Structural balance and opinion separation in trust–mistrust social networks
Structural balance theory has been developed in sociology and psychology to explain how interacting agents, e.g., countries, political parties, opinionated individuals, with mixed trust and mistrust relationships evolve into polarized camps. Recent results have shown that structural balance is necessary for polarization in networks with fixed, strongly connected neighbor relationships when the opinion dynamics are…
A New Pan-Sharpening Method With Deep Neural Networks
A deep neural network (DNN)-based new pansharpening method for the remote sensing image fusion problem is proposed in this letter. Research on representation learning suggests that the DNN can effectively model complex relationships between variables via the composition of several levels of nonlinearity. Inspired by this observation, a modified sparse denoising autoencoder (MSDA) algorithm is…
Directivity Estimations for Short Dipole Antenna Arrays Using Radial Basis Function Neural Networks
The role of directivity is very important in the operation of an array as it gives a measure of the effectiveness of the array in pointing the radiations in a specific direction. Traditional methods used for the computation of directivity are although effective but may be time consuming. Artificial neural networks (ANNs) do not require…
A survey on distributed techniques for detection of node clones in Wireless Sensor Networks
Wireless Sensor Networks consists of sensor nodes which are placed in harsh and hostile surrounding where an adversary may capture the nodes, replicate them and use it for its own purpose. If the clone nodes remain undetected, it can disrupt the network functions making it vulnerable to attacks. Hence false data can be injected or…
Energy Efficiency Analysis of Cooperative Jamming in Cognitive Radio Networks with Secrecy Constraints
We investigate energy-efficient cooperation for se- crecy in cognitive radio networks. In particular, we consider a four-node cognitive scenario where the secondary receiver is treated as a potential eavesdropper with respect to the primary transmission. The cognitive transmitter should ensure that the primary message is not leaked to the secondary user by using cooperative jamming.…
Semi-Persistent RRC Protocol for Machine-Type Communication Devices in LTE Networks
In this paper, we investigate the design of a radio resource control (RRC) protocol in the framework of long-term evolution (LTE) of the 3rd Generation Partnership Project regarding provision of low cost/complexity and low energy consumption machine-type communication (MTC), which is an enabling technology for the emerging paradigm of the Internet of Things. Due to the nature…
LED Based Indoor Visible Light Communications: State of the Art
Visible Light Communication (VLC) is an emerging eld in Optical Wireless Com- munication (OWC) which utilizes the superior modulation bandwidth of Light Emitting Diodes (LEDs) to transmit data. In modern day communication systems, the most pop- ular frequency band is Radio Frequency (RF) mainly due to little interference and good coverage. However, the rapidly dwindling RF spectrum along with…
Measurements on Rogowski coils as coupling elements for power line communication in traction lithium-ion batteries
We propose Rogowski coils as coupling elements for Power Line Communication (PLC) in lithium-ion batteries for electric and hybrid vehicles. Current battery management systems use standard CAN busses for the communication between the battery control unit (BCU) and battery modules, which comprise lithium-ion cells. In contrast, in next-generation batteries the BCU should communicate with each lithium-ion cell in a…
LMMSE equalized DCSK communication system over a multipath fading channel with AWGN noise
The advances in the development of chaos based communication system suggests that chaos shift keying (CSK) and its variant Differential CSK (DCSK) are one of the most promising candidates for practical implementation. In this paper a DCSK communication system incorporating a non coherent approach of demodulation based on a correlation detector is considered over a…
