Feedback Implosion Suppression Algorithm for Reliable Multicast Data Transmission over Geostationary Satellite Networks

Abstract

In this paper, we propose a feedback implosion algorithm delays the segment until the probability of suppression (FIS) algorithm that reduces the volume of feedback retransmission for the segment is less than a specified traffic from receivers in a multicast group over a geostationary upperbound value. The paper shows that the scheduling policy satellite network. The system considered in this paper includes a improves the total session delay by reducing the number of reliable multicast transport protocol that operates on top of a segments retransmitted and by exploitation of reported CSI channel-aware scheduler (CAS) scheduler at the M\AC layer. The periodic CSI updates become collision problem is avoided altogether and, (ii) we include a the input to the scheduler to make a decision to transmit a "update age" parameter for fair treatment of receivers that particular segment in the current timeslot.

Multicast Link Adaptation in Reliable Transmission Over Geostationary Satellite Networks

“…All terminals are considered within a common propagation type; each terminal is subject to independent and individually distributed (i.i.d) LOS and fading durations. Each terminal is capable of measuring its E b /N o every 10 ms and decides to send the E b /N o when significant changes are observed, as proposed in Change Detection (CD) mechanism described in [13]. Specifically, based on the uplink access scheme and the CD mechanism, the terminal that observes a high enough variation in E b /N o fluctuation will ask for a capacity request by sending a Status Signalling Data Unit (SDU) message through a contention slot.…”

A feedback suppression algorithm for reliable satellite multicast based on spatial–temporal prediction of the satellite channel

“…In [9], a feedback suppression algorithm using the multiple subset sum formulation is presented, which reduces the number of uplink timeslots reserved for feedback transmission. Finally, in [10,11], feedback suppression algorithms for reliable multicast data transmission over satellite are proposed exploiting the correlation of satellite channel variations [12].…”

Throughput and Delay Analysis in Video Streaming Over Block-Fading Channels

“…Some streaming protocols, such as HTTP Live Streaming, allow rate adaption among only a limited number of available rates.2 With this we implicitly assume a slow varying channel, for example, a mobile terminal moving at pedestrian speed 3. In the downlink channel with many receiving terminals, acquisition of CSIT is not viable, since this requires the transmission of an extensive amount of information which may result in the feedback implosion problem[15].
