A new hybrid GRASP with the pilot method for the delay-constrained multicast routing problem
Multicast routing problem is a well know optimization problem for transmitting real-time multimedia applications in telecommunication networks.As the underpinning mathematical model,the constrained minimum Steiner tree problem in graphs is a well-known NP-complete problem.In this paper we investigate a new hybrid GRASP (Greedy Randomized Adaptive Search Procedure) approach where a pilot method is applied to further enhance the search for the Delay-Constrained Lenst-Cost (DCLC) multicast routing problem.Experimental results demonstrate the efficiency of the hybrid GRASP algorithm and the contributions of the post-processing pilot method to better solutions in most cases.The proposed GRASP approach is a competitive approach in solving the DCLC multicast routing problem.
