A network node and a method for controlling a wireless network are disclosed, wherein the network node includes a receiving device configured co receive data packets from one or more other network nodes of a plurality of network nodes; one or more processors configured to determine two or more network nodes of the plurality of network nodes to which the network node may forward data packets such that a number of the determined two or more network nodes is greater than a predefined first threshold value; and a transmitting device configured to forward the received data packets to the determined two or more network nodes of the plurality of network nodes.

Network nodes, wireless networks, and methods of controlling them

A method and apparatus decode packetized data in the presence of packet erasures using a finite sliding window technique. A decoder receives packets containing uncoded and coded symbols. When a packet with a coded symbol is received, the decoder determines whether a packet sequence number is within a sliding window of w consecutive sequence numbers that are no greater than a decoder sequence number, where the number w is fixed prior to encoding. When this is the case, the decoder decodes the coded symbol into one or more of the w input symbols using the coefficient vector. Decoding may use a forward error correcting (FEC) window within the finite sliding window. Decoding also may use a technique of Gaussian elimination to produce a 'shifted' row echelon coefficient matrix.
