All-to-All Broadcast by Flooding in Communications Networks
September 1989 (vol. 38 no. 9)
pp. 1330-1333
The author establishes the worst-case time complexity of all-to-all broadcast, which involves the simultaneous broadcast of messages from each node in a network to each other node, as with the dissemination of network status information for adaptive routing in ARPANET, by flooding. It it shown to be almost two times the optimum. This suboptimality of flooding results from the selection method p
