Abstract
Disclosed relates to an automatic fall behind warning method and system applied in a group activity environment. Each individual in the group corresponds to a node and all of such nodes form an independent network. The method initializes an outside node table for the group and gets a link quality index table (LQI table) among the nodes on the network. A table specifying outside and inside nodes for the network topology is generated via an algorithm. Then the method checks if there is a node being disappearing from the outside nodes of the generated table. If not, it updates the outside node table and continues to get a newest LQI table. If so, the node falls behind is confirmed and a warning notice is automatically generated once the disappearing node is not an inside node is verified. Otherwise, the method returns to the step of updating the outside node table.
