Abstract

The huge demand for high data rate machine-to-machine (M2M) services has led to the use of millimeter Wave (mmWave) band communications with support for a multi-Gbps data rate through the use of directional antennas. However, unnecessary sector switching in multicast transmissions with directional antennas results in a long delay, and consequently a low throughput. We propose asymmetric directional multicast (ADM) for capillary M2M to address this problem in mmWave communications. ADM provides asymmetric sectorization that is optimized for the irregular deployment pattern of mulicast group members. In ADM, an M2M gateway builds up asymmetric sectors with a beamwidth of a different size to cover all multicast group members with the minimum number of directional transmissions. The performance of ADM under various simulation environments is evaluated through a comparison with legacy mmWave multicast. The results of the simulation indicate that ADM achieves a better performance in terms of the transmission sectors, the transmission time, and the aggregate throughput when compared with the legacy multicast method.

Summary

Introduction

Capillary machine-to-machine (M2M) refers to networking technologies that provide devices with wireless connectivity in a local area by using various communications standards, includingBluetooth Low Energy (BLE), ZigBee, Wi-Fi, and WiGig [1,2]. The scope of their use has progressively extended to higher data rate applications due to the increasing demand for real-time streaming of high-definition television (HDTV), high-speed data transfer, and wireless mmWave band communication can support a multi-Gbps data rate with directional antennas, and it can be used for various M2M services, for high data rate indoor services such as ad hoc conferences, smart classrooms, and telecasts [12,13] In these applications, the devices that users have can be divided into multiple service groups, and each group might request different multimedia contents such as video streaming, presentation material from a dedicated local server (e.g., projector, presenter’s laptop). The local server should support a sufficient data rate to multiple groups
