Cross-Layer Optimization for Wireless Networks With Deterministic Channel Models
Cross-layer optimization is a key step in wireless network design that coordinates the resources allocated to different layers in order to achieve globally optimal network performance. Existing works on cross-layer optimization for wireless networks often adopt simplistic physical-layer models for wireless channels, such as treating interference as noise or interference avoidance. This crude modeling of physical layer often leads to inefficient utilization of resources. In this paper, the authors adopt a deterministic channel model proposed a simple abstraction of the physical layer that effectively captures the effect of channel strength, broadcast and superposition in wireless channels.
