Method and system for global topology discovery in multi-hop ad hoc networks
Systems and methods are presented for topology discovery in a multi-hop ad hoc network. The method operates on two time and distance scales. Nodes periodically transmit messages to their immediate neighbors that enable the discovery of their two-hop network topologies (i.e., within two hops). Less frequently, nodes broadcast messages network-wide that enable the discovery of the global network topology at all nodes. In multi-hop ad hoc network architectures that are characterized by efficient broadcast protocols—e.g., Barrage Relay Networks—the proposed method provides a particularly efficacious means for global topology discovery.
