“…Figure 3 demonstrates such a setup. To be able to use it for a streaming emulation in the style of the measurements conducted in [14] a bridging device would need to be added on each side of the network, that interfaces with a real testbed network. The only task of the simulated part is then to alter the network QoS parameters of the link according to its model.…”

TCP-based streaming has garnered much research interest in the past few years. Yet it still remains difficult to evaluate the performance of such streaming approaches in mobile networks. In the past, this could be be partly attributed to the scarce availability of mobile network simulators but this circumstance has changed. Nevertheless, there are many open issues and challenges in video delivery over mobile networks.Inspired by the lack of tools for assessing video streaming QoS and QoE, we provide a streaming framework on top of one of the existing mobile network simulators. The framework is configurable and extensible enough to be able to be employed for many mobile and other network scenarios. The provided scenarios and example playback strategies are put to the test in some initial experiments. In these, a negative impact of mobility on the playback of a streaming video could already be revealed. 27th International Teletraffic Congress978-1-4673-8422-3/15 $31.00

“…Staehle et al[98] present YoMo which can constantly monitor the YouTube application by comforting and detecting the stalling of the video. Ma et al[99] provide an overview of the current mobile content delivery ecosystem and discuss the expanding role of HTTP-based mobile video delivery.Metzger et al[100] study video stream buffering and playback control. They claim that choosing the right buffering model can make a huge difference on the quality of the playback process.…”

Smartphone has become one of the most revolutionary devices in the history of computing. With various kinds of applications, the scope of smartphone has been significantly broadened in the past few years including almost every aspect in our daily life. However, due to the limited on-board resources such as CPU, storage, network bandwidth and battery power, smartphones and the mobile network serving them bring new challenges that have not been encountered in the traditional computing and networking environments. This dissertation focuses on the research areas of improving the network architecture and enhancing the current applications on smartphones. It mainly investigates the areas in the following two directions for three representative categories of mobile services. - In the first direction, the dissertation aims to develop new communication models for smartphone Ad-Hoc networks to achieve efficient communication in the proximity. It is motivated by the fact that smartphone Ad-Hoc networks can help improve the current location-based services and propel new applications. Moreover, the new communication models provide complementary alternatives to the traditional infrastructure-based wireless networks. - In the second direction, the dissertation focuses on improving the other two categories of services, cloud storage services and real-time video streaming services for mobile devices. In the field of cloud storage, we introduce a cloud-assisted approach to provide a set of advanced file operations, such as encryption, decryption and compression, on smartphones. Furthermore, by utilizing the on-board Near Field Communication(NFC) module, we develop an algorithm to securely share the files between mobile devices. For the services of real-time video streaming, we propose approaches that identify a user’s status by analyzing the accelerometer data and then, dynamically adjust the buffer mechanism to save network bandwidth on smartphones.
