Quality of Service (QoS) provisioning for wireless multimedia applications has attracted increasing research attentions. Due to limited bandwidth of time-varying wireless links and various QoS requirements of bursty multimedia applications, an effective call admission control (CAC) policy that efficiently utilizes the bandwidth is desired. We have proposed a Differentiated Queueing Service (DQS) to...
Quality of Service (QoS) routing is one of the key enabling techniques for multimedia wireless sensor networks (WSNs). However, the multi-constraints QoS routing problem is an NP-hard problem, and the computational complexity of an exhaustive search over all the paths is too high for large scale multimedia WSNs. In this paper, a novel parallel elite clonal quantum evolutionary algorithm is proposed...
Quality of Service (QoS) is considered as the standard check of a conveyance system to show provided services and its availability. For illustration application like video conferencing, voice over ip (VOIP), streaming videos, real time operation feel necessity for draconian assurance on jitter, packet loss, prioritization of services and end-to-end delay. So to overcome these issues a novel scheme...
Most of the admission control algorithms treat every admission request uniformly and hence optimize the system performance by maximizing the number of admitted and served requests. In practice, requests might have different levels of importance to the system. Requests offering high contribution or reward to the system performance deserve priority treatment. Failure of accepting a high-priority request...
In this paper, we contribute to the design and theoretical understanding of push-based content delivery in a converged broadcasting and cellular network. Specifically, we are interested in the scheme in which the most popular contents are pushed through broadcasting to alleviate the cellular data bottleneck. This strategy not only offloads the multimedia traffics from the cellular network, but also...
We propose a novel distributed on-demand routing scheme for multimedia communication through Cognitive Radio Networks (CRN). The basic technique is to effect the multimedia communication through multiple routes between the source and the destination nodes based on Sample Division Multiplexing (SDM) [2] such that the sum of flow along all such routes is equal to the required flow between the source-destination...
In this paper the two implementations of RObust Header Compression (ROHC), namely ROHCv1 (RFC 3095) and ROHCv2 (RFC 5225), are evaluated in terms of potential throughput increase and complexity for wireless IP networks and compared with each other for different multimedia streams. In order to compress the header information to a minimum, RoHCv1 has been proposed some years back and recently RoHCv2...
The mobile device usages in last decade grown enormously due to the variety of applications with video based contents. The video delivery through the internet is highly focused because of heavy demands from the mobile users. We take various techniques involved in video streaming in wireless networks. The different constraints and different methods have been studied with their merits and demerits and...
This paper introduces an efficient and fair bandwidth allocation strategy called fair service for multiuser multimedia communication over Heterogeneous Networks. Its purpose is to fairly allocated bandwidth to all the users with different video service characteristics and ensures their efficiency at the same time. The proposed fair service bandwidth allocation strategy is formulated as a convex optimization...
The Transmission of multimedia content typically has bandwidth, delay and loss issues. Video compression, layer, media distribution services, streams servers, synchronization technique and synchronization protocols for streaming are major areas of research. It require scheduling protocol to sequence the events. Various useful applications for streaming in internet world are available and their implementation...
Currently, computer technology has been widely used in the teaching of higher mathematics, which lead to a revolutionary change to the traditional teaching theory, method, means and structure and has played a positive to promote the effect of higher mathematics teaching. But, there are several imperfections are occurred in the practical process of computer aided teaching. Therefore, it is necessary...
With increasing interest in the concept of cloud multimedia and the popularization of hand-held devices, users gradually view videos in mobile network streaming mode rather than off-line mode. However, the delays and lags resulted from the instability of a mobile network will greatly degrade streaming quality for users. In cloud multimedia streaming services, when there are multiple optional streaming...
Multimedia MPSoC (Multi-Processor System-on-Chip) has been widely used in today's consumer electronics. As many memory intensive IP (Intellectual Property) cores are integrated into a single chip, the performance of shared memory has been a critical issue. Conventional memory scheduling policies just schedule the existing requests in the queue and waste the potential scheduling space because they...
With the development of the Internet of Thing (IOT) industry, real-time multimedia data transmission services increased significantly. In this paper, we study the key problems of concurrent transmission of real-time multimedia, and we divide the transmission process into stream processing layer, transport control layer and multicast concurrency layer. Particularly in the transport control layer we...
This paper proposes a framework for on-demand video streaming that enables secure and efficient delivery of data towards the end user. Our proposal requires the combined usage of three different technologies. The first one is a recent proposal by Jacobsen et al. [1][2] called Content-Centric Networking (also known as Named Data Networking). It is a network architecture that introduces named data as...
The Media Oriented Systems Transport (MOST) network, the current de-facto standard for in-vehicle multimedia and infotainment, does not provide support for the stream priority and serves bandwidth allocation requests based on their arrival order, irrespective of the stream importance. This work proposes a novel bandwidth allocation approach for multimedia streams on MOST150 networks that introduces...
Due to the recent development of information technologies, streaming delivery on hybrid broadcasting environments has attracted attention. In streaming delivery on hybrid broadcasting environments, clients receive data from communication systems and broadcasting systems. Interruptions occur when the time to receive data is later than the time to play them. Therefore, some methods to reduce interruption...
Vehicle to infrastructure communications can provide mobile users with a series of Internet services, such as video streaming, digital map downloading, database access, online gaming, and even safety services like accident alarm, traffic condition broadcast, etc., through fixed roadside units. However, the dynamics of communication environment and frequent changing topology critically challenge the...
MPEG Dynamic Adaptive Streaming over HTTP (DASH) is a new streaming standard that has been recently ratified as an international standard (IS). In comparison to other streaming systems, e.g., HTTP progressive download, DASH is able to handle varying bandwidth conditions providing smooth streaming. Furthermore, it enables NAT and Firewall traversal, flexible and scalable deployment as well as reduced...
This paper deals with admission control in wireless networks such as WiMAX or LTE. Because of the limited sources, available bandwidth has to be used effectively. In case, where multimedia traffic is considered, each type of service has different requirements for transmission rate and delay. The frequency band has to be divided between several service streams. In this paper, five basic types of service...
