The addition of these base stations extends the offered system capacity and coverage area of the network. This two network parameters nowadays becomes rather important to provide Quality of Service (QoS) for data-hungry applications. Femto base stations (FBS) are deployed randomly to extend the coverage of conventional base stations. Since the femtocells are operating here in open access mode, so that the handover probability parameter becomes important concern.

The benefit of using femtocells is the capacity and coverage extension capability. To fulfill strict Quality of Service (QoS) requirements in next generation mobile networks such as LTE (Long Term Evolution) or LTE-Advanced, capacity and coverage enhancing becomes rather important. On the other hand, adding small cells like femtocells next to macrocell modifies the interference pattern of the current region. Therefore the number of small cells in a given area should be limited. In this paper we provide an analytic framework to calculate the outage probability for a macrocell user in OFDM based femtocell networks when the deployed femto base stations are composing an independent Poisson cluster process (PCP) such as Thomas cluster process. Cluster based femtocell modeling offers accurate network planning for mobile operators. In this cluster based realization we give an interference characterization and consider the outage probability for a randomly deployed user when communication channel is infected with Rayleigh fading.}, year = {2015}, eissn = {1530-8677}, pages = {2179-2190}, orcid-numbers = {Jeney, Gábor/0000-0002-3029-165X} } @article{MTMT:2818731, title = {Loss-minimal Algorithmic Trading Based on Levy Processes}, url = {https://m2.mtmt.hu/api/publication/2818731}, author = {Farhad, Kia and Jeney, Gábor and Levendovszky, János}, journal-iso = {TEM JOURNAL}, journal = {TEM JOURNAL: TECHNOLOGY EDUCATION MANAGEMENT INFORMATICS}, volume = {3}, unique-id = {2818731}, issn = {2217-8309}, year = {2014}, eissn = {2217-8333}, pages = {210-215}, orcid-numbers = {Jeney, Gábor/0000-0002-3029-165X; Levendovszky, János/0000-0003-1406-442X} } @article{MTMT:2818665, title = {Minimum Probability of Loss Trading Strategy for Mean Reverting Portfolios}, url = {https://m2.mtmt.hu/api/publication/2818665}, author = {Farhad, Kia and Jeney, Gábor and Levendovszky, János}, journal-iso = {INT INTERDISC J SCI RES}, journal = {INTERNATIONAL INTERDISCIPLINARY JOURNAL OF SCIENTIFIC RESEARCH}, volume = {1}, unique-id = {2818665}, issn = {2200-9833}, year = {2014}, pages = {53-63}, orcid-numbers = {Jeney, Gábor/0000-0002-3029-165X; Levendovszky, János/0000-0003-1406-442X} } @article{MTMT:2796906, title = {Analyzing LTE Small Cell Interference Distribution via Fading Factorial Moments}, url = {https://m2.mtmt.hu/api/publication/2796906}, author = {Jakó, Zoltán and Jeney, Gábor}, doi = {10.5176/2251-3388_2.2.49}, journal-iso = {GSTF J MATH STAT OPER RES (JMSOR)}, journal = {GSTF JOURNAL OF MATHEMATICS, STATISTICS AND OPERATIONS RESEARCH (JMSOR)}, volume = {2}, unique-id = {2796906}, issn = {2251-3388}, year = {2014}, eissn = {2251-3396}, pages = {36-40}, orcid-numbers = {Jeney, Gábor/0000-0002-3029-165X} } @article{MTMT:2748011, title = {A Study on the Performance of an Advanced Framework for Prediction-based NEMO Handovers in Multihomed Scenarios}, url = {https://m2.mtmt.hu/api/publication/2748011}, author = {Bokor, László and Jeney, Gábor and József, Kovács}, journal-iso = {INFOCOMM J}, journal = {INFOCOMMUNICATIONS JOURNAL}, volume = {6}, unique-id = {2748011}, issn = {2061-2079}, abstract = {In this paper we provide an extensive performance evaluation of an already introduced advanced handover management solution which aimed at providing ubiquitous IPv6 connection and seamless Internet access for network mobility (NEMO) scenarios. The novel solution makes use of geographic location information and previous records of access network parameters. The method exploits the benefits of multihomed mobility configurations by introducing a special handover execution protocol entirely based on flow bindings. Using actual location information and previously recorded context data, the system is able to predict handovers and proactively prepare itself for the appearance of access networks. We studied the performance of our proposal by implementing the framework and handover execution scheme in a real-life 3G/Wi Fi multi-access testbed environment, and showed that handover latency is almost totally eliminated. As our solution strongly relies on the prediction accuracy, we have also developed a probabilistic system model and evaluated of the probability of wrong positioning on the prediction raster.}, year = {2014}, eissn = {2061-2125}, pages = {16-27}, orcid-numbers = {Jeney, Gábor/0000-0002-3029-165X} } @inproceedings{MTMT:2731962, title = {Coverage Analysis of Matérn Cluster Based LTE Small Cell Networks}, url = {https://m2.mtmt.hu/api/publication/2731962}, author = {Jakó, Zoltán and Jeney, Gábor}, booktitle = {2014 Eighth International Conference on Next Generation Mobile Apps, Services and Technologies (NGMAST)}, doi = {10.1109/NGMAST.2014.16}, unique-id = {2731962}, year = {2014}, pages = {229-234}, orcid-numbers = {Jeney, Gábor/0000-0002-3029-165X} } @article{MTMT:2728581, title = {Outage Analysis of LTE-A Femtocell Networks with Nakagami- m Channels}, url = {https://m2.mtmt.hu/api/publication/2728581}, author = {Jakó, Zoltán and Jeney, Gábor}, doi = {10.1007/s11277-014-1934-5}, journal-iso = {WIRELESS PERS COMMUN}, journal = {WIRELESS PERSONAL COMMUNICATIONS}, volume = {79}, unique-id = {2728581}, issn = {0929-6212}, year = {2014}, eissn = {1572-834X}, pages = {1369-1384}, orcid-numbers = {Jeney, Gábor/0000-0002-3029-165X} } @inproceedings{MTMT:2696340, title = {Application of LTE Small Cells in Urban Environments for Higher Capacity}, url = {https://m2.mtmt.hu/api/publication/2696340}, author = {Jakó, Zoltán and Knapp, Ádám and Imre, Sándor and Jeney, Gábor}, booktitle = {2013 19th IEEE International Conference on Networks (ICON2013)}, doi = {10.1109/ICON.2013.6781965}, unique-id = {2696340}, abstract = {Extending conventional LTE systems with small cells offer new horizon in mobile communications to provide better coverage and enhance capacity.
