ROUTING METHOD IN SENSOR NETWORK

摘要

A routing method in a sensor network is provided to support interactive communication between a sync node and a sensor node about a user who wants to obtain a safe sensor network through extension tree routing, thereby providing efficient and safe key management mechanism and communication environment. A tree routing route is set by making each node to determine a parent node inside a sensor network based on a hello message that a sync node broadcasts. A reverse tree routing route from the sync node is set by making each node transmit a reverse route setting message to the parent node along with the tree routing route. The reverse route setting message has the sync node as a final node.
