Random and dedicated access in DVB-RCS2 for reliable delivery of IoT data

In this paper, we propose a realistic architecture for the integration between wireless sensor and satellite networks, covering technological issues from the access layer up to the transport and session layers, when uncorrelated sensor sources generate measurements' data. These data are multiplexed by a satellite gateway before being encapsulated and delivered through TCP/IP flows. This work aims at investigating the convenience, in terms of access delay and employed resources, in using the new random access methods based on successive interference cancellation, while guaranteeing the same throughput performance of the demand assignment multiple access systems. Moreover, this is the first work that provides a queue analysis of a satellite random access technique compared with dedicated access techniques with both short- and long-lived elastic connections.
