Video traffic has witnessed exponential growth in recent years. As the cost optimization space of Content Delivery Network (CDN) has reached a plateau, content providers are expanding their network infrastructure to accommodate this surge. To address the ...

Motivated by applications in web caches and content delivery in peer-to-peer networks, we consider the non-metric data placement problem and develop distributed algorithms for computing or approximating its optimal solutions. In this problem, the goal is ...

Internet content providers often deliver content through bandwidth bottlenecks that are out of their control. Thus, despite often having massively over-provisioned upstream servers, the content providers still cannot control the end-to-end user ...

Conventional wisdom claims that in order to improve viewer engagement, the cloud-edge providers should serve the viewers with the nearest edge nodes, however, we show that doing this for crowdsourced live streaming (CLS) services can introduce ...

The majority of Web content is delivered by only a few companies that provide Content Delivery Infrastructuress (CDIss) such as Content Delivery Networkss (CDNss) and cloud hosts. Due to increasing concerns about trends of centralization, empirical ...

The demand for content such as multimedia services with stringent latency requirements has proliferated significantly, posing heavy backhaul congestion in mobile networks. The integration of Multi-access Edge Computing (MEC) and 5G network is an ...

Video streaming is the most used service in mobile networks and its usage will continue growing in the upcoming years. Due to this increase, content delivery should be improved as a key aspect of video streaming service, supporting higher bandwidth ...

Intelligent Transportation Systems (ITS) are gaining substantial attention owing to the great benefits offered to the vehicle users. In ITS paradigm, content data is normally obtained from road side units (RSUs). However, in some scenarios, terrestrial ...

Online services all seek to provide their customers with the best Quality of Experience (QoE) possible. Milliseconds of delay can cause users to abandon a cat video or move onto a different shopping site, which translates into lost revenue. Thus, ...

Anycast has been increasingly deployed for content delivery networks to map clients to their nearby replicas, which relies on the underlying routing. However, the simplicity of operation comes at cost of less precise client-mapping control. Although many ...

Efficient content delivery in vehicular networks will play a fundamental role in empowering envisioned vehicular and smart transportation applications. However, the peculiar characteristics of vehicular networks (e.g., high mobility, dynamic network ...

Various trends are reshaping Internet video delivery: exponential growth in video traffic, rising expectations of high video quality of experience (QoE), and the proliferation of varied content delivery network (CDN) deployments (e.g., cloud computing-...

Network slicing has been considered as one of the key technologies in the next generation mobile network (fifth generation – 5G), which can create virtual network and provide customised services on demand. Most of the current work on network slicing ...

The aim of this article is to provide an understanding of social networks as a useful addition to the standard toolbox of techniques used by system designers. To this end, we give examples of how data about social links have been collected and used in ...

There is increasing interest in developing technologies that attempt to deliver content based on user's location. Although many applications can be used for this task, there are still obvious limitations that require improvement. In this paper, location-...

With the world population becoming increasingly urban and the multiplication of mega cities, urban leaders have responded with plans calling for so called smart cities relying on instantaneous access to information using mobile devices for an ...

With the explosive increase of video traffic and content sharing applications among mobile devices such as smart phones and mobile tablets, device-to-device (D2D) technique has become attractive in the application to content delivery since it can ...

Streaming video has received a lot of attention from industry and academia. In this work, we study the characteristics and challenges associated with large-scale live video delivery. Using logs from a commercial Content Delivery Network (CDN), we study ...

A significant number of promising applications for vehicular ad hoc networks (VANETs) are becoming a reality. Most of these applications require a variety of heterogenous content to be delivered to vehicles and to their on-board users. However, the task ...

There has been increasing interest in designing and developing highly scalable infrastructures to support the efficient distribution of content. This has led to the recent development of content-oriented network architectures that rely on on-demand ...
