Security and privacy in emerging networks: Part 1 [Guest Editorial]
(
IEEE
, 2015 , Article)
With the recent advancements in networking technologies, some new emerging networks are being implemented that have the potential to be deployed broadly and on a large scale in the near future. In the wired domain, these ...
An energy-efficient distributed clustering algorithm for heterogeneous WSNs
(
Springer International Publishing
, 2015 , Article)
Wireless sensor networks (WSNs) were envisaged to become the fabric of our environment and society. However, they are yet unable to surmount many operational challenges such as limited network lifetime, which strangle their ...
Optimal Determination of Respiratory Airflow Patterns for a General Multicompartment Lung Mechanics System with Nonlinear Resistance and Compliance Parameters
(
American Society of Mechanical Engineers (ASME)
, 2015 , Article)
In this paper, we develop a framework for determining optimal respiratory airflow patterns for a multicompartment lung mechanics system with nonlinear resistance and compliance parameters. First, a nonlinear multicompartment ...
An Attack-Resistant Trust Model Based on Multidimensional Trust Metrics in Underwater Acoustic Sensor Network
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
Underwater acoustic sensor networks (UASNs) have been widely used in many applications where a variable number of sensor nodes collaborate with each other to perform monitoring tasks. A trust model plays an important role ...
A Fatigue Measuring Protocol for Wireless Body Area Sensor Networks
(
Springer New York LLC
, 2015 , Article)
As players and soldiers preform strenuous exercises and do difficult and tiring duties, they are usually the common victims of muscular fatigue. Keeping this in mind, we propose FAtigue MEasurement (FAME) protocol for ...
Ionic Liquids in Bulk and at an Interface
(
John Wiley & Sons, Inc
, 2015 , Book chapter)
In the present chapter, we describe different types of investigation carried out by research groups based at CQE/IST/UTL and ITQB/UNL and their ramifications in terms of surface science. Most of the work is focused on the ...
Modelling the degradation of vibration characteristics of reinforced concrete beams due to flexural damage
(
John Wiley & Sons, Ltd.
, 2015 , Article)
This paper presents an improved crack model incorporating non-linearity of flexural damage in concrete to reproduce changes in vibration properties of cracked reinforced concrete beams. A reinforced concrete beam model ...
Maximizing Energy Efficiency in Multiple Access Channels by Exploiting Packet Dropping and Transmitter Buffering
(
IEEE
, 2015 , Article)
Quality of service (QoS) for a network is characterized in terms of various parameters specifying packet delay and loss tolerance requirements for the application. The unpredictable nature of the wireless channel demands ...
Implementation and Analysis of Reward Functions under Different Traffic Models for Distributed DSA Systems
(
IEEE
, 2015 , Article)
In this paper, we implement and analyze a resource allocation protocol for distributed dynamic spectrum allocation (DSA) systems. The DSA protocol is a learning-based protocol that allows secondary users (SU) to exploit ...
Beamforming OFDM Performance under Joint Phase Noise and I/Q Imbalance
(
IEEE
, 2015 , Article)
Phase noise (PHN) and in-phase/quadrature (I/Q) imbalance are two major RF impairments in direct-conversion wireless transceivers. Beamforming and orthogonal frequency division multiplexing (OFDM) schemes have been adopted ...
