Claim:
1. A method of operating a peer-to-peer (P2P) device that belongs to a P2P group, comprising: engaging in a P2P discovery procedure for discovering P2P devices that also belong to the P2P group; calculating a reachability vector that indicates each discovered P2P device in the P2P group that is within a threshold number of hops to the P2P device via a P2P interface; receiving a reachability vector for each proximate P2P device in a set of proximate P2P devices discovered via the P2P discovery procedure, each received reachability vector indicating each P2P device in the P2P group that is within the threshold number of hops to the proximate P2P device via the P2P interface; ranking the P2P device and each proximate P2P device in the set of proximate P2P devices based on the calculated and received reachability vectors; identifying a leader that is responsible for performing a floor arbitration function for a P2P session from the ranked P2P devices based on the rankings; and participating in the P2P session by exchanging media in accordance with the floor arbitration function performed by the leader.
