Urban facility interconnection networks require a robustness and reliability usually found in public networks or private cable and radio networks in licensed bands. Both factors mean an increase in costs, which also increase as the size of the network increases. The recent rise in use of wireless technologies in open wavebands has attracted the int...

... codec itself therefore generates a fixed delay in frame transmission due to the need to fill it with part of the conversation. The codecs evaluated and their cha- racteristics are shown in Table 1. Figs. 4 show that codec G.711u uses more bandwidth, due to a higher bitrate for a better quality, with less compression complexity. ...

In the near future, RTP/RTCP-based multimedia streaming will become the norm not only in wired networks but also in mobile environments. Presently when a handoff occurs between heterogeneous networks (with different available bandwidths), a RTP sender cannot stream media at a suitable rate over the new network. Furthermore, RTCP fails to precisely...

The nature of playing video streams over a network in a real time requires that the transmitted frames are sent in a bounded delay. Also, video frames need to be displayed at a certain rate; therefore, sending and receiving encrypted packets must be sent in a certain amount of time in order to utilize the admissible delay. There are two main compon...

Wireless Sensor Networks (WSNs) are being used in various applications such as structural health monitoring and industrial control. Since energy efficiency is one of the major design factors, the existing WSNs primarily rely on low-power, low-rate wireless technologies such as 802.15.4 and Bluetooth. In this paper, by proposing , we strive to tackle the challenges of developing ultra-high-rate WSNs based on the 802.11 (WiFi) standard. As an illustrative structural health monitoring application, we consider spacecraft vibration test and identify system design requirements and challenges. Our main contributions are as follows. First, we propose packet encoding methods to reduce the overhead of assigning accurate timestamps to samples. Second, we propose energy efficiency methods to enhance the system’s lifetime. Third, to enhance sampling rate and mitigate sampling rate instability, we reduce the overhead of processing outgoing packets through the network stack. Fourth, we study and reduce the delay of processing time synchronization packets through the network stack. Fifth, we propose a low-power node design particularly targeting vibration monitoring. Sixth, we use our node design to empirically evaluate energy efficiency, sampling rate, and data rate. We leave large-scale evaluations as future work.

Wireless networks, including IEEE 802.11-based or Wi-Fi networks, are inexpensive and easy to install and therefore serve as useful connectivity alternatives in areas lacking wired-network infrastructure. However, IEEE 802.11 networks may not always provide the seamless connectivity and minimal throughput required for Industry 4.0 communications because of their susceptibility to interference from other devices operating in the unlicensed “Industrial, Scientific, and Medical” frequency band. Here we analyzed how a wireless audio transmitter operating on this band influences the throughput of an IEEE 802.11 b/g/n network under laboratory conditions. Wireless audio transmission reduced mean throughput by 85%, rendering the IEEE 802.11 b/g/n network nearly unusable. Our analysis suggests that in order for IEEE 802.11 wireless networks to support Industrial 4.0 applications, attention should be paid to the physical layer as well as the data or upper layers, and critical services should not transmit on the 2.4 GHz band. These findings may contribute to understanding and managing IEEE 802.11 wireless networks in various Industry 4.0 contexts.

In the last years, IEEE 802.11 Wireless LANs (WLANs) have proved their effectiveness for a wide range of real-time industrial communication applications. Nonetheless, the enhancements at the PHY and MAC layers introduced by the IEEE 802.11n amendment have not yet been adequately addressed in the context of industrial communication. In this paper we investigate the impact of some IEEE 802.11n new features on some important performance figures for industrial applications, such as timeliness and reliability.

El uso de las redes inalámbricas tiene un impacto creciente en la industria moderna (sistemas de automoción y fabricación industrial, sistemas distribuidos de supervisión y control...). Especialmente las redes inalámbricas han penetrado de forma rápida en las redes de control que dan soporte a servicios públicos estratégicos (suministro de gas y electricidad, suministro y saneamiento de aguas). Estas redes están formadas por distintas estaciones remotas, una estación central donde se procesa, almacena y controla la información de la instalación y varios clientes remotos que también supervisan y controlan la instalación remotamente. Para comunicar las estaciones remotas con la estación central se utilizan infraestructuras de comunicaciones heterogéneas según las posibilidades y ubicación: xDSL, HFC, WiMAX, GPRS, UMTS, HSDP. Para que el sistema sea eficiente y útil, especialmente en momentos de emergencia, los usuarios ubicados en las estaciones remotas necesitan intercambiar información entre sí o con la estación central. En estos casos, en las estaciones remotas, los propios usuarios que están supervisando el funcionamiento de la instalación haciendo uso de sus dispositivos inalámbricos pueden crear de forma espontánea una red ad hoc móvil útil para el intercambio de información en el caso de que origen y destino no se alcancen directamente. El objetivo global de la tesis es analizar el comportamiento de las MANET en entornos de tipo industrial, tomando como ejemplo una red para el control y supervisión de la red de saneamiento de una gran ciudad, y estudiar cómo afecta a su funcionamiento y a los servicios ofrecidos el movimiento de los nodos. Aunque son muchos los avances realizados en el estudio de las redes ad hoc en los últimos años, aún quedan muchos aspectos que necesitan ser estudiados y mejorados. Pocos han sido los trabajos que evalúen las redes ad hoc con modelos formales.

In recent years, wireless communication has been widely adopted in the field of industrial systems. Compared with traditional wired control and monitoring systems, wireless control and monitoring systems are cost-effective and easy to deploy. On the other hand, IEEE 802.11-based wireless technology is widely applied in many areas due to its popularity, flexibility and ease of management, which makes it a good candidate for various industrial wireless control and monitoring applications with different requirements. However, real-time wireless control and monitoring applications usually have varying degrees of timeliness requirements, and the basic IEEE 802.11 MAC mechanism cannot support such requirements due to its inherent drawbacks. Therefore, in this paper we intend to produce a comprehensive survey and classification of the recent deterministic enhancement approaches in IEEE 802.11 networks, which can be applied in wireless control and monitoring systems with different real-time requirements. We explain each mechanism briefly, and give an extensive comparison of the features (especially the timeliness level)of all described MAC mechanisms. Finally, we conclude this paper by identifying some open research issues for future consideration.

Wireless Local Area Network (WLAN) has enabled greater communication capabilities compared to LAN counterpart. However, when it comes to quality of service (QoS), WLAN has lower reliability, where it has higher latency and packet-loss, especially for real-time streaming applications such as voice over internet protocol (VoIP) and multimedia. Thus, improving QoS in WLAN is a major research challenge, where packet-loss is considered most critical while other factors, such as latency and jitter are acceptable to certain level of tolerance. Theoretically WLAN can provide higher bandwidth and lower latency; however, practical results disagree with this statement. In this paper, we investigated the dilemma using different combination of wireless devices within a local area network to identify the problem. We propose an infrastructure based scheme to improve the QoS for real-time traffic over WLAN. We setup a wireless network using different types of wireless devices and tested VoIP traffic over it. Our simulation results for G.729.2 codec on IPv4 and IPv6 using virtual access point (v-AP) showed better performance than physical access point (ph-AP). We also observed that usage of different wireless devices within a network highly reduced real-time application performance.
