The cognitive radio technology can provide dynamic spectrum access and improve the efficiency of spectrum utilization. Spectrum sensing is one of the key technologies of cognitive radio networks. The spectrum sensing performance of cognitive radio networks will be greatly reduced in the low SNR environment, especially when using energy detection. Due to the monostable stochastic resonance syste...

Wireless Sensor Networks (WSNs) require an efficient intrusion detection scheme to identify malicious attackers. Traditional detection schemes are not well suited for WSNs due to their higher false detection rate. In this paper, we propose a novel intrusion detection scheme based on the energy prediction in cluster-based WSNs (EPIDS). The main contribution of EPIDS is to detect attackers by com...

We discuss in some detail the production of extremely high energy (EHE) neutrinos with energies above 1018 eV. The most certain process for producing such neutrinos results from photopion production by EHE cosmic rays in the cosmic background photon Ðeld. However, using assumptions for the EHE cosmic-ray source evolution that are consistent with results from the deep QSO survey in the radio and...

The ongoing convergence of Industrial Control Systems (ICSs) with the Internet introduces many challenges from security perspective. Particularly, the smart energy grid as large ICS and critical infrastructure, requires especial protection as the consequences of its failure can be severe. However, even a careful system design cannot prevent all attacks in advance. For this reason, the smart gri...

Here in this paper A MAC layer level congestion detection mechanism has been proposed. The proposed model aims to deliver an energy efficient mechanism to quantify the degree of congestion at victim node with maximal accuracy. This congestion detection mechanism is integrated with a Two-Step Cross Layer Congestion Control Routing Protocol. The proposed model involves controlling of congestion i...

Renewable energy sources are gaining high prominence in today’s world. However, these sources do not supply energy throughout the year and hence efficiency is required when extracting energy from them. Wind energy is a recently developing area of common interest. Efficiency of a wind turbine is however, very low. Hence, detection of fault in the system becomes very essential so as to increase t...
