TLDR
It is shown that an adaptive forward error correction mechanism, which adjusts the level of redundancy in response to packet loss behavior, can quickly accommodate worsening channel characteristics in order to reduce delay and increase throughput for reliable multicast channels.Abstract:
This paper describes an experimental study of a proxy service to support collaboration among mobile users. Specifically, the paper addresses the problem of reliably multicasting Web resources across wireless local area networks, whose loss characteristics can be highly variable. The software architecture of the proxy service is described, followed by results of a performance study conducted on a mobile computing testbed. The main contribution of the paper is to show that an adaptive forward error correction mechanism, which adjusts the level of redundancy in response to packet loss behavior, can quickly accommodate worsening channel characteristics in order to reduce delay and increase throughput for reliable multicast channels.read more

A Survey of Multicasting over Wireless Access Networks
Jean-Marie Vella,Saviour Zammit +1 more
TL;DR: A survey of the research effort invested in the analysis of multicasting over wireless access networks from the late nineties onwards is presented, showing that reliability and resilience was not the only interest in which researchers have shown.

Protocol design for scalable and reliable group rekeying
TL;DR: A scheme for identifying keys, encryptions, and users, and a key assignment algorithm that ensures that the encryptions needed by a user are in the same packet is presented, which provides reliable delivery of new keys to all users eventually.

Adaptive forward error correction
TL;DR: In this paper, an adaptive forward error correction (FEC) scheme was proposed for video streaming over a wireless network, where an FEC encoder and an adaptive FEC device are used to determine a number of redundant packets to transmit with the encoded k packets, based upon receiving one or more feedback messages.

Modeling multicast packet losses in wireless LANs
Chiping Tang,Philip K. McKinley +1 more
TL;DR: A new approach for modeling packet losses that explicitly accounts for spatial loss correlation is proposed and the improved accuracy of the new approach, compared to conventional models, is demonstrated by comparing results of simulations and experiments.

A reliable multicast framework for light-weight sessions and application level framing
TL;DR: An adaptive algorithm that uses the results of previous loss recovery events to adapt the control parameters used for future loss recovery is demonstrated, and the reliable multicast delivery algorithm provides good performance over a wide range of underlying topologies.

Parity-based loss recovery for reliable multicast transmission
TL;DR: The results show that introducing FEC as a layer below ARQ can improve multicast transmission efficiency and scalability and that there are substantial additional improvements when the two are integrated.

Parity-based loss recovery for reliable multicast transmission
TL;DR: The results show that introducing FEC as a transparent layer below ARQ can improve multicast transmission efficiency and scalability, however, there are substantial additional improvements when FEC and ARQ are integrated.

A comparison of sender-initiated and receiver-initiated reliable multicast protocols
TL;DR: It is shown that a receiver-initiated error control protocol which requires receivers to transmit NAKs point-to-point to the sender provides higher throughput than a sender- initiated counterpart for both classes of applications.
