The invention discloses a location aided routing method applied to a
wireless Mesh network. The method comprises the following steps that: distributed nodes in the
wireless Mesh network acquire the location information of the nodes, and transmit the location information to other nodes in the network in a broadcast form; each node in the network maintains a mapping table L-Mac of Mac addresses and the location information in the form of a Hash link table; a source node calculates a circular search domain according to the location information in the L-Mac as well as the
moving speed and moving direction of the source node before
initiation of routing; when a routing request frame is received, an intermediate node judges whether or not the intermediate node is in the request domain, if so, forwards the routing request frame, otherwise, discards the routing request frame; after receiving the request frame, a destination node transmits a routing response frame to the source node by selecting a path with a small
moving speed domain accumulated value; and after receiving the response frame, the source node starts transmitting data packets. Through adoption of the location aided routing method, the location information is utilized fully. Compared with a conventional routing method, the method has the advantages of smaller time
delay and lower resource occupation.
