Abstract
A method is disclosed for discovering communication devices. The method includes broadcasting, with a first communication device, a message that can be detected by one-hop neighbors. The first communication device listens for data indicating that it has at least one two-hop neighbor, and constructs and stores a list of its one-hop and two-hop neighbors. In addition, the method may also include selecting a subset of the set of one-hop neighbors such that all of the two-hop neighbors of the first communication device can be reached by the first communication device through the subset of one-hop neighbors. Then the selected subset is stored on a list on the first communication device. Next, the first communication device broadcasts to one-hop neighbors in the selected subset, the data indicating that a one-hop neighbor is part of the selected subset. The method also allows the discovery of multi-hop neighbors by utilizing the selected subset.
