Energy Efficient Uav Assisted Communication With Spectrum Optimization
ABSTRACT:
Cognitive radio (CR) is one of the new long-term communications technology developments taking place on radio receiver devices. Due to the Software Defined Radio (SDR) approach realization cognitive radio technology will be the next major step forward enabling more effective radio communications systems to be developed over the multi-access radio service providers. Multi-radio access technology (multi-RAT) can improve network capacity due to the data transmission by multiple RANs (radio access networks) simultaneously such as Wi-Fi LTE network topologies. ?In this concept, the network is considered a new CRN model in heterogeneous multiple PU, and the secondary spectrum model is overlaid below the Femto and microcell networks. The energy-efficient resource allocation (EERA) problem for CR users with multiple primary user networks overlapping coverage regions the concept proposes an equal power sensing algorithm-based search scheme to obtain an optimal solution in terms of the power and bandwidth. Various resource management processes are also implemented to deduce the network overloading over the cognitive base network topology.
