“…This redundancy permits the receiver to detect and correct erroneous packets. The FEC has effects on the measurements of several parameters, namely downlink and uplink message size, which can increase Round-Trip Time, as illustrated in [59].The following Fig. 4 illustrates the working principle of the FEC.…”

We expose a complete survey of error-correcting codes (ECC) for digital video broadcasting (DVB) to support information protection. This survey discusses the specific application of the adaptive ECC feature for terrestrial/satellite/handheld and cable of the first, second, and third generations. We provide and review an ECC technique overview on DVB standard with their technical transmission specifications. The critical contribution of this paper is to clarify the differences among different ECC technologies using in the three generations of DVB. The survey also provides future directions for the technology trend of ECC for DVB.

“…While in [20], the effect of the Downlink and Uplink message size on round trip time has been experimentally shown. This effect is treated with and without forwarding Error Correction (FEC) between a Supervisory Control and Data Acquisition (SCADA) center and a destination RTU (Remote Terminal Units).…”

“…It should be noted that the ACK settings need supplemental bandwidth for retransmission of lost or corrupted frames [20]. The transmitting packet sizes are not necessarily fixed; they can have variable sizes, depending on the type of network and its protocol.…”

This study presents a new practical measurement method for analyzing narrowband wireless mesh networks (NWMNs) application performance. It investigates a scenario for packet transmissions in NWMNs, leveraging wireless interconnection between two devices. It analyzes the effect of message size and channel spacing on the resulting bitrate, forwarding time and modulation rate through experimental results. We transmit a single packet for one hop, exploiting a versatile radio modem with very-high-frequency radios operating in the bridging or routing modes. The measurement results obtained, with the mentioned critical operating parameters, provide a quicker and clearer idea as well as conclusive evidence for overall network performance.

“…In particular, in such scenarios, the various constraints on the signal propagation parameters lead to varying modulation rates. In a multi-hop mesh network, the downlink and uplink message lengths influence the round trip time (RTT) [18] and end-to-end (E2E) testing process. Complex modulation schemes [19] can be used to improve the spectral efficiency in several applications with a limited frequency spectrum.…”

In this study, a narrowband (NB) internet of things (IoT) medical device (MD) wireless communication system was established, in which a multi-hop source to the MD network shared the downlink and uplink resources to probe and control the MDs of hospital patients. A multicast data packet was distributed over the multi-hop MD networks, and a random linear network coding approach was applied in the source instead of the intermediate nodes. We evaluated the MD probe cycle between a master station and remote terminal units, which were connected with several critical devices in a medical room. Furthermore, an accelerated end-to-end (E2E) probing protocol was established in the wireless mesh network to minimize the probing cycle of the health devices. In particular, a faster protocol was developed to address the probe and control subproblem. The proposed approach could assist in realizing the accelerated E2E probing for NB-IoT MDs, reducing the number of retransmissions, recovering lost packets, and providing a prompt overview of the medical network performance, based on several basic parameters. Furthermore, in a comparative study of the contemporary probing cycle techniques, the proposed protocol notably outperformed several widely used protocols, with the improvements typically exceeding 71% and 60%, respectively.
