TL;DR: The networking scheme involves a two-tier cluster network based on IEEE 802.11ah, which can provide traffic isolation between the tiers and the security scheme guarantees the accuracy and availability of the collected information from the disaster area applying fingerprint features and data redundancy techniques.

TL;DR: Important medium access control (MAC) layer performance metrics of differentiated QoS IoT nodes in the IEEE 802.11ah RAW mechanism are evaluated to evaluate the feasibility of coexistence of priority and nonpriority traffic in IoT devices without degrading network performance.

TL;DR: An empirical investigation aimed at finding appropriate measures and establishing simple, yet usable and cost-effective models for estimation and control of object-oriented system projects, was undertaken on a set of objects implemented in a stable environment.

TL;DR: This work considers the IEEE 802.15.4 network in beacon enabled mode, and analyzes its performance under two duty cycle management algorithms, finding that both policies are capable of achieving almost 100% reliability and less than 1% utilization under a wide range of packet arrival rates and network size.

TL;DR: A detailed analysis of the operation of the MAC layer according to the 802.15.4 standard reveals a number of issues which may potentially become performance bottlenecks and thus lead to serious performance degradation, and suggests modifications of the coordinator function that allow the network to handle higher traffic loads and thus offer much improved performance to its clients.
