We consider a massive Internet of Things (IoT) scenario where indoor IoT devices access the network via optical wireless communication (OWC) systems that relay data backhaul radio frequency (RF) low-power wide-area (LP WAN). propose novel two-tier multi-rate Slotted ALOHA (SA) system model to design and analyse such hybrid OWC/RF networks. For particular setup, we present an in-depth numerical ...

Wireless mesh networks have the potential to provide ubiquitous high-speed Internet access at low costs. The good news is that initial deployments of WiFi meshes show the feasibility of providing ubiquitous Internet connectivity. However, their performance is far below the necessary and achievable limit. Moreover, users’ subscription in the existing meshes is dismal even though the technical ch...

In this paper, adaptive channel management approach fuzzy neural networks in heterogeneous wireless networks (ACM-FNN) is presented to efficient resource allocation, and admission control schemes are needed to guarantee quality-of-service (QoS) for differentiated services. The channel management in a two-tier such as micro cell or macro cell wireless networks. Effective reliability and efficien...
