Abstract
A method of setting a routing path for transmitting a packet from a source node to a destination node in a wireless multi-hop network including plural nodes and plural links for connecting two nodes with each other. The method includes calculating carrier sense interference weights representing carrier sense interference related to the respective links and combining the carrier sense interference weights of the links included in at least one specific path connecting the source node with the destination node. The method further includes calculating hidden node weights representing hidden node problems related to the respective links and accumulating the hidden node weights of the links included in the path. The method further includes calculating a metric value for the specific path by combining the carrier sense interference weights and the hidden node weights, and determining the specific path with the least metric value as the routing path.
