Multi-resource arbitration is used where interchangeable resources need to be assigned among a number of client users. An efficient arbiter is thus critical to manage these shared resources. There has been only limited prior research on efficient asynchronous solutions, which have mainly focused on serial approaches. In this paper, a new high-throughput multi-resource arbiter is proposed, based on...
Single-cell genomics is used to advance our understanding of diseases such as cancer. Microfluidic solutions have recently been developed to classify cell types or perform single-cell biochemical analysis on pre-isolated types of cells. However, new techniques are needed to efficiently classify cells and conduct biochemical experiments on multiple cell types concurrently. System integration and design...
The real-time monitoring of status parameters, such as cell voltage and state of charge (SOC), is an important guarantee of the safety operation of the battery energy storage system (BESS). And the two-level architecture of hardware system which includes several battery management units (BMU) and the central management unit (CMU) is designed with the communication protocol and data conversion algorithm...
Emerging non-volatile memory technology Spin Transfer Torque Random Access Memory (STT-RAM) is a good candidate for the Last Level Cache (LLC) on account of high density, good scalability and low power consumption. However, expensive write operation reduces their chances as a replacement of SRAM. To handle these expensive write operations, an STT-RAM/SRAM hybrid cache architecture is proposed that...
The massive admiration of cellular devices has stimulated a flourishing growth of high data rate wireless services, which has sparked an insisting need for more efficient spectrum usage as well as reduced power consumption. This has given rise to Device-to-Device (D2D) communication, which offloads the relaying burden of the base station to direct links between the users. Recent studies have shown...
Through massive deployment of additional small cell infrastructure, Dense Small cell Networks (DSNs) are expected to help meet the foreseen increase in traffic demand on cellular networks. Performance assessment of architectural and protocol solutions tailored to DSNs will require system and network level simulators that can appropriately model the complex interference environment found in those networks...
Future heterogeneous networks (HetNets) are going to consist of cellular macro cell base stations (macro-BSs) and various types of small cell base stations (SC-BS), each operating in microwave and/or millimeter bands. Cell discovery of mm-wave SC-BSs is a challenging issue because of the limited communication range. In this paper, a location-based cell selection scheme that takes into account the...
In networking, mainly for routers, firewalls, access control lists, etc., packet classification lies in the critical data path as it has to act upon each and every packet at wire-speed. Another critical issue associated with packet classification is efficient representation of rules with range(s) which takes multiple TCAM rule entries in the rule table called range expansion. In addition, range expansion...
A heterogenous network is considered where the base stations (BSs), small base stations (SBSs) and users are distributed according to independent Poisson point processes (PPPs). We let the SBS nodes to posses high storage capacity and are assumed to form a distributed caching network. Popular data files are stored in the local cache of SBS, so that users can download the desired files from one of...
Computer-aided design (CAD), in its quest to facilitate new design revolutions, is again on the brink of changing its scope. Following both historical and recent technological and application trends, one can identify several emerging research and development directions in which CAD approaches and techniques may have major impacts. Among them, due to the potential to fundamentally alter everyday life...
This paper proposes a hardware architecture to generate harmonized music, which is composed by melodic intervals determined from the association of cellular automata in accordance to standard MIDI protocol. The implementation of the architecture is implemented in FPGA aiming at designing an alternative efficient tool for the study and research related to the field of random music. To this end, the...
In an effort to support resource reservation signalling IETF introduced the Next Step In Signalling (NSIS) suite as a generic framework. However, it causes significant overhead on the network and is not well-suited for mobile users. This paper presents a new mechanism to reduce the NSIS signalling overhead and resource reservation latency imposed by the node's mobility in mobile networks. The proposed...
Vehicular networking, both vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I), is an increasingly important usage scenario for future mobile Internet services. Radio technologies such as 3G/4G and WAVE/802.11p now enable vehicles to communicate with each other and connect to the Internet, but there is still the lack of a unifying network protocol architecture for delivery of services across...
3rd Generation Partnership Project (3GPP) proposes relay architecture to extend the coverage and enhance the system capacity of Long Term Evolution Advanced (LTE-A). In the relay architecture, the header compression mechanism called RObust Header Compression (ROHC) is introduced to eliminate packet overhead and provide better spectral efficiency for IP packet transmission over the radio. However,...
This article consists of a collection of slides from the author's conference presentation on high performance and efficient single-chip small cell base station communications. Some of the specific topics discussed include: a basic overview of base station processing; small cell capabilities for heterogeneous radio access networkgs; small cell design based on OCTEON Fusion (Cavium); the architecture...
Mobility in wireless sensor networks is an element which directly influences the network performance. Indeed, with an architecture based on the IP stack, a mobile node has to maintain connectivity with other sensors, also allowing connectivity to the Internet. Among IPv6 based protocols proposed for mobility management, we find Mobile IPv6 (MIPv6), Hierarchical Mobile IPv6 (HMIPv6) and Proxy Mobile...
Application-level protocol specifications are helpful for network security management, including intrusion detection and intrusion prevention which rely on monitoring technologies such as deep packet inspection. Moreover, detailed knowledge of protocol specifications is also an effective way of detecting malicious code. However, current methods for obtaining unknown and proprietary protocol message...
Electroporation uses short, pulsed electric fields to induce a cellular transmembrane potential that results in increased cellular permeability. When performed irreversibly, it results in cell death while leaving the extracellular matrix and other sensitive structures intact. These electric fields result in thermal effects to the affected tissues due to resistive heating. We measure this heating extent...
Agent-Based Social Simulations have been largely used to study social phenomena. These kinds of simulations are related to reproduce real societies (e.g. social behaviors) using a bottom-up strategy. In classical social simulations, plausible macro-behaviors are only obtained if the social scientists input every features, components and relationships. Alternatively, modern agent-based modeling tools...
The focus of this paper is to present an architecture for the seamless integration of devices in Small and Medium Enterprises (SMEs). Our proposal intends to cover any device, regardless of manufacturer or technology level. In this scenario, small lot sizes and the fast adaptability of the production environment is more important than short cycle times. Moreover, the ability to incorporate new devices...
