    摘要: A method and computer program product for providing a random linear coding approach to distributed data storage is presented. A file is broken into a plurality of pieces. For every peer (peer means storage-location with limited storage space), the number of coded-pieces the peer can store is determined. Each of the coded-piece is determined by taking random linear combination of all the pieces of the entire file. The associate code-vector is stored for every coded-piece. The file is retrieved by collecting code-vectors and the coded-pieces from the peers and viewing the collected code-vectors as a matrix. When a dimension of the matrix is equal to the number of pieces of the file, the file is recovered using the collection of code vectors in the matrix.

    摘要: A method, apparatus and computer program product for providing rapid information dissemination using network coding is presented. A coded message including a payload and a code vector, is transmitted from a first node of the network to a second node of the network. The information thus stored can also be retrieved by collecting code vectors from at least one node and viewing the collected code vectors as a matrix. A determination is made regarding whether a dimension of the matrix is equal to a predefined number. When the dimension of the matrix equals the predefined number, the information is retrieved using the collection of code vectors in the matrix.

    摘要: A method, apparatus and computer program product for a peaky binning Relaying Scheme for Wideband/Low Signal-To-Noise Ratio (SNR) Wireless Communications is presented. In a computer system having a source node (S), a relay node (R) and a destination node (D), the method includes transmitting by S a message (m), wherein a first subset of m (m1) is transmitted to R and wherein a second subset of m (m2) is transmitted to D. The method further includes decoding by R a bin index from the m1 and forwarding the bin index to D. Additionally the method includes receiving the bin index at D and decoding the bin index and receiving at D the m2 and decoding the m2. The method also includes determining by D the value of m from decoded values of the bin index and the m2.
