When the Great East Japan Earthquake occurred in 2011, telephone and Internet could not be used in many cases. To achieve network availability in disaster situations, we propose the traffic control system based on SNS information. In order to utilize the data of packet payload obtained from SNS, deeply programmable network (DPN), which is extending SDN as implementing programmable data plane and API...
5G networks are expected to support significantly higher data rates than legacy networks through ultra-dense deployment of networks, higher system bandwidths and higher spectral efficiency. Such networks would also be supporting a diverse set of use cases in order to provide connectivity solutions for other industry verticals. One of the key requirements of 5G is to support all these enhancements...
5G Networks are anticipated to provide a diverse set of services over Network Slices (NS) using Network Function Virtualization (NFV) technologies. We propose solutions to enable NS selection and routing of traffic routing through a NS. A framework for enabling negotiation, selection and assignment of NSs for requesting applications in 5G networks is presented. A definition for service description...
In this paper we present the Automatic Distribution System (ADS). ADS is a novel framework that enables quick development and deployment of 5G radio access networks. ADS automatically parallelize radio algorithms and distributes their execution among standard servers in order to fulfill their real-time constraints and minimize power consumption. ADS was at the operational heart of the first large-scale...
The error performance of fixed access and home (FA&H) technologies is an important physical layer (PHY) characteristic that has strong impact on the end-user's experience. However, different FA&H technologies employ different approaches to define their error performance, making it difficult to compare or align technologies. In this paper, we present the, to our knowledge, first unified comparison...
An important aspect in providing Internet access is the cost for both fronthaul as well as backhaul connectivity, ultimately providing the access to the wider Internet content and services to the local community. The proliferation of media-rich content has led to a dramatic increase of backhaul costs, while creating pinching points in the often also limited fronthaul network that faces the end users...
Low Power and Lossy Networks (LLNs) have a crucial role in the Internet of Things (IoT) paradigm. For the IPv6 Routing Protocol for LLNs (RPL), two objective functions (OF) have been standardized so far, namely (Objective Function zero (OF0), and the Minimum Rank with Hysteresis Objective Function (MRHOF). However, these particular objective functions are used to build a topology where bottleneck...
In this paper, we present pulse shaped OFDM as an enabler for a flexible PHY design of the air interface for 5G. After introducing the waveform details and its degrees of freedom provided for the system design, we describe the suitable parameterizations to be considered for addressing the diverse requirements envisaged for future 5G systems, which are derived from the broad range of services and frequencies...
Narrow band Internet of Things (IoT), based on legacy Long Term Evolution (LTE) system, is a hot cellular technology to support sensors and controllers applications. However, its paging capacity is insufficient if legacy paging mechanism is employed, due to the contradiction between the massive devices and the limited physical band resources. In this paper, a more efficient paging message is designed...
The Internet of Things (IoT) enables the connections of billions of devices to the Internet. It is thus very important to effectively manage this huge amount of devices. Among many available device management protocols, Open Mobile Alliance Lightweight M2M (OMA LWM2M) has been adopted by the global M2M standards, ETSI M2M and oneM2M as the standard for device management. However, OMA LWM2M-supported...
IEEE 802.15.4e Time Slotted Channel Hopping (TSCH) standard has gained a lot of attention within the Industrial Internet of Things research community due to its effectiveness in improving reliability and providing ultra-low power consumption for industrial applications, and in which its communication is orchestrated by a schedule. Despite its relevance, the standard leaves out of its scope in defining...
Medical devices at the point-of-care can be interconnected through standardised communication protocols to build an Integrated Clinical Environment (ICE), but in order to interoperate with clinical information systems, different data exchange standards need to be conformed to. The emerging HL7 Fast Healthcare Interoperability Resources (FHIR) framework appeals to developers and clinicians alike and...
This paper provides a progress report on our project to advance and integrate knowledge of Telecommunication Standards into STEM Education. We discuss the problems facing standards education in US universities and outline the motivations for this project This is followed by an overview of the project's philosophy, organization, activities, and a description of the new course we are developing as a...
Bluetooth Low Energy (BLE) Advertising is an important component of BLE as it is used to broadcast connection information to other devices nearby, usually smartphones. Furthermore, it is the foundation of a variety of services, such as indoor localization. We present a selective jammer against BLE beacons. The jammer selectively jams only BLE advertising beacons for which it was configured (API) on...
In next generation wireless LAN standard which is called IEEE802.11ax, Orthogonal Frequency Division Multiple Access (OFDMA) random access has been adopted as an uplink multi-user transmission technology. In this paper, we propose an adaptive backoff algorithm for OFDMA random access. Due to the finite service period defined by the standard, random access OFDMA sessions are discontinuous in time which...
This paper considers a hybrid two-stage space-time receiver structure for uplink millimeter wave (mmW) based systems, where the user terminals (UTs) and the base station (BS) are equipped with a large antenna array and the number of radio frequency (RF) chains is lower than the number of antennas. In the first stage the analog transmit and receive beam-formers/precoders are computed for each UT —...
Small cell deployments are one of the most significant long-term strategic policies of the mobile network operators since small cell architecture delivers not only the required capacity boost but also the flexibility important for immensely-localized deployments in high-traffic environments. In HetNets, small cells serve as offloading spots in the radio access network to offload users and their associated...
The 5th Generation (5G) of wireless mobile communication systems is currently the focus of many research projects and standardization bodies, such as the 3rd Generation Partnership Project (3GPP). Accurate modeling of the radio propagation channel is important for evaluating the performance of candidate technologies for 5G. However, the state-of-the-art radio channel models, such as the 3GPP 3D channel...
