A QoS based comparative analysis between relay assisted and small eNodeB based two-tier LTE network

The inevitable expansion of modern telecommunication sector is enhancing the interest of establishing scalable architectures as well as planned management of available resources to meet the preferred Quality of Service (QoS) demand. Without using a single base station (abbreviated as eNodeB in 3GPP LTE) Internet Service Providers (ISPs) are eager to implement flexible heterogeneous network (Het-Net) architectures with the aim of providing a cost effective improvement in terms of both coverage and capacity. In this paper, considering New Call Blocking Probability, Handoff Call Dropping Probability, and Bandwidth Utilization as QoS parameters, a comparative analysis has been performed between two leading Het-Nets, namely, Multi-hop relay assisted BWA network and Small eNodeB based two-tier BWA network.
