Recently, rateless codes have been employed in packet forwarding protocols of delay tolerant networks (DTNs) to improve the network reliability and to cope with packet loss. However, in intermediate range, where the number of received coded packets is less than the number of source packets, rateless decoder cannot recover any source packets. However, in some applications such as multimedia content...
We address the problem of exchanging broadcast packets among multiple wireless terminals through a single relay node. The objective is to evaluate the delay and throughput gains of network coding over plain routing. We compare digital network coding at the packet level with analog network coding based on scheduled or random access of terminal transmissions that are forwarded by the relay node. For...
