“…When the data rate was equal to 11Mbps, the Packet End-to-End Delay stayed in the range of 0.063 seconds during the time the video traffic was receiving. This time delay was considered to be acceptable level and it allowed the Video MPEG-2 traffic to be received with low packet loss ratio as proposed by [27] and [22].…”

“…After 108 seconds the delay increasing sharply to 0.352 seconds and kept increasing until it reached 0.489 seconds. This delay while using the 2Mbps data rate was considered to be an unacceptable delay and the video session could not be recovered due to high packet loss ratio [27] and [22].…”

“…Whereas, Video (MPEG-2 CIF/SIF (625) 352*288 pixels) has a minimum channel capacity (data rate) of 6Mbps. The reason behind selecting a higher minimum channel capacity for video applications is that video traffic is considered to be a heavy traffic with high numbers of frame sequences (I, P and B frames) [27].A higher data rate for video applications is required. 9 …”

In heterogeneous vehicular networks, the most challenging issue is obtaining an efficient vertical handover during the vehicle roaming process. Efficient network selection process can achieve satisfactory Quality-of-Service for ongoing applications. In this paper, we propose an Intelligent Network Selection (INS) scheme based on maximization scoring function to efficiently rank available wireless network candidates. Three input parameters were utilized to develop a maximization scoring function that collected data from each network candidate during the selection process. These parameters are: Faded Signal-to-Noise Ratio, Residual Channel Capacity, and Connection Life Time. The results show that the proposed INS scheme is more efficient at decreasing handover delays, End-to-End delays for VoIP and Video applications, packet loss ratios as well as increasing the efficiency of network selection processes in comparison with the state of the arts.

Wireless Mesh Networks for In-Home IPTV Distribution

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.

The evolution and popular adaptation of drone technology in diverse applications has necessitated advancement of UAV communication framework. UAVs inherently support features like mobility, flexibility, adaptive altitude, which make them a preferable option for dynamic surveillance of remote locations. Multiple UAVs can cooperatively work to accomplish surveillance missions more efficiently. However, the intermittent network connectivity and the limited onboard energy storage impose a great challenge on UAV-assisted remote surveillance. This paper presents an Energy-efficient Collaborative Multi-UAV Surveillance (ECMS) system for surveillance of inaccessible regions. The system employs an optimal Multi-UAV Collaborative Monocular Vision (MCMV) topology to facilitate the surveillance with zero blind spot using minimum number of drones. We also propose an application-aware Multi-Path Weighted Load-balancing (MWL) routing protocol for handling congestion by distributing traffic among all available resources in UAV network and adaptively selecting the of source datarate (i.e. switching video resolution). The simulation results demonstrate that the proposed surveillance system achieves coverage with lesser number of UAVs compared to the existing systems. It also achieves higher throughput, higher packet-delivery ratio, higher residual energy of UAVs, and lower end-to-end delay.INDEX TERMS Unmanned aerial vehicle, remote surveillance, UAV network topology, multi-path routing, load balancing.
