—The optimal communication spanning tree (OCST) problem finds a spanning tree that connects all node satisfies their communication requirements for a minimum total cost. In this paper, we present a new method of finding optimal solution for OCST problem based on Ant Colony Optimization (ACO) to reduce search space mentioned above but still converge to a global good solution. Our algorithm take account into node biased encoding (NBE) scheme to find nearly optimal solution. The new algorithm can achieve a result that is better than known heuristic algorithms do, as verified by a set of public benchmark problem instances.
