This article consists of a slide from the authors' conference presentation. NMI is an abstracted, unified memory interface to support future scale-out memory capacity, processing-in-memory, I/O devices, emerging non-volatile memories, cache-coherent shared virtual memory.
Cyber-physical systems (CPSs) are a new paradigm of control systems where control, communication, and computation fields intersect. Applications of such systems are expected to play an important role in many domains in the future. This includes critical domains such as transportation and health domains. Hence, it is quite important for such systems to operate reliably. Moreover, many CPS applications...
Timeliness and reliability are two major requirements of control systems and this true, in particular, in many industrial application areas which make use of solutions distributed over a network. Moreover, with the adoption of wireless communication technologies in industrial environments, granting timeliness and reliability for transmissions over the wireless error-prone channel has become a challenge...
In this paper we propose a novel co-allocation scheme, called a Reliable Multicast Brute-Force co-allocation scheme (ReMBF for short), which employs a reliable multicast (RM for short) technique with the Brute-Force (BF for short) scheme to accelerate data retrieval and delivery, and reliably transmit data to its users for data grids. Several types of data access patterns, including Zipf-like, geometric,...
Gathering information efficiently from a, possibly fragmented, sensor network presents a serious problem in disaster recovery applications. Unless a transmission control mechanism exists, a sink can be flooded with information sent by sensors, or sensor transmissions may be lost on their way to the sink. Consequently, there is a necessity for a reliable protocol that automatically and speedily adapts...
Body sensors have gained increasing interest during the past several years. With more applications deployed, it is imperative to ensure the success of data analysis, which largely depends on data transmission reliability as well as the importance of samples received. Traditional approaches focus on improving data reliability through various schemes such as prioritization of MAC access. In this paper,...
Software Defined Networking (SDN) and Named Data Networking (NDN) are two topics which have received lots of attention in the networking research community in recent years. While both have emerged independently from each other we believe that their core features can be well aligned to each other. Hence combining both may hold potential benefits for network operators. In this paper we investigate the...
In order to meet different requirements of rechargeable batteries in Electric vehicles, a charger with hybrid structure, which designed as module and combined in series and parallel, was proposed in this paper. Each individual module uses ZCS phase-shifted full-bridge converters. And in order to ensure power sharing of each module, the outer loop power control strategy based on average current sharing...
The fifth generation (5G) of cellular networks is starting to be defined to meet the wireless connectivity demands for 2020 and beyond. One area that is considered increasingly important is the capability to provide ultra-reliable and low-latency communication, to enable e.g., new mission-critical machine-type communication use cases. One such example with extremely demanding requirements is the industrial...
We demonstrate sub-5nm filament based electrochemical metallization RRAM with self-limited program in a reliable and controllable manner. This RRAM removes the necessity for any external current compliance in a 1TnR (1S1R) architecture. Furthermore, we report a novel technique to amplify RRAM's intrinsic ON/OFF resistance ratio by a factor of >104, which offers significant cell-, circuit- and system-level...
The digital contents in large distributed storage systems may have different reliability and access delay requirements, and for this reason, erasure codes with different strengths need to be utilized to achieve the best storage efficiency. At the same time, in such large distributed storage systems, nodes fail on a regular basis, and the contents stored on them need to be regenerated and stored on...
We propose a base-station (BS) cooperation model for broadcasting a discrete memoryless source in a cellular or heterogeneous network. The model allows the receivers to use helper BSs to improve network performance, and it permits the receivers to have prior side information about the source. We establish the model's information-theoretic limits in two operational modes: In Mode 1, the helper BSs...
Fifth generation wireless networks are currently being developed to handle a wide range of new use cases. One important emerging area is ultra-reliable communication with guaranteed low latencies well beyond what current wireless technologies can provide. In this paper, we explore the viability of using wireless communication for low-latency, high-reliability communication in an example scenario of...
The Portals 4 network specification is a low-levelAPI for high-performance networks developed by Sandia National Laboratories, Intel Corporation, and the University of NewMexico. Portals 4 is specifically designed to support both the MPIand PGAS programming models efficiently by providing building blocks upon which to implement their particular features. In this paper we discuss our ongoing efforts...
The device people use to capture multimedia has changed over the years with the rise of smart phones. Smart phones are readily available, easy to use, and capture multimedia with high quality. While consumers capture all of this media, the storage requirements are not changing significantly. Therefore, people look towards cloud storage solutions. The typical consumer stores files within a single provider...
Vehicular Ad hoc Networks (VANETs) play an important role in future, for on road V2V communication systems and related applications like self-organizing, acquiring traffic information using sensors and disseminating it to the nearby vehicles, which are based on broadcast/geo-cast transmission schemes. These networks allow vehicles to share traffic, alerting information with each other during travelling...
Network virtualization as an important research, will have a far-reaching effect on next generation network. However, the current studies of virtual network (VN) pay more attention to the utilization of the substrate network (SN) and optimization of mapping algorithms, whereas the course of mapping they ignore some serious weaknesses such as substrate network's high availability. This paper we forces...
This paper addresses an NP-hard problem, called NTD-CB/R, whose solution is of importance to applications requiring one or more Quality of Service (QoS). Specifically, the problem calls for a network topology that meets two objectives, i.e., minimal cost and maximum bandwidth, subject to a predefined (s, t) reliability constraint. We approach the problem by converting it into one with a single objective...
Packet (MPLS-TE) over optical transport networks offer a two-phase restoration procedure against single and multiple concurrent equipment failures, i.e., a relatively faster restoration scheme at the MPLS layer and a relatively slower restoration scheme at the optical layer. This two-phase procedure can be leveraged to efficiently handle network recovery from a disaster-type scenario, while accounting...
A magnetic tripolarization antenna is proposed for DSRC (Dedicated Short Range Communication) applications. A conventional patch antenna, which is usually used to generate the horizontal polarization, is modified to generate the perpendicular polarizations by including the ring slots. The opposite currents flowing the upper and under conductors generate loop current. For the horizontal polarization...
