Low cost ACA-based multicast routing for multi-media applications

Energy efficient routing algorithm is an important issue in WSNs applications. In this paper we propose an ant colony algorithm based on smell factor, SUMACO, for delay-constraint multicast routing applications. Simulation results verify the speed of proposed algorithm to find the final tree of multicast routing. In Comparison with the conventional ant colony algorithm, the convergence speed and also the cost of SUMACO is strongly improved.
