Road networks are the most important facility to the public transportation in modern cities. Governments around the world allocate large amounts of budgets for the pavement maintenance every year. In this paper, we proposed a crowdsourcing solution to categorize road anomalies into safety related anomalies such as speed bumps and rumble strips, and dangerous anomalies such as bumps and potholes. The...
RFID is a non-contact technology using radio frequencies to achieve automatic and unique identification. It has been widely applied in various areas, such as access management, toll collection, and contact less payment. However, because the information transmission medium between readers and tags is radio frequency, it is easy for attackers to eavesdrop on or tamper with data. Hence, creating a secure...
Nowadays, the majority share of the Internet traffic is contributed by video streaming services. Due to the growth of Internet bandwidth, it is possible to provide HD live streaming services on the Internet which will be a trend in the near future. As the population of the users of HD live streaming services increases, the bandwidth will become a problem again. Centralized-based systems are not suitable...
In the past, although mobile devices were equipped with multiple radio interfaces, for the sake of power saving, only one was activated for data transmission. The idea of concurrent transmission via multiple radio interfaces has not been seriously studied. However, nowadays, power consumption no longer is a problem in many application scenarios, e.g. VANETs. In this work, we investigate the performance...
The success of P2P file sharing systems inspired the development of P2P streaming systems for delivering online multimedia service in the last few years. The capacity of P2P streaming systems, i.e., how many peers can be concurrently serviced by the system, depends on system configurations including network bandwidth, overlay network formation, QoS constraints, membership management, peer selection,...
Thanks to the growing of the wireless networks, the video streaming application becomes a ubiquitous joyful service. In wireless communication networks, the service traffic spans across the wired and wireless domains. Hence, the service of quality (QoS) control becomes complicated. Generally, the QoS is manipulated by the receiving feedback from the mobile user equipments (UEs) to the streaming server...
