Next Generation M2M Cellular Networks: Challenges and Practical Considerations
Abdelmohsen Ali, Walaa Hamouda, Murat Uysal
In this article, we present the major challenges of future machine-to-machine (M2M) cellular networks such as spectrum scarcity problem, support for low-power, low-cost, and numero…
Spectrum Monitoring Using Energy Ratio Algorithm For OFDM-Based Cognitive Radio Networks
Abdelmohsen Ali, Walaa Hamouda
This paper presents a spectrum monitoring algorithm for Orthogonal Frequency Division Multiplexing (OFDM) based cognitive radios by which the primary user reappearance can be detec…
Low Power Wideband Sensing for One-Bit Quantized Cognitive Radio Systems
Abdelmohsen Ali, Walaa Hamouda
We proposes an ultra low power wideband spectrum sensing architecture by utilizing a one-bit quantization at the cognitive radio (CR) receiver. The impact of this aggressive quanti…
A Subset Selection Algorithm for Wireless Sensor Networks
Seyed Hamed Mousavi, Javad Haghighat, Walaa Hamouda +1
One of the main challenges facing wireless sensor networks (WSNs) is the limited power resources available at small sensor nodes. It is therefore desired to reduce the power consum…
