Achieving a tighter level of aggregation between LTE and Wi-Fi networks at the radio access network (a.k.a. LTE-Wi-Fi Aggregation or LWA) has become one of the most prominent solutions in the era of 5G to boost network capacity and improve end user's quality of experience. LWA offers flexible resource scheduling decisions for steering user traffic via LTE and Wi-Fi links. In this work, we propose...
With emerging deep submicron technology, device variations limit the SRAM performance and yield. Cell stability defined by the Static Noise Margin (SNM) of the SRAM cell among other figure of merits (FOMs) governs the yield in SRAMs. Variations in the scaled SRAMs increase the probability of cells becoming weak. To ensure reliability of SRAMs it is important to identify such cells post fabrication...
In Opportunistic Networks (Oppnets), a permanent fixed path is never assumed to be available between the source and destination. Nodes are not aware of changing network topology. So, static routing is not possible here and dynamic routing is best suited for such networks. In this paper, a Cloud Computing Based Routing Protocol (CCBRP) has been proposed for infrastructure-based Oppnets. It uses the...
In advanced technology nodes, device variations limit the SRAM performance and yield. Cell stability defined by the Static Noise Margin (SNM) of the SRAM cell primarily governs the performance with respect to yield in SRAMs. Variations in the scaled SRAMs increase the probability of cells becoming weak. To ensure reliability of SRAMs it is important to identify such cells post silicon. In this work,...
In this work, a novel architecture of Secure Hash Algorithm-1(SHA-1) for increased throughput and reduced area is presented. Various acceleration techniques are applied such as pre-computation, loop unfolding, and pipelining simultaneously. Carry Save Adder using Carry Lookahead Adder in its final stage is used for multi-input addition function to achieve high performance. The proposed architecture...
Competition is always a good thing in IT world. It forces us to do our best. Nowadays, in the area of cloud computing, it is at the peak between the larger number of cloud users and cloud providers who view for the opportunity to use and provide services. Competition among cloud users means the price of cloud services never fall very low and between cloud providers mean the price of services never...
DevOps presents a significant broader perspective in delivering software solutions. The perception of DevOps being a mere tool has been formulated into a change in culture, paradigms in automation, clarity in measuring risks and facilitating ease of sharing. DevOps has been responsible for companies to move from a monolithic pace of software releases to an agile mindset. This paper discovers the significance...
Human body implants, portable electronic gadgets and a number of distributed sensor network applications required low power as well as low energy consuming electronic circuits. Most of such electronic circuits need analog to digital converters also. In this paper the authors are proposed a design of the level crossing analog to digital converter (LC-ADC) architecture. The proposed circuit has been...
In integrated circuits, time resolution is preferred over voltage resolution as it offers larger operating range. Time difference amplifiers are also useful in measurement of small phase differences. A simple but high gain Time Difference Amplifier (TDA) is presented in this paper. The TDA amplifies the width of a pulse for precise measurement of time difference. The pulse width amplification is achieved...
In Wireless Local Area Networks (WLANs), providing seamless mobility and balancing load among Access Points (APs) are challenging issues due to simple signal strength based association and hand-off mechanisms employed at wireless clients. Extensions to Software Defined Networking (SDN) framework for wireless networks could help to address theses issues in an efficient and cost-effective manner with...
In this paper, a novel method for lossless compression of video is proposed. Almost all the prediction based methods reported in literature are of two pass. In the first pass, motion compensated frame is obtained and in the second, some sophisticated method is used to predict the pixels of the current frame. The proposed method is an efficient replacement for the first method that predicts current...
Retaining students poses a huge challenge in the field of engineering, as many students become discouraged while working on their degrees and switch majors or leave school entirely. Our key observation is that it is extremely important to introduce students to real-world problems early on in their studies. Too often, students become confused and dissatisfied by abstract theories in their early engineering...
Distributed network of sensors form a deployable key to information with self organizing capabilities from smart environments (building, home, utilities, industrial, transportation etc). In this paper we present the vision of wireless sensor network (WSN) which enables the interconnectivity that extends the reach of cyberspace out into the physical world with the low cost, high sensing fidelity, flexibility,...
We present elements of a pervasive computing enabled modeling environment for integrated national energy systems (CI-MINES) to support policy and decision making as it pertains to co-evolving socio-energy systems. Decision support systems built using CI-MINES will provide public policy makers as well as private stakeholders entirely new ways to design and architect next-generation energy systems....
