Typically, monolithic user mobility research developed unified ETSI MEC system reference architecture centers. considers as tool breaking applications into set loosely coupled components. It...

The sixth-generation cellular systems are expected to utilize the sub-terahertz frequency band covering 100-300 GHz. Due high path losses, coverage of such will be limited a few tens meters making them suitable for indoor environments. As compared outdoor deployments, usage is characterized by need operate over shorter distances using both line-of-sight (LoS) and in-reflection propagation paths. This potentially results not only in attenuation radio signal, but appearance diffraction...

Cognitive radio enabled social internet of things (CR-SIoT) can potentially revolutionize the existing networking paradigm by enabling heterogeneous IoT users to communicate socially like friends using limited spectrum.
