Massive machine-type communication (mMTC) access with integrated authentication [PDF]
2017 IEEE International Conference on Communications (ICC), 2017 We present a connection establishment protocol with integrated authentication, suited for Massive Machine-Type Communications (mMTC). The protocol is contention-based and its main feature is that a device contends with a unique signature that also enables the authentication of the device towards the network. The signatures are inspired by Bloom filters

Contention resolution queues for massive machine type communications in LTE [PDF]
2015 IEEE 26th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2015 In this paper, we address the challenge of high device density performing simultaneous transmissions by proposing and evaluating a solution to efficiently handle the initial access contention for highly dense LTE networks. We present the implementation of a tree-splitting algorithm in the access procedure of LTE, which is capable to cope with high ...

Random access for massive machine-type communications
CoRR, 2019 With an explosive development of the Internet-of-Things (IoT), the number of devices or machines (called users) connected to a base station is envisioned to reach tens of billions in the near future. In order to accommodate such a massive connectivity, random access schemes are deemed as an efficient method.

Compressive Massive Random Access for Massive Machine-Type Communications (mMTC)
2018 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2018 In future wireless networks, one fundamental challenge for massive machine-type communications (mMTC) lies in the reliable support of massive connectivity with low latency. Against this background, this paper proposes a compressive sensing (CS)-based massive random access scheme for mMTC by leveraging the inherent sporadic traffic, where both the ...
