Resource allocation in hybrid access control femtocell network targeting inter-cell interference reduction

Inter-cell interference is the most challenging issue in femtocell deployment within the coverage of Macro base station (MBS). In this paper, we have explored the role of femtocell in LTE network and proposed a Dynamic Resource allocation management algorithm (DRAMA) for hybrid access control in spectrum shared OFDMA network to optimize the interference and increase the quality of service (QoS). The user gets the privilege to assign the femtocell service level ensuring a minimum level of QoS. A simulation setting is developed to study the performance of DRAMA in hybrid access control femtocell network and compared it to closed and open access control.
