This paper introduces and discusses some recent advances in the field of information freshness for Internet of things (IoT) applications. Focusing on a setup in which a large number of transmitters share a common wireless channel to deliver updates to a common receiver, we tackle in particular the role played by random access policies based on variations of the basic ALOHA protocol, employed in most practical IoT systems. The fundamental trade-offs that emerge are discussed together with the enhancement achieved by a number of novel schemes tailored to optimize age of information. The article aims to trigger discussion and further research on a relevant yet still largely unexplored field, and highlights some important issues and challenges that have yet to be addressed.

The built environment is undergoing a significant evolution, enabled by the Internet of Things (IoT) concept. IoT offers some far-reaching opportunities with the help of cloud computing to exploit technological advances for the benefit of the users, society, and the environment. Technological advances in IoT makes it easier to monitor and manage environments around us. Also, increasing control over lighting/daylighting amount, fresh air ventilation rate, temperature, noise level and humidity level increase ...
Small Cells in the Forthcoming 5G/IoT: Traffic Modelling and Deployment Overview
Al-Turjman, Fadi; Ever, Enver; Zahmatkesh, Hadi (2019-01-01)
This paper provides an overview of the use of small cells (e.g., femtocells) in the Internet of Things (IoT) environments. As a result of rapid increase in the number of mobile connected devices such as smart-phones and tablets, the demand for data traffic is exponentially increasing. In order to satisfy mobile users' requests and meet the requirements of high data traffic, mobile operators have to increase the network capacities dramatically. One of the promising solutions for the network operators to impr...
Parallel decodable channel coding implemented on a MIMO testbed
Aktaş, Tuğcan; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2007)
This thesis considers the real-time implementation phases of a multiple-input multiple-output (MIMO) wireless communication system. The parts which are related to the implementation detail the blocks realized on a field programmable gate array (FPGA) board and define the connections between these blocks and typical radio frequency front-end modules assisting the wireless communication. Two sides of the implemented communication testbed are discussed separately as the transmitter and the receiver parts. In a...
Price-based data delivery framework for dynamic and pervasive IoT
Al-Turjman, Fadi (2017-12-01)
Recent ongoing research efforts are taking advantage of the emerging technologies which realize the Internet of Things (IoT) paradigm. However, the realization of an IoT framework is still facing many challenges in terms of QoS, resource management and pricing, in addition to the most pressing challenge which is attributed to the integration of the heterogeneous nodes and devices that compete to efficiently route their data. Routing data and inter-nodal communication in IoT has not been yet well investigate...
