Abstract
Traditionally, rendering and display of 3D graphics require powerful workstations with specialized 3D graphics adapters. However, with significant improvements achieved in both wireless technologies and computational capabilities of mobile devices, it is now possible to exchange and render 3D graphics over wireless networks on mobile devices such as PDA and Laptop. In this paper, we consider a typical scenario where mobile users with different display resolutions and rendering capabilities request the same 3D object in an infrastructure based IEEE 802.11 wireless LAN. We propose to enable packet overhearing and design a feedback based unicast scheduling according to users’ experienced signal strength and delay requirements to handle user mobility. Extensive simulation results show that the proposed schemes in combination can efficiently achieve the dual objectives of maintaining low transmission delays and small distortion.
