Wireless mesh networks (WMNs) have been increasingly used to carry multimedia traffic with flow requirements. The performance of multi-radio multi-channel (MRMC) WMNs largely depends on the routing and channel assignment. Because routing and channel decisions are coupled, they need to be jointly optimized to achieve the best performance. This is the so-called routing and channel assignment (RCA) problem,...
Long Term Evolution-Advanced (LTE-A) is a new radio access technology that is expected to provide better experience among the mobile cellular users. It delivers multimedia services using packet switching technology. Therefore, intelligent design of packet scheduling for the LTE-A to provide Quality of Service (QoS) comparable to fixed line services becomes crucial. However, packet scheduling over...
Resource allocation play an important role in service composition for cloud-based video surveillance platform. In this platform, the utilization of computational resources is managed through accessing various services from Virtual Machine (VM) resources. A single service accessed from VMs running inside such a cloud platform may not cater the application demands of all surveillance users. Services...
Wireless Multimedia Sensor Networks (WMSN) are new and emerging networks of wirelessly connected devices, which consist of cameras, microphones, infra-red sensors, scalar sensors and others. These networks are fast gaining popularity due to their potential to be incorporated in various applications, such as, traffic monitoring, border surveillance, smart homes, environment and habitat monitoring,...
Transmission of video and imaging data requires both energy and QoS aware routing in order to ensure efficient usage of the sensors and effective access to the gathered information. In large-scale networks with a large number of sensor nodes, multiple sink nodes should be deployed to increase the manageability of the network and also to reduce the energy dissipation at each node. In this paper we...
If network congestion occurs, packets cannot be delivered timely, the data rate decreases significantly and the required level of QoS cannot be achieved for all nodes. Especially in Home Area Networks (HANs) with limited uplink bandwidth for internet access, congestion is a major problem. Different approaches for congestion aware link sharing and QoS provisioning exist. Also the Distributed Fair Congestion...
As the demand for multimedia traffic via satellite increase, quality of service (QoS) management becomes more crucial, especially for the effective utilization of on-board switching capabilities of multi-beam satellite system. For multimedia services, parameters related to different requirements need to be evaluated in terms of delay, jitter, blocking probability and burstiness. This paper is on the...
The DVB-T or Digital Video Broadcasting — Terrestrial will be the next standard of television broadcasting in Indonesia, replacing its predecessor the analogue one. This standard will create a new department in the broadcasting system which will be known as “Penyelenggara Multiplekser”. This department has a responsibility to multiplex all of the existed programs into a single stream ready to be modulated...
The last decade has seen the emergence of the concept of converged IP networks, which make use of a multitude of heterogeneous core and access networks. We have also witnessed the proliferation of numerous multimedia services such as audio/video streaming, VoIP, or IPTV. The users' satisfaction and the perceived quality are being recognized as crucial for the successful provisioning of these services...
In Wireless Multimedia Sensor Networks (WMSNs), data fusion and collaborative in-network processing operations often require effective multimedia synchronization control. Extensive researches have been done in the traditional networks. Most of these works assume that there exists a powerful synchronization controller in the network. However, for WMSNs, the in-network processing of the multimedia content...
Due to the growing popularity of smart phones, video streaming on wireless network has increasingly become a pivotal application for customers. Comparing with wired network, packet loss and transmission delay are two of the major hurdles to achieve a friendly user experience. In this paper, we propose an adaptive re-transmission scheme in the radio layer based on the priority of each frame, which...
This paper concentrates on the problem of minimizing network coding resources with end-to-end delay and delay variation constraints in multimedia network. Network coding resources optimization problem has proved to be NP-hard, and the introduction of delay constraints makes it more complicated to be solved, since essentially the single problem of constructing such delay constrained tree without combining...
A QoS-aware and priority-based multipath routing (QoSPMR) algorithm is proposed for WMSNs. The proposed algorithm comprehensively considers the categories and priorities of multimedia streams, the residual energy of nodes, the local link reliability between nodes, the local congestion status and the distance from the candidate next hop nodes to the sink. Simulation results show the QoSPMR algorithm...
Energy consumption in wireless sensor networks (WSN) was always a basic constraint to respect. But, with the appearance of Wireless Multimedia Sensor Networks (WMSN), another basic constraint comes from added, which is the traffic performance in terms of delay, throughput, and Packet Delivery Rate (PDR). The choice of channel access method can help us to better respond the two constraints in WMSN...
Wireless multimedia applications are major services of next generation wireless networks. This paper is one of the first to study the efficient utilization of network resources for increasing the number of concurrent multimedia flows when a channel becomes saturated. We theoretically study the flow scheduling policy with the motivation of ameliorating the trade-off between limited channel resources...
One of the today challenges for the mesh networks researches is reliable transmission of multimedia traffic. This traffic demands high quality of service (QoS), to provide which it is suitable to use Mesh Coordinated Channel Access (MCCA) — the novel medium access method described in IEEE 802.11s. According to MCCA, mesh stations (STAs) set up periodic reservations; if all STAs in the network support...
Development of multimedia from year to year increasing with the growing support of computer networks such as wireless LAN (WLAN) as a media intermediary. The one of method is streaming multimedia delivery over the internet from the server to the client to respond to client requests to a video and audio contained in a computer network. Factors that affect the streaming is bandwidth. These factors may...
The Internet is rapidly evolving towards a multimedia service delivery platform. However, existing Internet-based content delivery approaches have several disadvantages, such as the lack of Quality of Service (QoS) guarantees. Future Internet research has presented several promising ideas to solve the issues related to the current Internet, such as federations across network domains and end-to-end...
In this paper, we treat the problem of delay constrained multimedia applications over Cognitive Radio (CR) networks under Binomial primary traffic arrival. Secondary Users (SUs) share the spectrum holes using the TDMA method based on the Opportunistic Spectrum Access. Primary traffic interruptions and the concurrent secondary access to spectral resources are major reasons for packet losses. Thereby,...
In this paper, we present an adaptive algorithm to deploy or re-deploy wireless mobile relays in pervasive environments. To that end, we simulate a simple scenario where a wireless router moves between two static nodes, a source and a destination of multimedia traffic. The mobile relay and both static nodes are in line of sight. The mobile router can move on the straight line between source and destination...
