Center node: "wireless broadcast with network coding in mobile ad hoc networks dragoncast"
  Abstract: 6569 — July 2008 — 23 pagesAbstract: Network coding is a recently proposed method for transmittingdata, which has been shown to have potential to improve wireless network per-formance. We study network coding for one speciﬁc case of multicast, broad-casting, from one source to all nodes of the network.We use network coding as a loss tolerant, energy-eﬃcient, method for broad-cast. Our emphasis is on mobile networks. Our contribution is the proposal ofDRAGONCAST, a protocol to perform network coding in such a dynamicallyevolving environment. It is based on three building blocks: a method to permitreal-time decoding of network coding, a method to adjust the network codingtransmission rates, and a method for ensuring the termination of the broadcast.The performance and behavior of the method are explored experimentallyby simulations; they illustrate the excellent performance of the protocol.Key-words: wireless networks, networkcoding, broadcasting, multi-hop, min-cut, hypergraph, control
