DIASCOPE: Distributed Adaptation System Using Cooperative Proxies in Ubiquitous Network

With evolving modern technology, and widespread deployment of wireless devices, adaptation research is becoming an important issue for over-come various constraints in wireless networks, and maintaining an acceptable level of service. However, most existing research only focuses on wireless device resource utilization, without consideration of proxy server workload execution. In practice, adaptation jobs dynamically converting media formats, consumes a large amount of resources. In this paper, a novel adaptation system is proposed, by distributing workload through nearby cooperative proxies composed of a hierarchical structure. The proposed system has an intelligent engine, which autonomous creates rules. The system performs adaptation work based on rules. A prototype was implemented to evaluate and partly apply this research in a Healthcare scenario. Hence, the effectiveness of the system is confirmed through results, in which the system offers faster adapted content transmission to the user.
