Region-And Action-Aware Virtual World Clients

Free registration required

Executive Summary

The authors propose region- and action-aware virtual world clients. To develop such clients, they present a parameterized network traffic model, based on a large collection of Second Life traces gathered by them. Their methodology is also applicable to virtual worlds other than Second Life. With the traffic model, various optimization criteria can be adopted, including visual quality, response time, and energy consumption. They use energy consumption as the show case, and demonstrate via trace-driven simulations that, compared to two existing schemes, a mobile client can save up to 36% and 41% communication energy by selectively turning on its Wi-Fi network interface.
