impact of request aggregation on machine type Connection Establishment in lte advanced
Wireless Communications and Networking Conference, 2017Co-Authors: Mikhail Vilgelm, Wolfgang KellererAbstract:This paper presents a hierarchical cluster-based protocol for LTE Connection Establishment of a massive number of Machine Type User Equipments (mUEs). The protocol facilitates spatial reuse of random access channel resources. Our contributions are (i) modeling and analysis of the Connection request aggregation, and a study on its influence on the Connection from clusterhead to base station, and (ii) an accurate joint medium access model of a random access procedure within a finite-user cluster, considering the cross-impact and interrelation between aggregation and random access procedures. A byproduct of the joint analysis is an accurate finite-user model of random access without aggregation. The models are verified with the simulations and compared to the state-of-the-art. They allow accurate performance predictions, and provide insights on the dimensioning and resource allocation for clusters.

Massive machine-type communication (mMTC) access with integrated authentication
IEEE International Conference on Communications, 2017Co-Authors: Nuno K. Pratas, Cedomir Stefanovic, Sarath Pattathil, Predrag PopovskiAbstract: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 and are created based on the output of the MILENAGE authentication and encryption algorithm set, which is used in the authentication and security procedures in the LTE protocol family. We show that our method utilizes the system resources more efficiently, achieves lower latency of Connection Establishment for Poisson arrivals and allows a $87\%$ signalling overhead reduction. An important conclusion is that the mMTC traffic benefits profoundly from integration of security features into the Connection Establishment/access protocols, instead of addressing them post-hoc, which has been a common practice.

Random access for machine-type communication based on bloom filtering
2016 IEEE Global Communications Conference GLOBECOM 2016 - Proceedings, 2016Co-Authors: Nuno K. Pratas, Cedomir Stefanovic, German Corrales Madueño, Predrag PopovskiAbstract:We present a random access method inspired on Bloom filters that is suited for Machine-Type Communications (MTC). Each accessing device sends a \emph{signature} during the contention process. A signature is constructed using the Bloom filtering method and contains information on the device identity and the Connection Establishment cause. We instantiate the proposed method over the current LTE-A access protocol. However, the method is applicable to a more general class of random access protocols that use preambles or other reservation sequences, as expected to be the case in 5G systems. We show that our method utilizes the system resources more efficiently and achieves significantly lower Connection Establishment latency in case of synchronous arrivals, compared to the variant of the LTE-A access protocol that is optimized for MTC traffic. A dividend of the proposed method is that it allows the base station (BS) to acquire the device identity and the Connection Establishment cause already in the initial phase of the Connection Establishment, thereby enabling their differentiated treatment by the BS.
