BACKGROUND Technical Field The present disclosure relates to a network management system and a method thereof. More particularly, the present disclosure relates to a mesh network management system based on wireless sensing and a method of managing a mesh network based on wireless sensing. Description of Related Art A wireless fidelity (WIFI®) is one of the main communication technologies that people usually use to surf the Internet. A mesh network is a method to transmit data and the controlling commands between network nodes through dynamic routing. The mesh network can include a plurality of access points (AP) that can be connected to each other through a wireless network, and so the mesh network is able to extend the coverage range of wireless network communication area in addition to allowing client devices to be connected to anywhere while maintaining the network connection quality when many people are online. However, with the client devices in wireless network becoming more popular, the number of mesh routers in mesh network also increases. When the user left the mesh network, the mesh routers are still in work mode and continue to consume power. On the other hand, when the mesh network is at home or work environment and there is no one around, there is a possibility of malicious connection or data snooping by other people. In view of this, a mesh network management system and a method thereof that can detect in real time whether someone is present in the environment so as to control the work mode of mesh routers are indeed highly anticipated by the public and become the goal and the direction of relevant industry efforts.
