ABSTRACT:
A geographically adjacent access router discovery system discovers geographically adjacent access routers through a distributed process in which mobile node(s) associated with a current access router may receive beacon signals from geographically adjacent access points. A link layer ID included in the beacon signals may be used by the system to identify corresponding geographically adjacent access routers. Network layer addresses of geographically adjacent access routers may be mapped to corresponding link layer IDs and cached by the system. The cache may be used to identify a network layer address from the link layer ID received in a beacon signal.
