    Article
    Open Access
    Dense deployments of Small Cells are key to fulfill the capacity requirements of future 5G networks. However, two roadblocks to the adoption of Small Cells are i) the limited availability and the cost of sites with wired ...
  • Optimization-oriented RAW modeling of IEEE 802.11ah heterogeneous networks 

    Tian, Le; López Aguilera, M. Elena; García Villegas, Eduard; Tetemke Mehari, Michael; De Poorter, Eli; Steven, Latre; Famaey, Jeroen (2019-09-13)
    Article
    Open Access
    The new medium access method of IEEE 802.11ah, called Restricted Access Window (RAW), divides stations into different groups, and only allows stations in the same group to access the channel simultaneously, in order to ...
  • Maximizing Infrastructure Providers' Revenue Through Network Slicing in 5G 

    Vincenzi, Matteo; López Aguilera, M. Elena; García Villegas, Eduard (Institute of Electrical and Electronics Engineers (IEEE), 2019-09-09)
    Article
    Open Access
    Adapting to recent trends in mobile communications towards 5G, infrastructure owners are gradually modifying their systems for supporting the network programmability paradigm and for participating in the slice market (i.e., ...
  • Stateless multicast protocol for ad-hoc networks 

    Feng, Chen-Hsiang; Zhang, Yuqun; Seyfettin Demirkol, Ilker; Heinzelman, Wendi (2012-02)
    Article
    Restricted access - publisher's policy
    Multicast routing protocols typically rely on the a priori creation of a multicast tree (or mesh), which requires the individual nodes to maintain state information. In dynamic networks with bursty traffic, where long ...
  • UPS: Universal Protocol Stack for emerging wireless networks 

    Feng, Chen-Hsiang; Seyfettin Demirkol, Ilker; Heinzelman, Wendi (Elsevier, 2013-03)
    Article
    Restricted access - publisher's policy
    Recent devices developed for emerging wireless networks, such as 4G cellular networks, wireless mesh networks, and mobile ad hoc networks, support multiple communication substrates and require execution of multiple protocols ...
  • Supporting bursty traffic in wireless sensor networks through a distributed advertisement-based TDMA protocol (ATMA) 

    Ray, Surjya; Seyfettin Demirkol, Ilker; Heinzelman, Wendi (Elsevier, 2013-05)
    Article
    Restricted access - publisher's policy
    Nodes in wireless sensor networks (WSNs) are battery powered and oftentimes deployed in remote and hostile locations. Energy conservation is, therefore, one of the primary goals of MAC protocols designed for these networks. ...
  • Design and implementation of a Wake-up Radio receiver for fast 250 kbps bit rate 

    López Aguilera, M. Elena; Hussein, Maison; Cervià Caballé, Martí; Paradells Aspas, Josep; Calveras Augé, Anna M. (2019-12)
    Article
    Open Access
    Wake-up radio (WuR) systems have appeared as a solution for reducing power consumption. As IEEE 802.11 is the preferred radio technology, IEEE 802.11 task group TGba focuses on the IEEE 802.11-based WuR standardization. ...
  • Adaptive sensing and optimal power allocation for wireless video sensors with sigma-delta imager 

    Malijan, Marisa; Seyfettin Demirkol, Ilker; Maricic, Daniel (2010-10)
    Article
    Open Access
    We consider optimal power allocation for wireless video sensors (WVSs), including the image sensor subsystem in the system analysis. By assigning a power-rate-distortion (P-R-D) characteristic for the image sensor, we build ...
