The vision of Self-Organizing Networks (SON) has been drawing considerable attention as a major axis for the development of future networks. As an essential functionality in SON, cell outage detection is developed to autonomously detect macrocells or femtocells that are inoperative and unable to provide service. However, due to the two-tier macro femto network architecture and the small coverage nature of femtocells, it is challenging to enable outage detection functionality in femtocell networks. Self-healing functionality in femtocell aims to resolve the loss of coverage or capacity induced by cell outage to the extent possible in the femtocell networks. Existing systems uses local cooperation architecture which seeks solutions with the need for local collaboration among femtocells. Specifically, an outage is detected based on the measurements of surrounding femtocells.

Abstract
The vision of Self-Organizing Networks (SON) has been drawing considerable attention as a major axis for the development of future networks. As an essential functionality in SON, cell outage detection is developed to autonomously detect macrocells or femtocells that are inoperative and unable to provide service. However, due to the two-tier macro femto network architecture and the small coverage nature of femtocells, it is challenging to enable outage detection functionality in femtocell networks. Self-healing functionality in femtocell aims to resolve the loss of coverage or capacity induced by cell outage to the extent possible in the femtocell networks. Existing systems uses local cooperation architecture which seeks solutions with the need for local collaboration among femtocells. Specifically, an outage is detected based on the measurements of surrounding femtocells. Based on these local measurements, a proper set of neighbor femto APs tune their parameters to compensate for the outage. The outage occurs due improper arrangements of femtocell network. Proper placing of the femtocell access points reduces the outage problems. The signal strength, threshold and various parameters are calculated for different configurations and for different modulation technique using a simulation mechanism. The analysis of the same is done .from this analysis proper configuration of the femtocell network is obtained.
