“…To support 1080p HD video streaming, we use 1.65 Gbps data rate and a 29.63 μs transmission interval since it requires more than 1.485 Gbps data rate and less than 29.64 μs transmission interval [ 28 ]. Considering an HD video streaming application for three MGs, we configure packet of different sizes for each MG, which represents the chunk of data for different video streaming content [ 29 , 30 , 31 , 32 ]. We assume that the ADM is implemented on top of the IEEE 802.15.3c PHY layer model and its operational phases are independent with the superframe structure of IEEE 802.15.3c MAC layer.…”

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.

“…These densely deployed WiFi devices compete for access to the wireless medium [1], which can reduce the overall network throughput. Also, as the development of high quality applications such as cordless virtual reality (VR) [2], augmented reality (AR) [3] and uncompressed video streaming [4], we require the high capacity communication between the mobile client and the remote content server for graph rendering and data offloading.…”

In indoor areas such as homes and offices, high throughput communication for multiple devices is quickly becoming a necessity. Even though an access point (AP) mounted with an omni-directional antenna can cover a whole room, it cannot provide connections with high throughput throughout the room. Therefore, we propose, DiRF, a directional antenna based wireless home network designed to achieve high throughput in indoor areas with densely deployed directional APs. DiRF consists of a position based AP selection algorithm which can decrease latency accumulation caused by frequent AP switching, and a downlink packet scheduler which can reduce the downlink packet retransmissions during AP switching. We implement and evaluate DiRF with six commercial APs, each connects with a single directional antenna. Our experiments show that DiRF achieves a 3.16× TCP throughput improvement, compared to the conventional scheme that only uses one AP mounted with one omni-directional antenna.

“…The proposed allocation framework considerably increased the service coverage. Choi et al (2016) designed link adaptation policies for the streaming of high-quality 'uncompressed' video on the emerging 60-GHz multigigabits per second wireless technology. For a logical design, suitable transmission rates for the 60-GHz wireless channel environment, in order to optimize video quality and resource management, were selected.…”

Wi-Fi and LTE are commonly used for the transmission of high bandwidth data and multimedia over the internet. Providing a good quality of service in the transmission of such data over these wireless channels is challenging due to channel impairments such as noise and fading. This paper proposes three enhanced transmission schemes for audio over Wi-Fi and LTE. The first proposed scheme exploits the unequal importance of the bits generated by an MP3 codec to offer different levels of protection to them during transmission by mapping the important bits on prioritized QAM constellation bit positions. The second and third schemes use the statistical distribution of source symbols to map the bits of the encoded symbols to an SQAM constellation. For the second scheme, only systematic bits from the encoder are mapped onto the SQAM constellation. While for the third scheme, both the systematic and parity bits are mapped onto the SQAM constellation. A comparative analysis with different frequency transforms have been done. The simulation results show that the proposed schemes increase the system performance by 1-20 dB in segmented signal to noise ratio (SSNR). Using DWT further increases the gains up to 90 dB for 16-QAM at rate ½ as compared to FFT.
