    Software-Defined Networks (SDN) can be seen as a promising alternative to achieve the long-awaited power efficiency in current communications systems. In these programmable networks a power-aware mechanism could be easily ...
  • Spectrum trading in virtualized multi-tenant 5G networks 

    Tsirakis, C.; López Aguilera, M. Elena; Matzoros, P.; Agapiou, George; Varoutas, D. (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Open Access
    In this research work, we analyze the problem of spectrum trading in virtualized multi-tenant 5G networks using principles from matching theory. More specifically, we deal with the matching problem among the Mobile Network ...
  • Heuristic methods in geographical routing protocols for VANETs 

    Urquiza Aguiar, Luis; Almeida, Daniel; Tripp Barba, Carolina; Aguilar Igartua, Mónica (Association for Computing Machinery (ACM), 2015)
    Conference report

    This paper proposes different local\hyph search heuristics to improve the performance of geographical routing protocols in VANET networks, which typically relies the selection of the next node only on the best candidate. ...
  • Two way molecular communications 

    Kwack, J.W.; Yilmaz, Hüseyin Birkan; Farsad, Nariman; Chae, Chan-Byoung; Goldsmith, Andrea (Association for Computing Machinery (ACM), 2018)
    Conference report
    Restricted access - publisher's policy
    For nano-scale communications, there must be cooperation and simultaneous communication between nano devices. To this end, we investigate two way (a.k.a. bi-directional) molecular communications between nano devises. By ...
  • Towards an integral model-based simulator for autonomous earth observation satellite networks 

    Ruiz De Azúa Ortega, Juan Adrián; Araguz López, Carles; Calveras Augé, Anna M.; Alarcón Cot, Eduardo José; Camps Carmona, Adriano José (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report

    During these years, novel Distributed Satellite Systems (DSS) have disrupted traditional space segment paradigms. In particular, Federated Satellite Systems and fractionated spacecraft have explored the benefits of interacting ...
  • Performance analysis of power adjustment methods in molecular communication via diffusion [Difuzyon ile moleküler iletisimdeki guç ayarlama metodlarinin performans analizi] 

    Turan, Meriç; Tugcu, Tuna; Yilmaz, Hüseyin Birkan (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Restricted access - publisher's policy
    In this paper, performance of binary concentration shift keying (BCSK), BCSK with power adjustment (BCSK-PA), and BCSK with consecutive power adjustment (BCSK-CPA) are analyzed in terms of bit error rate (BER), energy, and ...
  • Mean waiting time in the M/H2/s queue: application to mobile communications Systems 

    Barceló Arroyo, Francisco; Paradells Aspas, Josep; Aguilar Igartua, Mónica (Wissenschaft & Technik, 1997)
    Conference lecture
    Open Access
    In this paper a procedure to approximately calculate the mean waiting time in the M/H2/s queue is presented. The approximation is heuristic although based in the intuitive symmetry between the deterministic and balanced ...
  • The roll of Data Distribution Service in failure-aware SDN controllers 

    Llorens Carrodeguas, Alejandro; Cervelló Pastor, Cristina; Leyva Pupo, Irian; Navarro Ortiz, Jorge; López-Soler, Juan Manuel (Unión Científica Internacional de Radio (URSI), 2018)
    Conference report
    Restricted access - publisher's policy
    The necessity of a flexible, scalable, faster and programmable network to offer new services are challenging to telecommunication operators. These characteristics along with robustness and availability are essential in ...
  • A latency-constrained framework for edge nodes placement optimization in 5G networks 

    Santoyo González, Alejandro; Cervelló Pastor, Cristina (Unión Científica Internacional de Radio (URSI), 2018)
    Conference report
    Restricted access - publisher's policy
    Latency is a main challenge for most 5G use cases, since mission critical environments are mostly delay sensitive. Edge Computing has become the main technological candidate to overcome this problem. However, under such ...
  • A framework for placement and optimization of network functions in 5G 

    Leyva Pupo, Irian; Cervelló Pastor, Cristina; Llorens Carrodeguas, Alejandro (Unión Científica Internacional de Radio (URSI), 2018)
    Conference report
    Restricted access - publisher's policy
    In this paper, we propose an architecture for the 5G core network using Software Defined Networks (SDN) and Network Functions Virtualization (NFV) technologies. Moreover, based on this architecture, we design a framework ...
