Geographic routing

<p>Geographic routing (also called georouting or position-based routing) is a <a href="/facts/Routing/Ml6MVCaC">routing</a> principle that relies on <a href="/facts/Geographic_position/RkjfcY6k">geographic position</a> information. It is mainly proposed for <a href="/facts/Wireless_network/yr4SWTdl">wireless networks</a> and based on the idea that the source sends a message to the geographic location of the destination instead of using the <a href="/facts/Network_address/W7RQVwBr">network address</a>. In the area of <a href="/facts/Packet_radio/90L290N1">packet radio</a> networks, the idea of using position information for routing was first proposed in the 1980s for interconnection networks. Geographic routing requires that each <a href="/facts/Node_(networking)/LBp2vNcJ">node</a> can determine its own location and that the source is aware of the location of the destination. With this information, a message can be routed to the destination without knowledge of the <a href="/facts/Network_topology/rBYE0kke">network topology</a> or a prior route discovery.
