The next generation of networks (NGNs) will involve interconnection between heterogeneous individual networks such as WPAN, WLAN, WMAN, Cellular, each employing various technologies such as Bluetooth, UWB, WiFi, WiMAX, UMTS, etc. Even though they adopt the IP as common infrastructure-related protocol and provide virtually always-connected network, the heterogeneity of connectivity raise various challenges in terms of performance and cost effectiveness. Furthermore, the amount of information available to share and exchange in this situation makes user handling it manually almost impossible and automated solutions are required.
In this context Smart PIN was proposed as a performance and cost-oriented context-aware personal information network which enables efficient user access to information distributed across different networks employing various access technologies based on user interest. Using autonomous data replication based on user utility, Smart PIN provides performance-oriented information exchange to its users. The information dealt with by Smart PIN includes both non-real time and realtime data.
The goal of this project is to compare existing distributed video applications [1, 2] such as multiple-description coding (MDC), Layered Coding (LC) and other adaptive solutions in a heterogeneous network environment in terms of performance in an information overload situation. Network simulation will be used for evaluating the performance of each approach.
Relevance of the Project to "Technologies for Social Connectedness"
This project will look at how adaptation of information – especially realtime - will improve the performance of information distribution in a heterogeneous network environment and will enable better user connectivity anywhere anytime and from any device.
Demonstratable Outcome
The outcome of the project will be a simulation model.
