“…A large body of work have proposed prioritized approaches for a differentiated transmission service among contents of various priorities. For example in [18], and [23] the authors adopted prioritization techniques towards the study of efficiently transmitting 3D contents to resource-limited devices given the importance of various objects in the gaming context. The authors in [24] applied the concept of prioritization on a multi-user teleconference room equipped with a static camera capturing the whole room.…”

Abstract-The ultimate objective of medical cyber-physical systems is to enhance the safety and effectiveness of patient care. To ensure safe and effective care during emergency patient transfer from rural areas to center tertiary hospitals, reliable and real-time communication is essential. Unfortunately, real-time monitoring of patients involves transmission of various clinical multimedia data including videos, medical images, and vital signs, which requires use of mobile network with high-fidelity communication bandwidth. However, the wireless networks along the roads in rural areas range from 4G to 2G to low speed satellite links, which poses a significant challenge to transmit critical patient information.In this paper, we present a bandwidth-compliant criticalityaware system for transmission of massive clinical multimedia data adaptive to varying bandwidths during patient transport. Model-based clinical automata are used to determine the criticality of clinical multimedia data. We borrow concepts from DASH, and propose physiology-aware adaptation techniques to transmit more critical clinical data with higher fidelity in response to changes in disease, clinical states, and bandwidth condition. In collaboration with Carle's ambulance service center, we develop a bandwidth profiler, and use it as proof of concept to support our experiments. Our preliminary evaluation results show that our solutions ensure that most critical patient's clinical data are communicated with higher fidelity.

“…Our other experimental results show similar trends. Figure 3 shows the experimental results for the total quality achieved using our three adaptation algorithms.We used two different triples (p0, p1, p2) of first-level and second-level priorities relative to p0, (1,2,2) and (1,3,3), to differentiate the priorities of streams in different classes. We set p0 = 1 to normalize the priorities.…”

“…Hosseini et al [4,3] adopted priority-based approaches towards the study of efficiently transmitting, rendering, and displaying bulky 3D gaming information to power-limited devices given the importance of different 3D objects in the gaming context. Also in the context of telepresense, DeVincenzi et al [2], applied the concept on an intelligent teleconference room accommodating multiple users, which is equipped with a fixed camera capturing the whole room.…”

3D tele-immersion improves the state of collaboration among geographically distributed participants. Unlike the traditional 2D videos, a 3D tele-immersive system employs multiple 3D cameras based in each physical site to cover a much larger field of view, generating a very large amount of stream data. One of the major challenges is how to efficiently transmit these bulky 3D streaming data to bandwidth-constrained sites. In this paper, we propose an adaptive Human Visual System (HVS) -aware bandwidth management framework for efficient delivery of multiple streams produced from distributed 3D tele-immersive sites to a receiver site with limited bandwidth budget. Our novel adaptation framework exploits the semantics link of HVS with multiple 3D streams in the 3D tele-immersive environment. Our evaluation results show that the proposed HVS-aware adaptation improves the total quality per unit of bandwidth used to deliver streams in 3D tele-immersive systems.

“…Game objects adaptation approaches include adapting their elements such as textures and lighting effects that are more bandwidth and rendering computation expensive, by taking into consideration the object importance and bandwidth restrictions [19]. On the same idea multimedia stream adaptation can be done for example by encoding different areas of a frame corresponding to game elements at different quality [20].…”

Within the growing of the gaming industry and mobile technologies, cloud-based video games streaming to mobile devices gains popularity fast. However, several issues and challenges such as user responsiveness, video quality, service quality, operating cost and energy consumption have to be addressed. Previous research studies did not thoroughly investigate the energy consumption of mobile devices used for cloud gaming. This paper focuses on how mobile device energy consumption is impacted by video game content characteristics, transmission protocol and wireless network type. The results show that game content characteristics impact energy consumption (i.e., up to 47% between games at maximum brightness for OLED screens), UDP is more energy efficient than TCP (i.e., up to 13.6%), while WiFi is more energy efficient than 3G (i.e., up to 40%). The outcome of this study can provide beneficial input for adaptive energy efficient cloud-based video games streaming mechanisms.
