The design space exploration of Networks-on-Chip (NoC) requires tools to evaluate the network performance, tune its parameters and achieve the requirements of the target application. In this context, this paper presents RedScarf, a simulation environment with graphical user interface and a set of tools that automate the design space exploration of NoCs. It presents many resources that make RedScarf...
Nowadays, systems for various smart city industries such as city power plants, public transportation and integrated modular avionics are becoming increasingly complicated, with most of components being embedded and geologically distributed. In order to ensure the availability of target systems, prognostic and health management develops as an important system to assess the current health state and...
This paper presents an efficient new snapshot mechanism, briefed as Live Save, to make real time backup of the VM state to the local host. The proposed Live Save will iteratively send the state data, store the snapshot file in the local host and send the entire file directly to a remote host when necessary - to save significant bandwidth consumption. We also set up an advanced Improved Live Save which...
As cloud computing continues to gain momentum, big data analytics are now offered as Software as a Service (SaaS). Besides the heterogeneity and multi-tenancy of the underlying virtualized environment, scheduling such real-time, data-intensive, embarrassingly parallel applications in a SaaS cloud involves another serious challenge: data locality. Consequently, data-aware scheduling policies should...
Debriefing is the practice of after session review of training performance to enhance self-reflection through feedback. It has been considered as a vital and crucial part of simulation-based medical training. However an accurate, objective and in-depth evaluation of trainee performance has been a significant challenge. To address this we developed a knowledge-based framework in which the criteria...
Human behaviors may change over time, but people always tend to preserve their preference. People typically like similar types of contents, for example, movies that they watch in regular intervals with the same amount of interests. On the other hand, the Internet is moving towards a content-oriented structure from the host-oriented structure. Content-Centric Networking (CCN), a content-oriented paradigm,...
Smart space is created by deploying a Semantic Information Broker (SIB) in a given Internet of Things (IoT) environment. The deployed SIB enables information sharing for many digital devices participating in the IoT environment. In this study, we consider CuteSIB — a new SIB implementation for the Smart-M3 platform, where the class of SIB host devices covers various embedded and mobile devices, in...
Modeling and Simulation (M&S) has become an essential tool in the development, testing and verification of operational software in a complex multi-domain, multi-threaded heterogeneous system of systems environment. The complex systems of today encompass mix of hardware sub-systems (with varying degree of capabilities), software environments (comprising a plethora of development environments, operating...
A thermoelectric generator (TEG) can be defined as a low voltage high-current dc power with a linear I-V feature. Even though efficiencies for TEGs are as low as 3-5%, useful electricity generation is possible due to the great amount of heat emitted from almost any electric device. The idea is to convert the thermal energy from any source releasing waste heat directly to electrical energy by a thermoelectric...
This paper presents a bit-level parallel communication interface used for inter processor communication separated on different printed circuit boards. A high performance board-to-board communication interface is important in modern supercomputers and portable computers or gadgets with multiple screen displays. We propose a recalibrated transmitter and receiver soft IP cores to support asynchronous...
Efficient content retrieval is crucial for Named Data Delay Tolerant Networking (NDDTN). Previous studies have shown that using social properties reasonably can improve availability of forwarding data packets, reduce overhead and delay. In this paper, a forwarding strategy, called RIF based on Region of Interest (ROI), is proposed and put forward for NDDTN. RIF computes cumulative visiting time and...
Edge cloud computing is a trending paradigm, which extends cloud computing by additionally utilizing computing resources at the network edge, e.g., at mobile base stations. Especially personalized services can be instantiated or migrated close to end users, which improves the latency and supports user mobility. However, the placement of the service chains is crucial for the performance of the services...
This paper evaluates the performance of the first-last-exact fit spectrum allocation policy for elastic optical networks. The first-last-exact fit spectrum allocation policy is intended to increase the number of aligned available slots and avoid small contiguous available slots, and hence suppresses the blocking probability. This policy separates the allocation of disjoint and non-disjoint connections...
In this work, we investigate the dual gate positive feedback field-effect transistor (FBFET) using DC and transient TCAD simulation. I-V characteristics, subthreshold swing, and transient characteristics are analyzed. The FBFET has steep switching property and low off current. We design an inverter that can low power operate with the FBFET. By using the FBFET, the stand-by current is effectively suppressed...
In this paper, we propose a 1-bit Full Adder circuit built with Ballistic Deflection Transistors (BDT). BDT is a disruptive technology based on AlGaAs/InGaAs heterostructure. Different combinational circuits were successfully realized using BDT NAND gate and General Purpose Gate (GPG) structures. The developed circuit is an extension of BDT GPG and different from that of the previously implemented...
In order to cope with the exponential growth of mobile traffic, mobile operators need to access more spectrum resources. LTE in unlicensed spectrum (LTE-U) has been proposed to extend the usual operation of LTE in licensed spectrum to cover also unlicensed spectrum. However, this extension poses significant challenges especially regarding the coexistence between LTE-U and legacy systems like Wi-Fi...
It is believed that drift current dominates the whole current behavior in long channel device as VGS > VT. However, when the device is kept scaling down until nano-node generation, some issues like velocity saturation and velocity overshoot occur constantly. These two issues give us a significant challenge to estimate the drain current. In the nano range of device size, we find that the I-V model...
Recently, the problem of using efficient limited number of mobile devices to go to charge and collect data of sensors such that sensors can work forever has received a great deal of attention in Wireless Rechargeable Sensor Network (WRSN). Many methods have been proposed for the WRSN systems such that mobile device can charge and collect data from sensors. However, most of previous works often require...
Fog computing is a model in which data and processing are concentrated on devices at the edge of the network, rather than almost entirely in the cloud. This new paradigm tries to solve the latency and bandwidth issues that the current cloud systems have to deal with, and also addresses the scalability problems caused by the exponential growth of the number of smart devices due to the success of the...
Wireless sensor networks (WSNs) usually build from huge number of randomly deployed sensor nodes in certain area. The sensors are mainly utilized to monitor physical and environmental conditions, gather information, process this data locally and transfer the sensed data back to the Base Station (BS). The main objective of this paper is to simulate, evaluate and observe the behavior of developed clustering...
