Wireless Peer Discovery in Heterogeneous Half-/Full-Duplex Networks

In this letter, we investigate wireless peer discovery, which finds neighbor nodes to establish connections among peers. Unlike half-duplex (HD) nodes, which operate in either one of transmitting and receiving modes, full-duplex (FD) nodes can transmit and receive signals simultaneously, and thus th...

Description
Summary:In this letter, we investigate wireless peer discovery, which finds neighbor nodes to establish connections among peers. Unlike half-duplex (HD) nodes, which operate in either one of transmitting and receiving modes, full-duplex (FD) nodes can transmit and receive signals simultaneously, and thus the average number of discovered peers (ADP) can be enhanced by employing the FD nodes. First, we analyze the ADP modeling the spatial distribution of nodes as Poisson point processes, and then provide interesting observations on the ADP. The ADP is relevant to the transmission probability (TP), which means the probability that an HD node transmits at a given time slot. Therefore, an efficient algorithm is proposed to identify the TP, which maximizes the ADP by considering fairness between the number of discovered HD and FD nodes. Numerical results validate the accuracy of the analysis and efficiency of the proposed method.
