An Interference-Aware Virtual Clustering Paradigm for Resource Management in Cognitive Femtocell Networks
Source: Open University
Femtocells represent a promising alternative solution for high quality wireless access in indoor scenarios where conventional cellular system coverage can be poor. Femtocell Access Points (FAP) are normally randomly deployed by the end user, so only post deployment network planning is possible. Furthermore, this uncoordinated deployment creates the potential for severe interference to co-located femtocells, especially in dense deployments. This paper presents a new femtocell network architecture using a Generalized Virtual Cluster Femtocell (GVCF) paradigm, which groups together FAP, which are allocated to the same Femtocell GateWay (FGW), into logical clusters.
