Machine-to-Machine (M2M) communications are expected to be one of the major drivers of future cellular networks, due to a plethora of services provided to operators and consumers. This leads to an explosively growth of simultaneous M2M arrivals, and then a bursty random access attempts that causes a severe random access congestion in addition to terminals' synchronization issues. In this paper, we...
The Internet of Things (IoT) and particularly Machine-to-Machine (M2M) communications are considered as major enablers for future smart cities' initiatives. While offering a wide range of applications and services, supporting such devices constitutes, however, one of the most important challenges to be faced by Network Operators (NO). Indeed, the expected huge number of devices requesting to connect...
Machine Type Communications (MTC) come up with substantial revenue growth for Mobile Network Operators (MNO), but they represent at the same time the most important challenge they are facing. In fact, a massive number of MTC devices performs simultaneously the Random Access (RA), which causes severe congestion and reduces the RA success probability. To control the Radio Access Network (RAN) overload...
