The present invention provides a method and system for managing the connections of multiple stations in a Wi-Fi mesh network, using station steering to optimize the overall throughput of the network.

The stations are proactively steered depending on the link quality, the network topology and wireless medium occupation, as well as the different equipment capabilities, to ultimately provide the best available throughput.

This invention also aims to detect crowded Access Points or frequency bands, and steer stations accordingly towards an efficient load control and traffic management between nodes/Access Points and improved quality of experience.

The present publication relates to the wireless signal technologies, and provides methods and systems for wireless signal reinforcement and wireless network load sharing and following. The method for wireless signal reinforcement comprising: a mobile wireless access point moving and measuring the wireless signal strength of other wireless access points received at the location the mobile wireless access point passes through; determining a first location where the wireless signal needs to be reinforced according to the measurement result; and the mobile wireless access point moving to a second location according to the first location, so that the strength of the wireless signal transmitted by the mobile wireless access point from the second location to the first location exceeding the strength of the wireless signal of other wireless access points at the first location. The implementation of the publication can adaptively change the distribution of the environment wireless signals as the environment changes, and realize efficient coverage of wireless signals at low cost.

A path selection apparatus in a sensor tree includes a node moving unit that selects a first node in the sensor tree, and moves a second node to under a third node in the sensor tree if the total number of packets transmitted and received in the sensor tree is reduced as a result of the second node being moved to under the third node, the first node having a child node under the first node, the second node being located under a subtree of which a vertex is the first node, the third node not belonging to the subtree. If nodes under the subtree of which the vertex is the first node do not include anode that reduces the total number of packets as a result of being moved, the node moving unit moves a node that is included in the nodes under the subtree and does not change the total number of packets, to under the third node.
