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： The present invention relates to a system and method for proportional-fair resource allocation for multi-rate random access. The method includes receiving, by a device, data packets to be transmitted to an access point on a shared uplink channel, and determining, by the device, whether or not to contend for access to the shared uplink channel based on a probability of access. The probability of access is based on a data transmission rate between the device and the access point.

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： QoS aware multi radio access point for operation in TV whitespaces is disclosed. The present invention relates to operation of access points and, particularly, to operation of access points in TV whitespaces. The AP is configured to intelligently choose the radios, determine available whitespaces in the spectrum and allocate radios to the available whitespaces in the spectrum. The method determines clients that need to be serviced by the AP and assigns each client associated with AP to one of the radios. In addition, the method also takes care of QoS requirements for different services and hence every service is addressed to satisfy its QoS requirements. The method ensures that there is maximum utilization of available whitespace spectrum by accounting for the spectrum specific characteristics. The method considers bands for operation are spread across the spectrum and allocates the clients based on the availability of bands throughout the spectrum.
