Problems solved by technology

In fact, because the wireless network transmission is easily affected by the environment and interference, the single control node mode can no longer meet the performance and stability requirements of the network control system, which seriously restricts the combination of the mutual advantages of the wireless network and the network control system. How to use Multiple distributed control nodes will be an effective way to solve this severe problem, but at the same time, the openness and random dynamic characteristics of wireless networks bring great challenges to the optimal selection of control nodes
