eDSA: Energy-Efficient Dynamic Spectrum Access Protocols for Cognitive Radio Networks Abstract?In this paper we propose a class of energy-efficient dynamic spectrum access (DSA) protocols for secondary user (SU) communication over a single primary user (PU) channel. The proposed variants of DSA can be optimized with respect to different back-off strategies and SU packet lengths. <...
Efficient and Consistent Path Loss Model for Mobile Network Simulation Abstract?The accuracy of wireless network packet simulation critically depends on the quality of wireless channel models. Path loss is the stationary component of the channel model affected by the shadowing in the environment. Existing path loss models are inaccurate, require excessive measurement or computational overhead,…
Energy and Area Efficient Three-Input XOR/ XNORs With Systematic Cell Design Methodology Abstract?In this brief, we propose three efficient three-input XOR/ XNORcircuits as the most significant blocks of digital systems with a new systematic cell design methodology (SCDM) in hybrid-CMOS logic style. SCDM, which is an extension of CDM, plays the essential role in designing…
High Speed and Energy Efficient Carry Skip Adder Operating Under a Wide Range of Supply Voltage Levels Abstract?In this paper, we present a carry skip adder (CSKA) structure that has a higher speed yet lower energy consumption compared with the conventional one. The speed enhancement is achieved by applying concatenation and incrementation schemes to improve…
Low-Cost High-Performance VLSI Architecture for Montgomery Modular Multiplication Abstract?This paper proposes a simple and efficient Montgomery multiplication algorithm such that the low-cost and high-performance Montgomery modular multiplier can be implemented accordingly. The proposed multiplier receives and outputs the data with binary representation and uses only one-level carry-save adder (CSA) to avoid the carry propagation at…
MACS: A Highly Customizable Low-Latency Communication Architecture Abstract?Networks-on-chips (NoCs) are an increasingly popular communication infrastructure in single chip VLSI design for enhancing parallelism and system scalability. Processing elements (PEs) connect to a communication topology via NoC switches, which are responsible for runtime establishment and management of inter-PE communication channels. < final year projects > [numbers_sections…
Mining Health Examination Records – A Graph-based Approach Abstract?General health examination is an integral part of healthcare in many countries. Identifying the participants at risk is important for early warning and preventive intervention. The fundamental challenge of learning a classification model for risk prediction lies in the unlabeled data that constitutes the majority of the…
Mitigating Denial of Service Attacks in OLSR Protocol Using Fictitious Nodes Abstract?With the main focus of research in routing protocols for Mobile Ad-Hoc Networks (MANET) geared towards routing efficiency, the resulting protocols tend to be vulnerable to various attacks. Over the years, emphasis has also been placed on improving the security of these networks. <...
On Increasing the Slow-Fading Channel Diversity Using Block-Coded MIMO-OFDM With Reconfigurable Antennas Abstract?a new block coding scheme to increase the diversity gain of multiple-input?multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) sys-tems over slow-fading wireless channels. We assume that the an-tenna elements at the transmitter are reconfigurable and capable of independently changing the physical characteristics of their…
Personalized Influential Topic Search via Social Network Summarization Abstract?Social networks are a vital mechanism to disseminate information to friends and colleagues. In this work, we investigate an important problem – the personalized influential topic search, or PIT-Search in a social network: Given a keyword query qissued by a useruin a social network, a PIT-Search is…
Privacy Protection and Intrusion Avoidance for Cloudlet-based Medical Data Sharing Abstract?popularity of wearable devices, along with the development of clouds and cloudlet technology, there has been increasing need to provide better medical care. The processing chain of medical data mainly includes data collection, data storage an data sharing, etc. < final year projects > Video…
Read Bitline Sensing and Fast Local Write-Back Techniques in Hierarchical Bitline Architecture for Ultralow-Voltage SRAMs Abstract?Voltage scalable decoupled SRAMs operating at a subthreshold region have various challenges, such as deteriorated read bitline (RBL) swing resulting in read sensing failure and degraded cell stability due to the half-select write. This paper proposes an equalized bitline scheme…
