“…For the PCA-only and hybrid MAC, we use the frame service time for the largest video frame (around 327 KB) as the admission criterion, i.e., it is estimated as the number of packets being transmitted in PCA periods times the frame service time of PCA. For the DRP-only MAC, we can determine the MAS slots needed for each video by (8), and then the admission region accordingly.…”

Abstract-To reserve or not for bursty video traffic over wireless access networks has been a long-debated issue. For uplink transmissions in infrastructure-based wireless networks and peer-to-peer transmissions in mesh or ad-hoc networks, reservation can ensure the Quality-of-Service (QoS) provisioning at the cost of a lower degree of resource utilization. Contentionbased Medium Access Control (MAC) protocols are more flexible and efficient in sharing resources by bursty traffic to achieve a higher multiplexing gain, but the performance may degrade severely when the network is congested and collisions occur frequently. More and more wireless standards adopt a hybrid approach, which allows the coexistence of resource reservation and contention-based MAC protocols. However, how to costeffectively support video traffic using hybrid MAC protocols is still an open issue. In this paper, we first propose how to use hybrid MAC protocols to support video streaming over wireless networks. Then, we quantify the performance of video traffic over wireless networks with contention-only, reservation-only, and hybrid MAC protocols, respectively. Admission regions for video streams with these three approaches are obtained. Using the standard WiMedia MAC protocols as an example, extensive simulations with a commonly-used network simulator (NS-2) and real video traces are conducted to verify the analysis. The analytical and simulation results reveal the tradeoff between reservation and contention-based medium access strategies, and demonstrate the effectiveness of the hybrid approach.

The appearance of new broadband wireless technologies jointly with the ability to offer enough quality of service to provide IPTV over them, have made possible the mobility and ubiquity of any type of device to access the IPTV network. The minimum bandwidth required in the access network to provide appropriate quality 3D/2D IPTV services jointly with the need to guarantee the Quality of Experience (QoE) to the end user, makes the need of algorithms that should be able to combine different wireless standards and technologies. In this paper, we propose a network algorithm that manages the IPTV access network and decides which type of wireless technology the customers should connect with when using multiband devices, depending on the requirements of the IPTV client device, the available networks, and some network parameters (such as the number of loss packets and packet delay), to provide the maximum QoE to the customer. The measurements taken in a real environment from several wireless networks allow us to know the performance of the proposed system when it selects each one of them. The measurements taken from a test bench demonstrate the success of our system.

“…The Markov model of the video sources and that of the wireless paths can be combined together mathematically, so the queuing delay distribution and packet loss probability due to buffer overflow can be derived as functions of the number of video sources and the buffer size. Then, we can obtain the admission regions of both the wired and wireless networks with a guaranteed loss rate and delay jitter [6].…”

“…We developed a finite state Markov chain for a single hop wireless channel as follows: each state corresponds to a different SNR range and thus a different data rate, and the statetransition probabilities are chosen according to the time-correlation of the wireless channel. Similarly, a Markov chain can be developed for a multihop wireless path: each state corresponds to certain SNR ranges for each hop [6]. We use the Markov chain to model the packet-level wireless channel behavior for both the analysis and simulations.…”

nternet Protocol TV (IPTV) is considered to be the next killer application. With two-way communication capability and point-to-point distribution, each viewer can choose individual programs flexibly and at lower cost. According to a study by the Multimedia Research Group, the number of IPTV subscribers will grow from 4.3 million in 2005 to an estimated 36.8 million by 2009, with a compound annual growth rate of 72 percent, and the IPTV service revenue will increase from $740 million in 2005 to $4.6 billion in 2009, with a compound annual growth rate of 56 percent. Telecommunications service providers are racing to provide IPTV/video on demand (VoD), voice, and data -the so called triple-play services.With fiber-to-the-x (FTTx), hybrid fiber-coaxial (HFC), and state-of-the-art digital subscriber line (DSL) technologies, high quality TV programs can be delivered to the doorstep of IPTV subscribers. However, how broadband IPTV signals eventually reach displays in different places in the home is a vital, challenging problem.A broadband home network should be able to efficiently and effectively distribute IPTV traffic with a high level of user-perceived quality of service (QoS). Because rewiring the vast majority of existing houses with new wires such as Ethernet cables is prohibitively expensive, a better choice is to use "no-new-wires" and "no-wires" solutions. Competing communication technologies are emerging, using existing power line, phone line, coaxial cable, or wireless channels; for example, ultra wideband (UWB) -both wired and wireless -and IEEE 802.11n and millimeter-wave (mmWave) wireless technologies. They continue to reshape our vision of future broadband home networks.To enable ubiquitous IPTV services, wireless technologies play an important role. IPTV traffic can be distributed anywhere inside and even outside the home, using single hop or multihop wireless paths. Wireless devices can discover each other using wireless broadcast beacons and form mesh networks in a plug-and-play and distributed manner. Because of auto-configuration and self-organization, wireless mesh networks can be installed by users who lack technological expertise.According to the characteristics of different wireless technologies, we propose three different network architectures:• Homogeneous wireless-only mesh networks • Hierarchical heterogeneous wireless-only mesh networks • Combined wired and wireless mesh networks Wireless-only mesh networks and hierarchical heterogeneous wireless-only mesh networks do not have any prerequisites for current wiring in the home, so they can be deployed in existing or new homes. For heterogeneous wired and wireless mesh networks, when a wired link is available to form a reliable, high-data-rate backbone for the home network, we can use wireless technologies to further deliver IPTV traffic to the entire home ubiquitously.To compare different architectures, the admission region (the number of IPTV connections that can be supported simultaneously with QoS guarantees) is an important measure.
