Traditionally, enterprise application integration (EAI) processes structured data. Recent trends such as social and multimedia computing led to an increase in unstructured multimedia data like images and video streams that have to be processed by EAI. This poses challenges to EAI with respect to variety, velocity, and volume of the processed data. Furthermore, multimedia data has more semantic qualities...
One of the goals of next generation home entertainment is to provide realistic media contents to the users. Realistic media contents are media with multiple sensorial effects (mulsemedia) aimed at increasing user's experience through the five sense representation (i.e., taste, sight, touch, smell, and hearing). In this research area, a key issue is the interconnection between the various output devices...
Ground personnel at the tactical edge often lack data and analytics that would increase their effectiveness. To address this problem, this work investigates methods to deploy cloud computing capabilities in tactical environments. Our approach is to identify representative applications and to design a system that spans the software/hardware stack to support such applications while optimizing the use...
Access control (AC) is critical for preventing sensitive information from unauthorized access. Various AC systems have been proposed and enforced in different types of information systems (e.g., bank and military). However, existing AC systems cannot thoroughly address the challenges in emerging distributed processing systems (DPS), such as Big Data (BD) and Cloud, due to their dynamic and complex...
Live media streaming applications are increasingly popular, with services such as Twitch.tv and YouNow being used by millions of people. Deploying such services on the cloud can be very expensive, as the cost is proportional to the amount of data transferred to the users. However, adopting a much less costly peer-to-peer (P2P) solution may reduce the overall quality-of-service (QoS) experienced by...
Streaming Media is a multimedia that is presented to an end user which is constantly received by while being delivered by a provider. Amazon Web Service (AWS) is a collection of remote computing services (also called web services) that together make up a Cloud computing platform, offered over the Internet by Amazon.com. The most central and well-known of these services are Amazon EC2 and Amazon S3...
Recently, Vehicular Ad-hoc Network (VANET) has been drawing lots of attentions from many researchers. It is considered as an important future network for Intelligent Transportation Systems (ITS). Meanwhile, the cloud network has been gradually accepted by more and more customers as a flexible storage and computing facility. In this paper, we propose a novel communication system to integrate vehicular...
Wireless video applications for Industrial Internet Of Things (IoT) are expanding into a multitude of new services. In the example of cloud processing for visual object detection, a camera is connected to the cloud via a local server and a data network, allowing the processing load to be handled in a distributed manner. This service model heavy taxes the data network with potentially unneeded traffic,...
Triggered by several head-mounted display (HMD) devices that have come to the market recently, such as Oculus Rift, HTC Vive, and Samsung Gear VR, significant interest has developed in virtual reality (VR) systems, experiences and applications. However, the current HMD devices are still very heavy and large, negatively affecting user experience. Moreover, current VR approaches perform rendering locally...
Smart-home is becoming increasingly popular in recent years, and it introduces a new content retrieval paradigm - delay-insensitive downloading. In this new paradigm, users do not require the content retrieval task to finish as soon as possible, but only set a deadline for it. We study the role of this paradigm in the traffic engineering of a chunk-based cloud storage service. We propose that it could...
As cloud computing industry adoption rate is increasing, service cost management and optimization are becoming one of the most important issues from the perspective of cloud users. This paper is looking into possibility of using information about application type and its resource usage profile in the process of identifying optimized service placement in cloud environments. Such placement should result...
With the popularity of many massive online courses (MOOCs) and relevant platforms such as the Coursera, edX and Udemy, open learning and education will obviously become a very influential and significant sector in education all over the world, especially for developing countries like China and India with large population sizes and huge demands for tertiary education to develop the knowledge-based...
Network "softwarization" is gaining increasing popularity to achieve dynamicity and flexibility. Cloud computing, together with the new paradigms of SDN and NFV are supporting this evolution. However, the need to move services closer to users to guarantee low latency in the service fruition on one hand, and the trend to support personalization of services on the other hand, are stimulating...
The paper proposes provisioning methods for VoD service providers offering adaptive video streaming in a cloud environment. Our methods minimize costs paid by VoD provider thanks to rational use of on the fly video transcoding service which eliminates storage cost of rarely requested video profiles. In the paper, we formulate provisioning problem, propose optimization and heuristic methods that determine...
New generations of cloud applications are increasingly complex and pose lower latency requirements. e la er is forcing the industry to reduce network latency by adding computation nodes near the edge of the network, also known as Fog Computing. To utilize the Fog nodes efficiently, the dynamic placement and migration of application components must be supported. To this end, a Fog- aware application...
Availability is an important non-functional requirement for carrier grade services. Cloud computing is gaining in popularity but availability remains one of its main challenges in order to convince carrier grade service providers to migrate to the cloud. Several solutions, including Pacemaker/Corosync, have been proposed for managing the availability of cloud systems. On the other hand, OpenSAF, an...
Abstract-With the rapid development of streaming media, communications between Device-to-Device is becoming a magnetic solution to improve the performance of cellular network.Although numerous papers have been published in the past, most of them just focus on novel description but ignore the classical theory to be innovated. In this paper, inspired by BitTorrent protocol, we propose a dynamic d2d...
A cloud-based video course recording model is proposed in this paper to record and deal with classroom information in the learning management system (LMS). In the developed model, a new foundations key frame description technology (FKD) has been developed. A cloud-based key frame description library (CKDL) has been improved to raise the speed of retrieval. At the same time, a novel approach has been...
This paper proposes a batch-based method to effectively relax the flash crowd in P2P live streaming systems with the aid of the cloud. The role of the cloud is twofolds. The first one is to determine the concrete overlay structure of batches consisting of nodes waiting in the request queue which is restricted to be a multiple-spanning-tree. With this approach we could maximize the resource utilization...
