Abstract
Network coding and multiple packet reception (MPR) are used together to improve message dissemination speed in a wireless network using half duplex communication. In at least one embodiment, MPR is used to initially distribute data packets from a number of source nodes in the network to the other nodes of the network. Network coding techniques may then be used to perform backfilling within the network to supply data packets to the source nodes that were originally missed due to the half duplex constraint.
