An analytical study of network coding in the presence of real-time messages
Aoun, M.; Beekhuizen, P.; Argyriou, A. (2010)With network coding, two data packets are transformed into one by a simple XOR-operation. The transformed packet is transmitted and each original packet can be retrieved at its destination node through a similar XOR-operation. ... -
