A Consensus-Based Coverage Algorithm For Self-Organizing Femtocell Networks

In this letter, a consensus-based distributed coverage algorithm is proposed for self organization in two-tier femtocell networks. One key feature of the algorithm is that it achieves fairness among users in terms of signal quality without relying on any predefined target values. The stability of the proposed algorithm is investigated using quadratic Lyapunov functions, which also allow us to analyze its convergence rate properties. The simulation results are not only in agreement with the theoretical analysis, but also demonstrate significant improvement in terms of overall network performance.
