ROUTING METHOD AND SYSTEM BASED ON LOCATION INFORMATION

摘要

A location information-based routing method and a system therefor are provided to reduce the routing overhead caused by the broadcasting of a control message by removing the route searching procedure which is performed to establish a path to a destination node before the communication in the Ad-hoc network. An ad-hoc node receiving a response message adds its own information to the response message, and then transmits the response message to a gateway(S702). The gateway collects information about the lowest ad-hoc node and the other ad-hoc nodes from response message received from the ad-hoc nodes. Packets are transmitted through routing by the greedy forwarding based on the whole topology information which is collected by the gateway and the local topology information which is collected by the ad-hoc nodes(S706~S710).
