An adaptive, energy-aware and distributed fault-tolerant topology-control algorithm for heterogeneous wireless sensor networks
(Elsevier BV, 2016)This paper introduces an adaptive, energy-aware and distributed fault-tolerant topology-control algorithm, namely the Adaptive Disjoint Path Vector (ADPV) algorithm, for heterogeneous wireless sensor networks. In this ... -
Algorithms for sink mobility in wireless sensor networks to improve network lifetime
(Bilkent University, 2008)A wireless sensor network (WSN) consists of hundreds or thousands of sensor nodes organized in an ad-hoc manner to achieve a predefined goal. Although WSNs have limitations in terms of memory and processor, the main ... -
Available bit rate traffic engineering in MPLS networks with flow-based multipath routing
(Institute of Electronics Information and Communication Engineers, 2004)In this paper, we propose a novel traffic engineering architecture for IP networks with MPLS backbones. In this architecture, two link-disjoint label switched paths, namely the primary and secondary paths, are established ... -
Breathing detection based on the topological features of IR sensor and accelerometer signals
(IEEE Computer Society, 2017)This paper describes a non-contact breathing detection system using a pyro-electric infrared (PIR) sensor and an accelerometer. The multi-sensor system can be used to detect the respiratory disorders. A PIR sensor is placed ... -
A comparative study of single-layer and multi-layer traffic engineering approaches on transparent optical networks
(2007)This paper comparatively studies single-layer and multi-layer traffic engineering strategies on an IP/MPLS/WDM network. These strategies are evaluated and compared in two different scenarios. In the first scenario, the ... -
Consensus as a Nash Equilibrium of a Dynamic Game
(Institute of Electrical and Electronics Engineers Inc., 2017)Consensus formation in a social network is modeled by a dynamic game of a prescribed duration played by members of the network. Each member independently minimizes a cost function that represents his/her motive. An integral ... -
Direct volume rendering of unstructured grids
(Pergamon Press, 2003)This paper investigates three categories of algorithms for direct volume rendering of unstructured grids, which are image-space, object-space, and hybrid methods. We propose three new algorithms. Cell Projection algorithm, ... -
Distributed joint flow-radio and channel assignment using partially overlapping channels in multi-radio wireless mesh networks
(Springer, 2016)Equipping mesh nodes with multiple radios that support multiple wireless channels is considered a promising solution to overcome the capacity limitation of single-radio wireless mesh networks. However, careful and intelligent ... -
An efficient virtual topology design and traffic engineering scheme for IP/WDM networks
(2007)We propose an online traffic engineering (TE) scheme for efficient routing of bandwidth guaranteed connections on a Multiprotocol label switching (MPLS)/wavelength division multiplexing (WDM) network with a traffic pattern ... -
Evolution of the Hofstadter butterfly in a tunable optical lattice
(American Physical Society, 2015)Recent advances in realizing artificial gauge fields on optical lattices promise experimental detection of topologically nontrivial energy spectra. Self-similar fractal energy structures generally known as Hofstadter ... -
Fault-tolerant irregular topology design method for network-on-chips
(Institute of Electrical and Electronics Engineers Inc., 2014)As the technology sizes of integrated circuits (ICs) scale down rapidly, current transistor densities on chips dramatically increase. While nanometer feature sizes allow denser chip designs in each technology generation, ... -
Fault-tolerant topology generation method for application-specific network-on-chips
(Institute of Electrical and Electronics Engineers, 2015)As the technology sizes of integrated circuits (ICs) scale down rapidly, current transistor densities on chips dramatically increase. While nanometer feature sizes allow denser chip designs in each technology generation, ... -
Graph aware caching policy for distributed graph stores
(Institute of Electrical and Electronics Engineers Inc., 2015)Graph stores are becoming increasingly popular among NOSQL applications seeking flexibility and heterogeneity in managing linked data. Conceptually and in practice, applications ranging from social networks, knowledge ... -
Land art on the border between topology and atopology
(Bilkent University, 2009)The purpose of this study is to discuss the Land Art movement from a topological and atopological perspective. In order to establish an extensive understanding of the matters of topology and atopology, Arkady Plotnitsky’s ... -
MaterialVis: material visualization tool using direct volume and surface rendering techniques
(Elsevier Inc., 2014)Visualization of the materials is an indispensable part of their structural analysis. We developed a visualization tool for amorphous as well as crystalline structures, called MaterialVis. Unlike the existing tools, ... -
New formulations for the hop-constrained minimum spanning tree problem via Sherali and Driscoll's tightened Miller-Tucker-Zemlin constraints
(2010)Given an undirected network with positive edge costs and a natural number p, the hop-constrained minimum spanning tree problem (HMST) is the problem of finding a spanning tree with minimum total cost such that each path ... -
Nonequilibrium fractional Hall response after a topological quench
(American Physical Society, 2016)We theoretically study the Hall response of a lattice system following a quench where the topology of a filled band is suddenly changed. In the limit where the physics is dominated by a single Dirac cone, we find that the ... -
On the Delay Margin for Consensus in Directed Networks of Anticipatory Agents
(Elsevier B.V., 2016)We consider a linear consensus problem involving a time delay that arises from predicting the future states of agents based on their past history. In case the agents are coupled in a connected and undirected network, the ... -

(2012)ZigBee is a recent wireless networking technology built on IEEE 802.15.4 standard and designed especially for low-data rate and low-duty cycle applications such as home and building automation and sensor networks. One of ... -
Reconstruction of the polarization distribution of the Rice-Mele model
