Abstract

Based on the Mendia and Sarkar's algorithm [8], we propose an optimal and nonredundant distributed broadcasting algorithm in star graphs. For an $n$-dimensional star graph, our algorithm takes $O(n\log_2 n)$ time and guarantees that all nodes in the star graph receive the message exactly once. Moreover, broadcasting $m$ packets in a pipeline fashion takes $O(m\log_2 n + n\log_2 n)$ time due to the nonredundant property of our broadcasting algorithm.Index Terms驴Broadcasting, interconnection networks, star graphs.
