However, its code is not yet available and, for this reason, it cannot adequately serve the research community. At Aopen ALN-328 present, to the best of our knowledge, the only valuable tool is Aopen ALN-328 one developed for the network simulator 3 NS-3 within the LENA project[ 16 ]. Unfortunately, despite it provides standard compliant definition of the LTE network architecture as well as several propagation loss models for indoor scenarios, at the current status it cannot be sufficient in helping researchers during the study of femtocell related issues.

In Aopen ALN-328, it Aopen ALN-328 not implement any handover strategies for HetNet, it does not allow the application of different access policies to the HeNB, it offers only a weak support for the quality of service QoS management[ 17 ] e. In addition, the setup of a realistic simulation scenario is difficult to accomplish, especially for a non-expert NS-3 user.

To bridge this gap, the present study proposes a module that extends the functions of the emerging Aopen ALN-328 source LTE-sim framework[ 18 ], thus allowing also the simulation of scenarios with LTE femtocellsa. It provides a wide range of features and high scalability.


It encompasses scenarios with both macro and femto cells, in multi-cell and multi-user environments, and implements a complete LTE protocol stack along with advanced RRM techniques, such as frequency reuse schemes, packet scheduling, and QoS management. User mobility is also considered and several configurations of mobility patterns and handover mechanisms are considered. We believe that the developed tool represents a good and useful research tool for Aopen ALN-328 several open issues such as: In order to shed some light on the practical utility of the proposed tool, in this article we report some examples about its application. In particular, some reference indoor and urban Aopen ALN-328 are evaluated.

It is worth to note that such an analysis is only intended to demonstrate the general agreement between what is expected from a theoretical point of view and the outcomes of the simulation module we propose. Furthermore, a scalability analysis to measure the computational requirements of the developed tool i. The rest of the article is organized as follows: Section 2. In Section 3.


Section 4. Finally, Section 5. From the network side, the evolved NodeB eNB Aopen ALN-328 the only node of the E-UTRAN and it is in charge of providing network connectivity through the air interface to all user equipments UEs in the cell, according to the classic cellular network paradigm. At the physical layer, the radio interface supports both frequency and time divisions duplexing. Channel access, instead, is based on orthogonal frequency division multiple access OFDMAwhich provides high flexibility in terms of scheduling and interference management[ 3 ]. In the time domain, they are distributed every Aopen ALN-328 time interval TTIeach one lasting 1 ms.

Furthermore, each TTI is composed by two time slots of 0.

In the Aopen ALN-328 domain, instead, the whole bandwidth is divided into kHz sub-channels, corresponding to 12 consecutive and equally spaced sub-carriers. Note that, due to the fixed sub-channel size, the number of sub-channels varies accordingly to different system bandwidth configurations e. In[ 20 ], the 3GPP introduced a new low-power and small-range radio based station, i.

The very limited geographical area it covers is called femtocell Figure 1. Figure 1 Network architecture macro and femto cells.
