METHOD AND RECORDING MEDIA FOR MAINTAINING ROUTE IN TREE TOPOLOGY NETWORK

摘要

PURPOSE: A method for keeping the root in a tree ontology network and a recording medium thereof are provided to effectively reconnect to network when cutting off the link. CONSTITUTION: A first node searches peripheral node through scan when cutting the link with a second node(S202). The first node determines whether a parent node(a third node) of a second node among the searched peripheral node exists or not by using predetermined algorithm(S204). If the third node of the second node exists, the first node selects the third node to their parent node(S206). The third node renews the neighbor table by relating with link cut of the second node and registration to their node of the first node.
