IDMA-based cooperative partial packet recovery: principles and applications

IDMA-based cooperative partial packet recovery: principles and applications

In this article, we focus on the cooperative multi-user network model and propose a relay-assisted partial packet recovery scheme in which asynchronous interleave-division multiple-access (IDMA) with iterative chip-by-chip multiuser detection (MUD) is used for the recovery of partial packets from multiple sources. In packet transmission, only a few erroneous bits may cause the entire packet to ...

Maranello: Practical Partial Packet Recovery for 802.11

Partial packet recovery protocols attempt to repair corrupted packets instead of retransmitting them in their entirety. Recent approaches have used physical layer confidence estimates or additional error detection codes embedded in each transmission to identify corrupt bits, or have applied forward error correction to repair without such explicit knowledge. In contrast to these approaches, our ...

Effective Partial Evaluation: Principles and Applications

We report here a successful experiment in using partial evaluation on a realistic program, namely the Sun commercial RPC (Remote Procedure Call) protocol. The Sun RPC is implemented in a highly generic way that offers multiple opportunities of specialization. Our study also shows the incapacity of traditional binding-time analyses to treat real system programs. Our experiment has been made with...

A cooperative packet recovery protocol for multicast video

In this paper we describe a protocol that improves the quality of multicast video or audio transmissions by recovering lost packets. The protocol is applied to a corporate intranet, and measurements indicate that significant improvements in audio/video quality are achieved. A unique characteristic of this protocol is that it can be used on current MBone sessions without changing the operation o...
