ABSTRACT

In this paper, we present a heuristic algorithm for k-broadcasting in an arbitrary network. This heuristic generates optimal k-broadcast time in grid graph when k \ge 2. In two-dimensional torus graph, it also generates optimal k-broadcast time when k \ge 3, while giving a bound of \left[ {\frac{m} {2}} \right] + \left[ {\frac{n} {2}} \right] + 1 when k = 2, where m and n are the number of rows and columns in the graph. In practice, the new heuristic outperforms best known 1-broadcast algorithm for three different network design models. The new algorithm runs fast. The time complexity of the algorithm is O(R \cdot m), where R represents the rounds of broadcasting, and m stands for the total number of edges in the graph.
