Future tactical communications involves high data rate best effort traffic working alongside real-time traffic for time-critical applications with hard deadlines. Unavailable bandwidth and/or untimely responses may lead to undesired or even catastrophic outcomes. Ethernet-based communication systems are one of the major tactical network standards due to the higher bandwidth, better utilization, and...
This paper investigates the use of ultra-wideband (UWB) radio for communication in industrial wireless sensor networks (WSNs). OpenWSN is an open-source IPv6 mesh network protocol stack based on IEEE 802.15.4 time slotted channel hopping (TSCH). We adapted OpenWSN to operate an UWB physical layer based on the DecaWave DW1000 UWB transceiver. Experiments were conducted in an industrial steam heating...
Time sensitive networking becomes increasingly important in handling control and management information. Utilization of the existing infrastructure is considered to be an important issue due to the increasing demand. Since control/management data packets can use the existing infrastructure, this work study the basic requirements behind the Time Sensitive Network and ingress policies in it. Further...
Modern distributed embedded systems frequently involve wireless communication nodes where messages have to be delivered within given timing constraints. This goal can be achieved by adopting a suitable real-time communication protocol. In addition, connecting such systems with mobile devices is also desirable for performing configuration, monitoring, and maintenance activities. The Bluetooth low energy...
Stream Control Transmission Protocol (SCTP) is one of the TCP/IP protocol stack transport protocol. In this paper we aim for improving the video transmission rates by significantly enhancing the SCTP protocol frame structures. We make use of SCTP multi-streaming feature for determining various frame formats that defines the effective transmission. The proposed unidirectional delay technique is used...
Adaptive bitrate streaming protocols, such as DASH, have seen extensive interests for their adaptation capabilities to increase consumers' Quality of Experience (QoE) over the Internet, and have become de-facto standards in web video delivery. Compared with traditional single-server approaches, multiple-server streaming offers the opportunity to exploit expanded bandwidth, link diversity, and reliability...
Summary form only given. The complete presentation was not made available for publication as part of the conference proceedings. In this half day tutorial, we present an overview of the JESD204 interface protocol, key performance metrics and challenges in an embedded silicon implementation. We discuss system budgeting of the jitter components in the physical channel and present tradeoffs to meet the...
Trust-ND is an alternative lightweight security mechanism based on distributed trust management model to secure IPv6 Neighbor Discovery Protocol. Trust-ND introduced a new NDP option, called Trust option, with three fields: Message Generation Time (or timestamp), Nonce, and Message Authentication Data. A thorough investigation and analysis of the use of timestamp field has identified four scenarios...
Software-Defined Networking (SDN) provides the potential for highly configurable, automated networks by separating the control and forwarding functions of network devices. While SDN appears to have many potential benefits for coalition tactical networking, including rapid reconfigurability and improved network situational awareness, there are significant obstacles to overcome. In particular, the low...
Software-Defined Networking (SDN) is an emerging networking paradigm aims to improve network management flexibility and efficiency. OpenFlow is the popular SDN de-facto standard, which has been prevalently adopted by both academia and industry for research and development purpose. OpenFlow provides rich programmable interface to network administrator to ease traffic monitoring and control. Because...
Time-Sensitive Networking (TSN) standards aim to support hard real-time communication with minimum latency based on Ethernet technology. They can also support the automotive domain considering upcoming and challenging application requirements in intelligent vehicles of the future. Despite all advantages, Time-Aware Shaper (TAS), a significant feature of TSN, increases the network configuration overhead...
This electronic document is a “live” template and already defines the components of your paper [title, text, heads, etc.] in its style sheet. Video streaming is a technique for distributing media content, in which it is not necessary for the streams of the requested file to arrive in full in order to begin playing the video. Traditionally, streaming has been supported by RTP and RTSP protocols, requiring...
This paper describes industry efforts to develop an underwater acoustic communications standard for the offshore energy community. The Subsea Wireless Group (SWiG), an international oil and gas industry network comprising operators, installers, and technology companies, assessed a variety of potential use cases and possible routes to develop a common standard, culminating in the selection of the JANUS...
The new CAN-FD standard for automotive communication provides support for real-time predictability at an increased rate and with a larger payload than the existing CAN standard. The adoption of CAN-FD requires the migration and possibly the redesign of the existing message sets to exploit the features of the protocol, by repacking the application signals in the new larger frames. Previous works provided...
Currently, Quantized Congestion Notification (QCN) has been accepted as the standard layer 2 congestion control protocol in Data Center Ethernet. Although the good performance of QCN has been validated in many experiments, we find that QCN has two drawbacks. First, the incomplete binary search in QCN fails to find the proper sending rate, leading to complicate supplement mechanisms. Second, in face...
Over the past few years, adaptive bitrate streaming protocols, such as DASH, have risen to enhance the End-Users' experience towards video consumption over the Internet. Current methods perform a smoother playback (i.e., fewer re-buffering states) trading off with quality fluctuations due to the client-server link state. The proposed work goes a step further and introduces an innovative lightweight...
This paper deals with the designing an interface between AXI Protocol based system and DDR3 Memory. It enables an AXI host to read and write data in a DDR3 Memory. It has been designed to utilize the DDR3 interface for maximum throughput. It implements FIFO where it stores the write command and writes data and passes it to DDR3 Memory. Similarly, it collects data from DDR3 Memory and stores in a FIFO...
As the number of Electronic Control Unit increased in automotive system, its memory capability and functionalities have also increased in large scale. These large number of high functional Electronic Control Units (ECU) in vehicle system demand for high data rate connectivity to external network and within in-vehicle network. This high data rate requirement lead to the introduction of Ethernet Technology...
This paper investigates the characteristics of Tahoe, Reno, New Reno, Vegas, and Sack, and calculated their throughputs in simulated environment using NS-2 simulator by varying various performances parameters such as bandwidth, simulation time and number of traffic sources in order to figure out which one of them is the best for which scenario.
