| Abstract | ||||
| Nowadays, 5G and beyond mobile communication networks are deployed to accommodate higher dense traffic and different categories of applications. In 5G networks, the deployment of femtocells has increased, since femtocells are regarded as one of the main pillars for boosting network capacity and offering network users (UEs) high quality of service (QoS). Combining many different access nodes creates a heterogeneous network. But in a macro-femto heterogeneous network, specifically in areas of low signal power, macro-users (MUEs) like to access the closest femtocell. However, these accesses will have a negative impact on the serving femto-users (FUEs) because they will affect their demand for resources. Therefore, in our proposal, a femtocell access mode detection scheme (FAM-D) is proposed to find out the proper femtocell access mode (FAM) that will manage the distribution of resources between MUEs and FUEs that are inside the femtocell. After that, we select the proper bandwidth (BW) based on the FAM detection to achieve the resource demands of FUEs and MUEs. Presented numerical results show that the FAM-D is tested over various network densities. In each case, the FAM-D will detect the proper FAM to ensure high QoS for FUs while assisting MUEs who are in need of services without hurting FUEs' needs. After that, we select the proper bandwidth, which will minimize BW utilization. Finally, the number of users prohibited from service can be decreased from 10 UEs to 1 UE using our proposed model. | ||||
