This Letter proposes energy-efficient error control for IEEE 802.15.1 (Bluetooth) video communication. The scheme is based on block-oriented incremental redundancy provided by rateless coding and receiver feedback. Results are presented for time-sensitive video streaming applications under a Markovian channel model. When the proposed algorithm is compared to variations of Bluetooth Forward Erro...

In communication networks, files commonly are separated into data packets and transmitted from the source node to a prescribed set of destination nodes by a method known as “store and forward”, in which data packets received are stored and then forwarded to the next node. Network coding has been proposed to replace the traditional “store and forward” model, and to improve the throughput and rob...

We consider an error-resilient stereoscopic streaming system that uses an H.264-based multiview video codec and a rateless Raptor code for recovery from packet losses. One aim of the present work is to suggest a heuristic methodology for modeling the end-toend rate-distortion (RD) characteristic of such a system. Another aim is to show how to make use of such a model to optimally select the par...

In this paper we propose a practical Random Network Coding (RNC) scheme for data distribution in a peer-to-peer (P2P) overlay network. The use of RNC incurs a significant computational cost that, till present, has limited its deployment in practical applications. In this study it is shown that RNC complexity can be lowered by using Luby Transform (LT) codes to pre-encode the data and by letting...

Wireless sensor network technologies enable a wide variety of applications (e.g., environmental monitoring). Such sensor networks are often deployed in regions that make it difficult to collect and redistribute the nodes for maintenance. However, there is often a need to reprogram all of the nodes in the network, either during application test phases on deployed networks, or to support software...

In this paper, we consider a massive uncoordinated non-orthogonal multiple access (NOMA) scheme where devices have strict latency requirements and no retransmission opportunities are available. Each device chooses a pilot sequence from a predetermined set as its signature and transmits its selected pilot and data simultaneously. A collision occurs when two or more devices choose the same pilot ...
