Wireless video surveillance is an important option suitable when it is difficult to have cable Internet and electricity infrastructure, which is the case, for example, for construction yards or vehicles. We present iCam, an open-source Internet-enabled video surveillance project, in which we use mainly discarded camera phones. The mobile application is written mainly in Python on most phone platforms,...
The technological advancements in wireless communication systems enable mobile users to leverage different radio interfaces (e.g., cellular and WiFi) for concurrent data transmission. However, the existing transmission schemes do not seriously consider the problem of real-time video multicast to a cluster of co-located multihomed mobile devices. Conventionally, each client fetches the video streaming...
Asthma is one of respiratory diseases that its symptom does not appear permanently. There are various situations that can be a stimuli for asthma symptoms. Thus, it is difficult to protect patients from an uncontrollable environment. Since most people in Thailand own smartphone either for their personal usage, such as note, calculator, calendar, or communicate with others via applications. Thus, this...
Multimedia streaming applications are among the most energy hungry applications in smartphones. The energy consumption mostly depends on the delivery techniques and on the power management techniques of wireless interfaces (Wi-Fi and 3G). In order to provide insights on what kind of streaming techniques exist, how they work on different mobile platforms, and what is their impact on the energy consumption...
with the development of science and technology, and the increase of people's living standard, people pay more and more attention to safety problems. The traditional fixed video surveillance can not satisfied with people's kinds of new demand. The 3G network construction are mature and a new generation of smart phones has made the mobile video surveillance based on cell phone as a very important way...
Web 2.0 is evolving and offering services based on the wide popularity of smartphones and the possibility of gathering data ubiquitously from these mobile devices; this new paradigm is often referred to as Web2. In this paper, we hence present and discuss a Web2 application designed to enable users to interact with remote smartphones' cameras to receive a video generated in real time. In essence,...
Services based on new information technology offering audio and video modality are viewed among the most important today. When users change location or device there is a need to keep these media sessions active. The main purpose of this article is to present a lightweight framework that allows session mobility through making profit of the cloud and peer-to-peer paradigms, while at the same time fulfilling...
With recent advance in wireless networks and advent of powerful mobile devices such as smart phones, IPTV services become feasible in mobile platforms. Peer-to- Peer streaming techniques are expected be a promising solution to a large-scale mobile IPTV services by providing low cost and high scalability. On the other hand, the major concern for designing mobile IPTV systems is that mobile devices...
To understand the technical feasibility and user perception of mobile video, we conducted a two-week trial where a student community used mobile phone and Web technologies to share the events of a campus festival. The questions we investigated included the capability of contemporary smart phones to capture and share the events via real time and stored video; the usage patterns that arise within mobile...
This paper targets mobile streaming in which Series 60 smart phones are the stream creators and PC-s are the stream consumers. The aim is to provide experimental data reflecting under which conditions video streaming from smart phones is feasible and whether duplex interactive video between a phone and a PC can be achieved or not. Phones used corporate WiFi and UMTS, PC-s were on the corporate Intranet...
