Evaluation of X2-Handover Performance Based on RSRP Measurement with Friis Path Loss Using Network Simulator version 3 (NS-3)

Long term evolution (LTE) is the next generation after UMTS system which developed by 3GPP release 8. LTE as the fourth generation provides a high transmission speed and high mobility to the user. In this paper we concern about the mobility performance. In order to see the mobility performance, handover scenario is chosen. Handover scenario is based on lena-x2-handover-measure script which provided in network simulator (ns-3). The ns-3 is used to simulate the x2-handover using lena-x2-handover-measure. Lena-x2-handover-measure instantiates one UE attached to serving eNodeB and moves toward neighbor eNodeB. The focus is on the impact of A2 and A4 event based on measurement report known as reference signal receive power (RSRP) and reference signal receive quality (RSRQ) on x2-handover performance in different parameters such as velocity, distance and eNodeB transmitted power. Receive power is calculated using Friis path loss equation and later it will be compared with the simulation result.
