The introduction of cellphones with poor receiver sensitivity, known as dirty devices, to the Code Division Multiple Access (CDMA) cellular network results in a reduction in cell edge coverage, degraded capacity, and higher drop-call rates. This poor network performance has a negative impact on customer experience and satisfaction, which may result in increased churn for…

Implementation of NB PHY transceiver of IEEE 802.15.6 WBAN on FPGA
This paper presents the hardware implementation of 2.4 GHz Narrowband Physical Layer for Wireless Body Area Network (WBAN) based on IEEE 802.15.6-2012 standard. Major building blocks of PHY transceiver such as CRC, spreader, interleaver and scrambler were individually designed and integrated. To avoid the inherent limitation of the data transmission and to achieve higher reliability…
BYOC: Bring Your Own Control a new concept to monetize SDN’s openness
Software Defined Networking (SDN) is supposed to bring flexibility, dynamicity and automation to today’s network through a logically centralized network controller. We argue that reaching SDN’s full capacities requires however the development of standardized programming capabilities on its top. In this paper we introduce “Bring Your Own Control” (BYOC) as a new concept providing a…
Distributed Secret Dissemination Across a Network
Shamir’s (n; k) threshold secret sharing is an important component of several cryptographic protocols, such as those for secure multiparty-computation and key management. These protocols typically assume the presence of direct communication links from the dealer to all participants, in which case the dealer can directly pass the shares of the secret to each participant.…
A Novel Computational Model for Non-linear Divisible Loads on a Linear Network
This work investigates the problem of a non-linear divisible load distribution on a homogeneous linear network. A novel computational model of non-linear loads that includes complete steps for processing them, is proposed. This model solves the problem of the classical model, whose performance degrades by separating the load. This work also presents an algorithm S…
Global Exponential Stability for Discrete-Time Networks With Applications to Traffic Networks
This paper provides sufficient conditions for global asymptotic stability and global exponential stability, which can be applied to nonlinear, large-scale, uncertain discrete-time networks. The conditions are derived by means of vector Lyapunov functions. The obtained results are applied to traffic networks for the derivation of sufficient conditions for global exponential stability of the uncongested equilibrium…
Optimal Approach for Reliability Assessment in Radial Distribution Networks
This paper proposes a new methodology for the evaluation of reliability in radial distribution networks through the identification of new investments in this kind of networks, in order to reduce the repair time and the failure rate, which leads to a reduction of the forced outage rate and, consequently, to an increase of reliability. The…
Sherlock Is Around: Detecting Network Failures with Local Evidence Fusion
Traditional approaches for wireless sensor network diagnosis are mainly sink-based. They actively collect global evidences from sensor nodes to the sink so as to conduct centralized analysis at the powerful back-end. On the one hand, long distance proactive information retrieval incurs huge transmission overhead; On the other hand, due to the coupling effect between diagnosis…
Multi-valued Neural Network Trained by Differential Evolution for Synthesizing Multiple-Valued Functions
We consider the problem of synthesizing multiple valued logic (MVL) functions by neural networks. A differential evolution algorithm is proposed to train the learnable multiple valued logic network. The optimum window and biasing parameters to be chosen for convergence are derived. Experiments performed on benchmark problems demonstrate the convergence and robustness of the network. Preliminary…
10.2 An FSK plastic waveguide communication link in 40nm CMOS
Technology scaling has enabled RF-CMOS circuits that operate in the millimeter-wave frequency range (30 to 300GHz) where large bandwidths are available. These bandwidths can be exploited to increase data-rates of wireless communication links. Unfortunately, free-space path loss (FSPL) limits the operating distance of wireless systems at these frequencies. A 5-meter link at 120GHz has an FSPL as…
