“…Call admission control based QoS provisioning for video traffic in a network environment, e.g., ATM and cellular networks, was investigated in [7,8], using either an effective bandwidth approach or a measurement-based approach. For resource management in mmWave networks, an exclusive region (ER) based resource allocation scheme was proposed in [9] to exploit the spatial multiplexing gain of mmWave WPANs supporting persistent traffic flows. The optimal ER size towards the maximum capacity of mmWave UWB networks with omni-directional and directional antennas was analytically obtained in [10].…”

There is an increasing interest in 60 GHz millimeter-wave (mmWave) communication technologies for multi-Gigabit wireless personal area networks (WPAN), aiming to support broadband multimedia applications. Internet Protocol TV (IPTV) is an emerging killer application which requires high data rate and stringent quality of services (QoS) in terms of delay and packet loss. In this paper, we propose a method to efficiently support high definition video flows in a mmWave-based WPAN with QoS guarantee, considering the characteristics of both the IPTV traffic and the mmWave communication technology. We first quantify the effective bandwidth of IPTV video sources using a simple, two-level Markov traffic model. Considering the overheads of the protocol stack in mmWave WPANs, we then quantify the minimum channel time needed for each IPTV flow. Since mmWave-based WPANs will deploy directional antennas to not only extend the transmission range, but also reduce the interference level to neighboring flows, we further propose an admission control scheme and scheduling algorithm to improve the network resource utilization by taking advantage of concurrent transmissions. Extensive simulations with NS-2 using real video traces have validated our analysis and demonstrated the efficiency and effectiveness of the proposed schemes, which will be an enabling technology for future mmWave-based WPANs supporting IPTV services.

“…For a successful transmission, a transmitter-receiver pair has to be capable of interference-free communication. Thus, the concept of an exclusive region (ER) was introduced in [7], and it is defined as follows: each frame consisting of a transmitterreceiver pair has an ER around the receiver. The transmitters of all of the other frames engaging in simultaneous transmission must be located outside of the ER.…”

“…There has been research in using directional antennas: directional neighbor discovery (D-ND) [4], resource allocation policies and scheduling algorithms [5], [6], and mmWave WPANs [7]- [9]. Analysis of the CSMA/CA protocol can be found in many papers based on various standards: IEEE 802.11 [10], [11], IEEE 802.15.4 [12], IEEE 802.15.3 [13], and 802.15.3c [14], [15].…”

In this paper, the directional carrier sense multiple access/collision avoidance (CSMA/CA) protocol in the immediate acknowledgement mode for IEEE 802.15.3c is analyzed under saturation environments. For the analysis, a sensing region and an exclusive region with a directional antenna are computed probabilistically and a Markov chain model in which the features of IEEE 802.15.3c and the effects of using directional antennas are incorporated is analyzed. An algorithm to find the maximal number of concurrently transmittable frames is proposed. The system throughput and the average transmission delay are obtained in closed forms. The numerical results show the impact of directional antennas on the CSMA/CA media access control (MAC) protocol. For instance, the throughput with a small beamwidth of antenna is more than ten times larger than that for an omnidirectional antenna. The overall analysis is verified by a simulation. The obtained results will be helpful in developing an MAC protocol for enhancing the performance of mmWave wireless personal area networks.

“…After the beamwidth of each adequate sector has been obtained in this way, it becomes possible to obtain the most suitable data rate for multicast data transmission. The most suitable data rate can derived by using the relation formula between beamwidth and average received power [5], is given by…”

This paper proposes the use of a beam steering scheme for establishing multicast communication between millimeter-wave devices in 60 GHz wireless networks. It should be noted that beam steering is a key technique for the millimeter-wave multicast devices scattered omni directionally. We derive the analytical expression for the dynamic beamforming, and we observe the impact of the number of beams. Extensive simulation results show that dynamic beam steering enable more efficient sectoring than fixed beam steering.
