Stability Emphasizing Cross-Layer Optimization of Transmit Power Allocation in Distributed Wireless Networks
Abstract— This paper theoretically analyzes cross-layer optimized design of transmit power allocation in distributed interference-limited wireless networks with asynchronously acting links and stochastic communication channels, whereby the link’s architecture is abstracted into three layers - a physical, a data link and a network layer. We treat the transmit power allocation process as a result of coupled interaction, in which all the three layers try to satisfy their individual requirements on power control, admission control and routing respectively. Using a best-response approach for system modeling and the notion of network’s stability for its cross-layer optimization, we present simple power control and admission control algorithms for convergent iterative allocation of equilibrium transmit powers, which optimally balance the network-wide trade-off between allocated transmit powers and resulting interference. Numerical simulations evaluate the achievable stability of our sc...
