In spite of the above advant...

Fountain codes are a class of rateless codes well-suited for communication over erasure channels with unknown erasure parameter. We analyze the decoding of LT codes, the first instance of practical, universal Fountain codes. A set of interest during LT decoding is the set of output symbols of reduced degree one (the “ripple”). The evolution of the ripple size throughout the decoding process is ...

Abstract Edge computing is emerging as a new paradigm to allow processing data near the edge of network, where typically generated and collected. This enables critical computations at in applications such Internet Things (IoT), which an increasing number devices (sensors, cameras, health monitoring devices, etc.) collect that needs be processed through computationally intensive algorithms with ...

Based on the erasure channel FEC model as defined in multimedia wireless broadcast standards, we illustrate how doping mechanisms included in the design of erasure coding and decoding may improve the scalability of the packet throughput, decrease overall latency and potentially differentiate among classes of multimedia subscribers regardless of their signal quality. We describe decoding mechani...

Although cooperative communication has been proposed at the physical layer to address multi-path fading effects, how physical layer gains with cooperative communication can translate to tangible performance benefits in end-to-end flows remains to be an open problem. This paper represents one step forward towards a deeper understanding of the interplay between end-to-end throughput and physical ...

In this paper, we propose secure relaying transmission protocols using rateless codes, where a source sends encoded packets to two intended destinations via help of intermediate relays. Employing non-orthogonal multiple access, can be sent the at same time. addition, partial relay selection methods are studied enhance reliability data first and second hops. For protecting source-relay relay-des...

In this paper two different rateless transmissionschemes are developed. In the proposed scheme, relay node candecode and forward the message to the destination if they areable to decode it, or amplify and forward the message to thedestination. Based on the analysis and simulation resultsprovided in this paper, the proposed method has bettertransmission time than the scheme which only the relay ...

Binary Erasure Channels (BEC) can be used to model transmission erasures, for example, symbol erasures in TCP’s link layer and network layer. In order to tackle the erasures incurred, the transceiver system relies on retransmission of the lost packets using acknowledgment and repeat request based schemes. This missing packet information or acknowledgments can be conveyed by the receiver to the ...
