Reliable Multicast Transport by Satellite: A Hybrid Satellite/Terrestrial Solution with Erasure Codes
نویسندگان
چکیده
Geostationary satellites are an efficient way to provide a large scale multipoint communication service. In the context of reliable multicast communications, a new hybrid satellite/terrestrial approach is proposed. It aims at reducing the overall communication cost using satellite broadcasting only when enough receivers are present, and terrestrial transmissions otherwise. This approach has been statistically evaluated for a particular cost function and appears to be advantageous. Then since the hybrid approach relies on Forward Error Correction, several practical aspects of MDS and LDPC codes are investigated in order to determine impact of code selection.

Group Size Estimation for Hybrid Satellite/Terrestrial Reliable Multicast
This paper addresses the problem of group size estimation for hybrid satellite/terrestrial multipoint communications. Estimators based on the maximum likelihood principle are investigated. These estimators assume that a Nack suppression mechanism is implemented at transport layer. The performance of these estimators is studied theoretically and via simulations. The integration of an appropriate...
متن کاملEfficient planning of satellite-terrestrial hybrid networks for multicast applications
As the satellite technology will be one of the main components of the Next Generation Internet (NGI), a naturally occurring question concerns the feasibility of providing an efficient satellite-based Internet access. In this paper, we are interested in the problem of the planning of satellite-terrestrial hybrid networks for the multicast transfer. We first develop an architectural model for suc...
متن کاملRedundant codes in hybrid networks
Hybrid networks consisting of satellite links and mobile ad hoc networks present a series of challenges due to different packet-loss patterns, delay, and, usually, scarce available bandwidth. In this scenario, redundant encoding, in the form of Forward Erasure Correction (FZC) codes [1],[2], can provide an effective protection against losses in multicast videoconferencing and video streaming ap...
متن کاملRate - Adaptive Error Control for Multimedia Multicast Services
| This paper presents a rate-adaptive error control (RAEC) protocol for multimedia multicast services in satellite-terrestrial hybrid networks. The proposed scheme considers user fairness to multicast group and adapts code rate according to the channel conditions. In order to provide fairness perceived by user application, a packet is transmitted via satellite, while the retransmission of the p...
متن کاملA feedback implosion suppression algorithm for satellite reliable multicast
In this paper, we propose a knapsack-based feedback suppression algorithm for reliable multicast transport protocols operating over a satellite network. A reliable transport protocol needs to identify the packets which failed to reach a given destination. This is achieved through feedback packets returned to the source. For multicast services, receiver feedback has been shown to lead to the fee...
