The main objectives of a Self-Organizing Network (SON) technology are autonomous network deployment, network performance optimization and real-time adaptation to environmental changes. There are three functionalities in SON, such as self-configuration, self-optimization and self-healing. In this paper, the authors focus on the self-healing issue with respect to abrupt network faults. In order to solve this problem, they design a Healing Channel (HC) and propose a Collaborative Resource Allocation (CRA) algorithm. Through intensive simulations, they show that the CRA efficiently supports users in disabled Femtocell Base Stations (FBSs) with the little degradation in system capacity.
