1. A mesh routing method, comprising: broadcasting, by each node constituting a wireless AD-HOC network, a beacon message loading neighbor node information on a beacon payload; generating, by a node receiving the broadcasted beacon message, a neighbor node table by adding the neighbor node information loaded on the beacon payload to the neighbor node table; and performing, by a source node attempting to transmit data or commands, mesh routing based on a neighbor node table generated for the source node using a corresponding neighbor node information extracted from the beacon payload.
