual interference between the signals, and the signal itself is constantly attenuating; the second is the limitation of energy. In order to measure the specific value of the real world, each node will be densely distributed in the area to be tested, and the energy will be supplemented artificially. The method is no longer suitable, each node must reserve energy for long-term use, or draw energy from the outside; the third is the issue of security, wireless channels, limited energy, and distributed control make wireless sensor networks more vulnerable to attack
