Random access improvement for M2M communication in LTE-A using femtocell

Abstract

<p><span>When an area is highly populated with Machine-to-Machine devices and all these devices attempt to access the Random Access Network Simultaneously, congestion is created on the network which degrades the performance of the network to other users. In this paper, the researchers are seeking to improve network accessibility by deploying more Femtocell into the network. They engaged the use of Extended Access Barring to restrict the M2M devices from accessing the network via macrocell eNB when a minimum load threshold is attained, thereby preventing the macrocell eNB from being congested. Deploying these Femtocells underneath the macrocell eNB comes with the issue of Inter-Cell Interference which nullifies any gains made by this deployment. The researchers employed Fractional Frequency Reuse and Complete Frequency Reuse schemes to mitigate the negative effects of ICI to augment the throughput of the network, improve the system capacity and enhanced the user experience within the network.</span></p>

Pedestrian mobility management for heterogeneous networks

“…Thus, by minimizing path loss, better signaling can be delivered to the receiver [27]. The indoor regions are characterized by the deployment of FBS', their role is to bring a better QoS and quality of experience (QoE) for users [11], [17], [18], [28], [29]. As a result, the QoS degrades to multiple environmental factors, such as floors and walls.…”
