Adaptive information content management and buffer caching design for robust real-time streaming over IP network

Abstract

This paper presents robust adaptive information content system design using contiguous buffering scheme buffers for high data rate real-time applications like ehealth, telemedicine and 3-D video using IP network. The design improves the resiliency of the realtime systems under adverse network conditions like congestion and/or temporary loss of connectivity and ensures that critical application data is not lost. The proposed adaptive information content management design for a high data rate real-time application shows how information content can be adaptively managed using contiguous sender buffer to reduce the data transfer rate when underlying network capacity changes over a time period, improving the survivability interval of the system. There is a tradeoff between loss of features, data rate reduction, criticality of the lost information and survivability time of the systems.

Architecture for adaptive remote patient monitoring

“…• The proposed AICM method was applied to the bed occupancy data collected in an earlier clinical trial to demonstrate how improved survivability for the RPM system can be realized. The proposed AICM method and buffering scheme presented in Chapter 5, 6 and 7 has been submitted for review in [4]…”

“…Fig. 7.13 display the time to live of the system for each information content reduction scheme [4]. The accuracy and sensitivity of the estimation and detection algorithms are dependent on the quality of the extracted movement and breathing effort signals, which are in turn dependent on the information content of the received sensor data.…”

“…The case study demonstrates how information content can be reduced to achieve higher survivability interval under adverse network condition and the impact of reduced information content on system performance. The results have been submitted for review in [4].…”
