Abstract
Devices and methods used in a wireless network employing geographical routing using virtual node locations. Such virtual node locations can be computed by a central computer that gathers information from some or all of the nodes. Each node may, for example, identify itself and its neighbors and provide a value indicative of the radio frequency (RF) distance to such neighbors. Examples of RF distance indicators include, but are not limited to, received signal strength indication (RSSI) and packet success rate (PSR). Geographic coordinates for none or some of the nodes may also be used to determine the virtual coordinates.
