Abstract

Summary: Multicast‐Broadcast over Single Frequency Network (MBSFN) technology, as introduced by the Long Term Evolution Advanced group, is expected to be part of the upcoming cellular systems offering resource efficiency to broadcast services. MBSFN transmission is suitable to serve multicast groups searching the same content. In addition, the fast emerging technology of femtocells networks and their hybrid nature can lead to efficient resource sharing between non‐subscribed users when located inside their coverage. The focus of this manuscript is 2‐fold; firstly, we have contacted simulation experiments to compare the MBSFN transmission with the traditional Point‐To‐Point transmission for various femtocell distributions and network topology changes; secondly, a novel multicast transmissions mechanism is proposed from non‐subscribed users who exploit femtocells resources for broadcast services, without limiting user's data requirements. The simulation results lead to a significant system's performance in terms of average throughput, total capacity, and energy consumption. Abstract : Multicast‐Broadcast over Single Frequency Network transmission exploiting hybrid femtocell access guarantees better system performance, increased average throughput, better energy efficiency, and a significant increase in the system capacity as the femtocell density increases in comparison with the Point‐To‐Point transmissions. This can be achieved by choosing the most suitable Modulation and Coding Scheme to serve the users inside the Multicast‐Broadcast over Single Frequency Network area.
