Chance-Constrained Optimization of Reliable Fixed Broadband Wireless Networks

A Chance-Constrained Model & Cutting Planes for Fixed Broadband Wireless Networks

In this paper, we propose a chance-constrained mathematical program for fixed broadband wireless networks under unreliable channel conditions. The model is reformulated as integer linear program and valid inequalities are derived for the corresponding polytope. Computational results show that by an exact separation approach the optimality gap is closed by 42 % on average.

Energy Saving in Fixed Wireless Broadband Networks

In this paper, we present a mathematical formulation for saving energy in fixed broadband wireless networks by selectively turning off idle communication devices in low-demand scenarios. This problem relies on a fixed-charge capacitated network design (FCCND), which is very hard to optimize. We then propose heuristic algorithms to produce feasible solutions in a short time.

Channel Allocation for Broadband Fixed Wireless Access Networks

Fixed Cell Assignment for Forward Link in Broadband Wireless Networks

This paper proposes a new allocation method, called the Fixed Cell Assignment, which provides wireless Internet access by employing time division multiple access transmission for the forward link in broadband (10 Mbit/s) wireless networks. The system is configured with directional base station antennas and omnidirectional mobile antennas, with each cell divided into six sectors, and sectors num...
