2020 ComNet: Energy and Spectral Efficient Scheduling for Heterogeneous IoT Sensor Nodes

C. S. Ferdowsy, Z. Bouida, and Mohamed Ibnkahla   With adaptive transmission, the throughput and power can be adapted to the channel conditions, which leads to a variable amount of energy consumption for the Internet of Things (IoT) sensor nodes. Considering an IoT network with heterogeneous sensor nodes in terms of their battery levels,... More

IEEE Transactions on Cognitive Communications and Networking: Enhanced Multiband Multiuser Cooperative Spectrum Sensing for Distributed CRNs

Anastassia Gharib, Waleed Ejaz, and Mohamed Ibnkahla   Multi-band cooperative spectrum sensing (CSS) can provide opportunistic spectrum access to secondary users (SUs) in cognitive radio networks (CRNs). In multi-band CSS, the sensing task is divided among SUs based on their capability, residual energy, channel conditions, etc. However, SUs'... More
