Neighbor Discovery (ND) is a basic and crucial step for initializing wireless ad hoc networks. A fast, precise, and energy-efficient ND protocol has significant importance to subsequent operations in wireless networks. However, many existing protocols have high probabilities to generate idle slots in their neighbor discovering processes, which prolongs the executing duration, and thus compromises their performance. The authors propose a novel randomized protocol FRIEND, a pre-handshaking neighbor discovery protocol, to initialize synchronous full duplex wireless ad hoc networks.
