Constraint Hubs Deployment for Efficient Machine-Type Communications [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2018
Massive Internet of Things (mIoT) is an important use case of 5G. The main challenge for mIoT is the huge amount of uplink traffic as it dramatically overloads the radio access network (RAN). To mitigate this shortcoming, a new RAN technology has been suggested, where small cells are used for interconnecting different devices to the network. The use of

Learning with finite memory for machine type communication [PDF]

open access: yes2016 Annual Conference on Information Science and Systems (CISS), 2016
Machine-type devices (MTDs) will lie at the heart of the Internet of Things (IoT) system. A key challenge in such a system is sharing network resources between small MTDs, which have limited memory and computational capabilities. In this paper, a novel learning \emph{with finite memory} framework is proposed to enable MTDs to effectively learn about ...

A Traffic Model for Machine-Type Communications Using Spatial Point Processes [PDF]

open access: yes, 2017
A source traffic model for machine-to-machine communications is presented in this paper. We consider a model in which devices operate in a regular mode until they are triggered into an alarm mode by an alarm event. The positions of devices and events are
