I'm a PhD student in GC University Faisalabad, Pakistan. I received my Master’s degree from COMSATS University Islamabad, Pakistan. I worked as Research Assistant in COMSATS University Islamabad during my graduate studies. My research interests are wireless channel modeling and characterization, V2V communication, massive MIMO systems/mmWave, backscatter communication, massive IoT and communication using large/reconfigureable intelligent surfaces.

In ongoing cellular generation, the selected radio spectrum (i.e., millimeter waves [mm-Wave]) is unable to achieve the required data rates. Future cellular generations need more data rate and link reliability to serve emerging intelligent applications of B5G and 6G (e.g., autonomous driving, virtual reality, etc.). To handle these limitations of ongoing cellular generation, the researchers are working on key factors to have a smart, high capacity and ultra-reliable propagation environment. To increase the data rate of the B5G and 6G network systems, the terahertz (THz) band is selected. However, to increase link reliability, the intelligent reflecting surfaces (IRSs) have a crucial impact on wireless network environments. Immense work has been done on the performance analysis of IRS-assisted wireless communication networks. This treatise imposes a comparison of such IRS-assisted THz communication systems, and future promising applications.

The massive machine type communications (mMTC) service category of 5G supports ultra-dense deployment of connected devices with low-power and low datarate requirements, and so it naturally supports internet-of-things (IoT) communications. Also, the ambient backscatter communications (BsC) holds potential for enabling energyconstrained IoT communications due to its extremely low power requirements. This work analyzes the downlink of a NOMA-enabled cellular system bundled with symbiotic radiobased mMTC. Closed-form expressions of the outage probability for the signal-to-interference and noise ratio (SINR) and the ergodic rate are derived for the symbiotic radio backscatter device as well as the primary cellular user. Several interesting use-cases of the proposed system model are discussed for future massive IoT and cell-free networks. The theoretical results presented are validated through numerical evaluations.

They’re entertaining, interesting, and demanding, and you can use them as learning tools to help the development of your children. Even easy puzzles need a certain degree of skill and commitment to complete. Once done, the effects are for people of all ages, but especially for children. This article provides the insight on how puzzles help children for cognitive development.
