A color-based face tracking algorithm for enhancing interaction with mobile devices
(Springer, 2010-05)A color-based face tracking algorithm is proposed to be used as a human-computer interaction tool on mobile devices. The solution provides a natural means of interaction enabling a motion parallax effect in applications. ... -
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 ... -
Identification of insect damaged wheat kernels using transmittance images
(2004)We used transmittance images and different learning algorithms to classify insect damaged and un-damaged wheat kernels. Using the histogram of the pixels of the wheat images as the feature, and the linear model as the ... -
Integrating social features into mobile local search
(Elsevier Inc., 2016)As availability of Internet access on mobile devices develops year after year, users have been able to make use of search services while on the go. Location information on these devices has enabled mobile users to use local ... -
Interference analysis of fixed terrestrial microwave LOS/NLOS radio links
(Institute of Electrical and Electronics Engineers Inc., 2015)In this study, interference modelling is investigated for fixed terrestrial microwave LOS (line-of-sight)/ NLOS (transhorizon) radio links operating in NATO Band 3+ (1350-2690 MHz) and NATO Band 4 (4400-5000 MHz) frequency ... -
Joint routing, gateway selection, scheduling and power management optimization in wireless mesh networks
(Institute of Industrial Engineers, 2012-05)The third generation (3G) wireless communications technology delivers user traffic in a single step to the wired network via base station; therefore it requires all base stations to be connected to the wired network. On ... -
On the analysis of expected distance between sensor nodes and the base station in randomly deployed WSNs
(Springer Verlag, 2014)In this study, we focus on the analytical derivation of the expected distance between all sensor nodes and the base station (i.e., E[dtoBS]) in a randomly deployed WSN. Although similar derivations appear in the related ... -
Performance of edge windowing for OFDM under non-linear power amplifier effects
(Institute of Electrical and Electronics Engineers Inc., 2017)Edge windowing is a windowing technique for Orthogonal Frequency Division Multiplexing (OFDM) signals based on the idea of using shorter cyclic prefix (CP) and longer window lengths at the edge subcarriers while keeping ... -
PETAL: a fully distributed location service for wireless ad hoc networks
(Academic Press, 2017)Location service is an essential prerequisite for mobile wireless ad hoc networks (MANETs) in which the underlying routing protocol leverages physical location information of sender and receiver nodes. Fulfillment of this ... -
Reducing Router-Crossings in a Mobile Intranet
(Springer, 1998)Current general purpose mobility solutions like Mobile-IP involve multiple router-crossings even when the mobile host moves within an intranet from one subnet of a router to another. An environment consisting of a large ... -
Sequential churn prediction and analysis of cellular network users-A multi-class, multi-label perspective
(Institute of Electrical and Electronics Engineers Inc., 2017)We investigate the problem of churn detection and prediction using sequential cellular network data. We introduce a cleaning and preprocessing of the dataset that makes it suitable for the analysis. We draw a comparison ... -
Tree-based channel assignment schemes for multi-channel wireless sensor networks
(John Wiley & Sons Ltd., 2016)Many sensor node platforms used for establishing wireless sensor networks (WSNs) can support multiple radio channels for wireless communication. Therefore, rather than using a single radio channel for whole network, multiple ... -
Vision-based single-stroke character recognition for wearable computing
(IEEE, 2001)Particularly when compared to traditional tools such as a keyboard or mouse, wearable computing data entry tools offer increased mobility and flexibility. Such tools include touch screens, hand gesture and facial expression ... -
WiSAP: a wireless personal access network for handheld computing devices
(Institute of Electrical and Electronics Engineers, 1998)New short-range wireless communication technologies would enable environment-aware, mobile, personal area networks. These new technologies will serve as enablers for ubiquitous, low-cost, low-complexity, small-sized ... -
A zone-based shared-tree multicast protocol for mobile ad hoc networks
(2003)This paper proposes a new multicast protocol for mobile ad hoc networks (MANETs). The proposed protocol, Shared-Tree MZR, is a shared tree variant of the Multicast Routing Protocol based on Zone Routing (MZR). The concept ...
