Conference Title: GLOBECOM 2018 - 2018 IEEE Global Communications Conference Conference Start Date: 2018, Dec. 9 Conference End Date: 2018, Dec. 13 Conference Location: Abu Dhabi, United Arab Emirates Device-to-device (D2D) communication is a novel paradigm in cellular networks and is being considered as one of the primary technologies for the upcoming fifth generation (5G) standard for cellular communication. On a similar note, millimeter wave (mmWave) communication is also one of the very enablers for 5G. For D2D communication, neighbor or device discovery is a fundamental problem in mmWave networks because of the use of highly directional antennas. In this paper, we consider this fundamental neighbor discovery problem: How can nodes discover their neighbors quickly and efficiently for communication in decentralized networks, without any prior coordination and with heterogeneous antenna configurations. We propose a novel D2D neighbor discovery algorithm that uses the idea of necklaces to reduce the worst case discovery delay as compared to the previous approaches. The results from numerical simulations confirm that the proposed algorithm leads to faster and energy efficient neighbor discover as compared to the existing algorithms.
