Título : Simulation tool of IEEE 802.11ac wireless networks propagation in indoor environments Autor : Corral González, Pablo; Molina-Galan, Alejandro; Vidal, Jesús; Aljaro Palacios, Miguel; De Scals Martin, GUILLERMO Resumen : This research pretends to be useful for the future deployment of the wireless network of the Universidad Miguel Hernández, specifically at the campus of Elche. In terms of capacity, in short term we will need more capacity in the wireless network, for this reason we are testing some aspects of the protocol IEEE 802.11ac (Wi-Fi 5). This protocol works in the 5 GHz band and provides us more channels and capacity with channel bonding and MIMO. Before the deployment of the wireless network, we need to know the propagation model of the signal in different scenarios and conditions. We analyse the results obtained by a developed software tool capable of representing different measurements of the signal strength with LOS and NLOS scenarios and comparing with indoor propagation models. For measuring the signal level we have used an emitter 3x4 MIMO and a receiver 3x3 MIMO, both compatible with Wi-Fi ac.

Título : Energy benefits of opportunistic device-centric wireless networks Autor : Coll-Perales, Baldomero; Gozalvez, Javier Resumen : Device-centric wireless networks, and in particular Multi-hop Cellular Networks (MCN), can improve the capacity and efficiency of wireless networks, and will hence represent a significant element of the 5G ecosystem. Additional gains can be achieved for mobile delay tolerant services when integrating opportunistic networking in device-centric wireless networks. This paper proposes a solution for such integration that is evaluated for the case of 2-hop uplink opportunistic MCN communications. The proposed solution takes into to account the fact that mobile relays might not always be available at the optimum location and time instant, and the fact that sufficient cellular radio resources might not be available when mobile relays want to start forwarding the information towards the base station. The conducted study shows that the proposed scheme can reduce the energy consumption by more than 80% compared to traditional single-hop cellular communications.

Título : Link-aware opportunistic D2D communications: Open source test-bed and experimental insights into their energy, capacity and QoS benefits Autor : Moraleda-Soler, Alejandro; Coll-Perales, Baldomero; Gozalvez, Javier Resumen : Device-to-Device (D2D) communications can efficiently support the growth in mobile data traffic by offloading part of the traffic from the cellular infrastructure. D2D communications are influenced by the propagation conditions between mobile devices that depend on the antenna heights, presence of obstacles, and mobility of devices. Analytical and simulation studies have shown that link-aware opportunistic transmission schemes can improve the reliability and efficiency of D2D communications. This paper goes a step further and experimentally demonstrates the energy, capacity and Quality of Service (QoS) benefits of link-aware opportunistic D2D communications. This is done through a novel test-bed that is here presented and released open source to the community. The developed test-bed modifies the Linux kernel so that it is independent of the particular hardware being used and can be utilized with Commercial Off-The-Shelf (COTS) equipment.

Título : On the capability of multi-hop cellular networks with mobile relays to improve handover performance Autor : Coll-Perales, Baldomero; Gozalvez, Javier Resumen : Traditional single-hop cellular architectures fail to provision high and homogeneous quality of service (QoS) levels throughout a cell area. In addition, the performance and optimization of handover mechanisms poses significant challenges due to degraded channel conditions at the cell boundaries. In this context, multi-hop cellular networking technologies have been identified as an attractive solution to overcome traditional cellular limitations and improve the performance in handover areas. This paper discusses a novel handover process using multi-hop cellular networks with mobile relays (MCN-MR), and illustrates the benefits of this approach over traditional cellular handovers through field tests.

Título : An IEEE 802.11 MAC Software Defined Radio implementation for experimental wireless communications and networking research Autor : Gutierrez-Agullo, Juan R.; Coll-Perales, Baldomero Resumen : Wireless ad-hoc networking will be a fundamental component of emerging technologies such as multi-hop cellular networks, vehicular ad-hoc networks and wireless mesh networks, with most of these technologies based on evolved versions of the 802.11 standard. To achieve their expected benefits, and address their challenges, in terms of energy efficiency, reliability or reconfigurability, advanced cooperative and cross-layer communications and networking techniques need to be investigated. Most of the studies conducted to date are based on analytical and simulation techniques, and the use of commercial hardware equipment usually lacks the flexibility needed to conduct advanced research studies. In this context, this paper presents a fully programmable Software Defined Radio implementation of the IEEE 802.11 MAC that can be used, configured and fully modified, to develop advanced cross-layer communications and networking techniques.
