“…In [8] it is shown through simplified analysis that SSA throughput is critically dependent on the demodulator signal-to-noise plus interference (SNIR) threshold. Results reported in [8] indicate that differently from SA, SSA shows a steep PLR increase with MAC load. Thus SSA can be operated with low PLR close to the peak of the throughput characteristic.…”

“…Additionally, SSA allows operating in a truly asynchronous mode, with no overhead for terminal burst synchronization. Furthermore, SSA throughput is enhanced by using low FEC coding rates [8] and low order modulations which is not the case for slotted RA schemes. However, the SSA Achilles' heel resides in its high sensitivity to multiple access carrier power unbalance.…”

“…The proposed return link multiple access scheme employs asynchronous spread spectrum Aloha (SSA) techniques [6,7] combined with low-rate forward error correction (FEC) [8] and downlink channel quality-based transmit on-off packet control at the user side. The proposed waveform for the return link is based on a modified version of the 3GPP Wideband Code Division Multiple Access (W-CDMA) Standard Random Access Channel (RACH) physical layer design [9].…”

The work presented here describes the key design drivers and performance of a high efficiency satellite mobile messaging system well adapted to the machine-to-machine communication services targeting, in particular, the vehicular market. It is shown that the proposed return link multiple access solution is providing a random access channel (RACH) aggregated spectral efficiency around 2 bit/s/Hz in the presence of power unbalance with reliable packet delivery over typical land mobile satellite (LMS) channels.

SUMMARY This paper surveys the most popular random access (RA), demand assignment (DA), and hybrids schemes for satellite broadband access networks. In addition, we present some recent research results that we obtained when a reliable transmission control protocol, that is, TCP, is coupled with the most promising RA methods foreseen in the second generation of Digital Video Broadcasting–Return Channel via Satellite standard. In fact, the necessity to support a wider range of IP‐based traffic, as in the case of either Supervisory Control And Data Acquisition systems or Machine‐to‐Machine communications, fosters the introduction of RA schemes for information transport able to cope with large network sizes and low duty cycle bursty traffic with frequent inactivity periods on the return link. As an indication of future research aspects, we also offer, in the Conclusions section, a list of items to be investigated so that the satellite can become an integral part of the Future Internet.
