This paper presents a speaker identification algorithm using the deep neural network (DNN) as the classifier to learn the features of the voiceprints represented by spectrogram. The collected speech signals are pre-emphasized, windowed, divided into some chunks, then calculated to obtain the magnitude of the frequency spectrum, which creates the spectrograms. The […]

Many Wireless Sensor Network (WSN) applications operate autonomously in unreliable or inaccessible environments, precluding maintenance or human intervention. Redundant deployment schemes are usually considered in this scenario, making the network resilient to failure and environmental changes. Furthermore, sleep-scheduling techniques can also be applied, enabling redundant nodes to turn off their radios, while active nodes […]
A sleep-scheduling scheme for enhancing QoS and network coverage in IEEE 802.15.4 WSN
Translating behavioral information learned from analysis of a botnet’s software in controlled environments, to a model of how the botnet behaves in the wild is complicated by the fact that controlled environments do not account for a wide variety of user behavior, and that machines are not associated one-to-one with […]
Visualizing and Modeling the Scanning Behavior of the Conficker Botnet in the Presence of User and Network Activity
This paper presents an energy management approach for a hybrid energy system comprised of a photovoltaic (PV) array and a polymer electrolyte membrane fuel cell (PEMFC). A single storage device, i.e., a Li-ion battery module, is used in the proposed structure. Linear proportional-integral (PI) and nonlinear flatness-based controllers for dc […]
DC Bus Stabilization of Li-Ion Battery Based Energy Storage for a Hydrogen/Solar Power Plant for Autonomous Network Applications
In this mobile-centric era, users expect ubiquitous data access at low cost to an ever increasing range of applications requiring high data connection speeds. A positive solution is the use of Wireless MeshNetworks (WMN) as they enable data access over a relatively large area at a modest cost and are relatively […]
Link quality-aware overlay for video delivery over wireless mesh networks
The Internet is radically changing the field of networking. A wide variety of technologies, protocols and internetworking techniques are now available and continuously changing with the rapid developments in the Internet scenario. For example, whereas ATM was heretofore viewed as the solution for allnetworking problems, today increasingly there is a debate whether […]
An overview of off-the-shelf tools and their applications to telecom and enterprise networking
Cellular STEM (Science, Technology, Engineering, and Mathematics) is a system conceived to interface computational/ visualization engines to SMS/MMS messaging for the purpose of enhancing STEM Education. The system allows users to send processing request to a computational/visualization engine (e.g. MATLAB, Octave) via SMS or MMS and receive the processed data […]
Cellular STEM: Promoting Interest in Science, Technology, Engineering, and Math Education Using Cellular Messaging, Cloud Computing, and Web-Based Social Networks
Wireless Sensor Networks (WSN’s) is one of the most leading technology around the globe which make it possible to assemble the embedded systems of wallet size with the similar proficiency of a Personal Computer. It consists of self-governing battery powered devices known as nodes which act as a transducer. The nodes are […]
An algorithm to minimize energy consumption using nature-inspired technique in wireless sensor network
Biometric systems are a part and parcel of everyone’s lives these days. However, with the increase in their use, the security risks associated with them have equally increased. Hence, there is an increased need to develop systems which use biometrics efficiently and ensure the authentication is integral and effective. This paper aims […]
A Generic Framework for EEG-Based Biometric Authentication
Just as Internet connectivity has enabled intuitive information sharing and interaction through the Web, so the Internet of Things might be the basis for the Web of Things, enabling equally simple interaction among devices, systems, users, and applications.
