Abstract

In this paper, we present an open source simulation model for the ns-3 simulator that allows the simulation of LTE handover scenarios, to support the design and evaluation of handover decision algorithms. In addition to the features supported by other publicly available open source LTE simulators, such as mobility, propagation, channel, PHY and MAC modeling, our model provides additional features such as the modeling of the RRC protocol, the MAC random access procedure, and the X2, S1 and S11 interfaces. On top of these features, the LTE handover procedure is modeled, following closely the 3GPP specifications. We present in detail the characteristics of each component of the simulation model, highlighting the modeling assumptions that were made in each case.
