Massive Machine-Type Communications and Revival of ALOHA
نویسنده
چکیده
In this paper, we provide an overview of recent developments in the domain of Machine-Type Communications (MTC) for current and next-generation wireless cellular systems. We describe existing MTC standards and discuss in more detail the necessity of novel solutions for massive access of machinetype devices to the mobile cellular network. In particular, we focus on recent developments in the domain of ALOHA-based random access, known as Coded Slotted ALOHA (CSA). We review recent results that show CSA is capable of dramatically increasing the throughput of ALOHA-based schemes, both in single base-station and multi-base station scenarios, making CSA one of the suitable candidates for future MTC.

Performance Analysis of a Novel Hybrid S-ALOHA/TDMA Protocol for Beta Distributed Massive MTC Access
Simultaneous random access of massive machine type communications (MTC) devices are expected to cause congestion in the radio access network. Not only the performance of MTC, but the coexisting human to human (H2H) communications would also degrade dramatically without an appropriate medium access control (MAC) protocol. However, most existing solutions focus on the random access procedure with...
متن کاملFast Adaptive S-ALOHA Scheme for Event-driven M2M Communications (Journal version)
Supporting massive device transmission is challenging in Machine-to-Machine (M2M) communications. Particularly, in event-driven M2M communications, a large number of devices activate within a short period of time, which in turn causes high radio congestions and severe access delay. To address this issue, we propose a Fast Adaptive S-ALOHA (FASA) scheme for random access control of M2M communica...

The efficient support of the massive device transmission is challenging in Machine-to-Machine (M2M) communications. A large number of devices activate transmissions within a short period of time in M2M communications, which in turn cause high radio access congestions and severe wireless access medium delay. In this context, this work proposes a hybrid MAC approach, based on the well-known ALOHA...
متن کاملCode-Expanded Radio Access Protocol for M2M Communications
The random access methods used for support of Machine-to-Machine (M2M), also referred to as Machine-Type Communications (MTC), in current cellular standards are derivatives of traditional framed slotted ALOHA and therefore do not support high user loads efficiently. We propose an approach that is motivated by the random access method employed in LTE, which significantly increases the amount of ...
متن کاملEnhancing Contention Resolution ALOHA using Combining Techniques
Recently, random access protocols have acquired a new wave of interest, not only from the satellite communication community, but also from researchers active in fields like Internet of Things and machine-to-machine. Asynchronous (slotand frame-wise) ALOHA-like random access protocols, are very attractive for such applications, enabling low complexity transmitters and avoiding time synchronizati...
