Impact of Antenna Pattern and Link Model on Directional Neighbor Discovery in 60 GHz Networks
60GHz radio is a very attractive technology for short-range wireless communication due to its capability to provide Gbps data rate. To address the Neighbor Discovery (ND) problem in 60GHz networks, the authors propose a novel analytical framework to investigate the ND performance. The main difficulty in modeling the ND process in a 60 GHz network is the involvement of the directional antennas with gain differences between the antenna's main lobe and side lobes. Different antenna modes - directional or omni-directional - coupled with different ND mechanisms make the analytical study demanding. In this paper, they propose a comprehensive theoretical model to demonstrate the performance of ND processes using one-way ND and handshake-based ND mechanisms.
