“…Aioffi et al [20] proposed a mobile dynamic content distribution network model that aims to reduce the total traffic in enterprise networks. To achieve this, their model takes into account the variation of throughput demands in order to decide whether to remove or keep the replicas in the network.…”

Abstract-Cellular networks are currently facing the challenges of mobile data explosion. High-end mobile phones and laptops double their mobile data traffic every year and this trend is expected to continue given the rapid development of mobile social applications. It is imperative that novel architectures be developed to handle such voluminous mobile data. In this paper, we propose and evaluate an integrated architecture exploiting the opportunistic networking paradigm to migrate data traffic from cellular networks to metropolitan WiFi access points (APs). To quantify the benefits of deploying such an architecture, we consider the case of bulk file transfer and video streaming over 3G networks and simulate data delivery using real mobility data set of 500 taxis in an urban area. We are the first to quantitatively evaluate the gains of citywide WiFi offloading using large scale real traces. Our results give the numbers of APs needed for different requirements of quality of service for data delivery in large metropolitan area. We show that even with a sparse WiFi network the delivery performance can be significantly improved. This effort serves as an important feasibility study and provides guidelines for operators to evaluate the possibility and cost of this solution.

“…A model for mobile dynamic CDN should be designed to allow the access of accurate and up-to-date information and enterprise applications. Such a mobile dynamic CDN model for enterprise networks and related content management policies are presented by Aioffi et al [12]. Example of a commercial mobile CDN provider is Ortiva Wireless [8], which delivers audio, video, and multimedia content to mobile users.…”

IntroductionWith the recent development of technologies in wireless access and mobile devices, the mobile network has become a key component of today's Internet vision [1,46]. Current mobile networks, which are being deployed worldwide, enable mobility features to new applications and also extend existing wired Web applications to mobile terminals. The mobile wireless network offers a rich assortment of dynamic and interactive services, such as GPS navigation information, mobile TV, vehicular traffic information, and location-oriented services. The provision of such services requires techniques to disseminate data as efficiently as possible in order to minimize the total network traffic and to improve the mean response time to mobile users.In the wired Web, network performance can be substantially enhanced by using additional bandwidth, which is often available at low cost. However, this approach is impractical for mobile wireless network infrastructures. Most of these networks have fixed spectrum and achievable data rate is fundamentally limited by interference [46]. This problem is likely to get more serious when more mobile users start using bandwidth-intensive services such as streaming media. In this context, caching and prefetching might be a solution. Specifically, these approaches have been extensively used in the wired Web to optimize the amount of bandwidth consumption by shifting the traffic away from overloaded content providers and closer to the content customers [43]. Although these methods offer several benefits (i.e. conservation of network resources and reduced latency), the dissemination of dynamic content and resource-hungry applications (e.g. multimedia applications) remain a challenge. Content Delivery Networks (CDNs) promise to address these challenges by moving the content to the "edge" of the Internet, and thus closer to the end-user [45]. An introduction to CDNs can be found in the first chapters of this book. Although there has been much work on wired CDNs [27,32,40], content dissemination on mobile environments has received little attention so far [1,49]. This is due to the limited Internet access capabilities of most mobile terminals in the recent past. However, this situation seems to be changing with the advent of innovative cellular (e.g. 3G) and wireless (e.g. WiFi) services which allow mobile terminals to access Internet and other data services at speeds comparable to traditional wired access [46]. Previous research [6,48] shows that cooperative caching in mobile environment improves the network performance and information dissemination. In this context, we believe that the infrastructure of CDNs may provide a scalable and cost-effective mechanism for accelerating the information dissemination in the mobile wireless environment [45]. However, the mobile wireless network infrastructure represents a fundamentally different information medium from the traditional Web in terms of access devices used, content availability, bandwidth, and cost to the end-user. Thus, the typical CDNs can...
