Location-aided multicast routing optimization with bandwidth restraint

One of Overlay multicast research is its related topology design for the routing optimization. To improve the related robustness and scalability issues, this paper proposed a location-aided multicast routing scheme based on genetic algorithm (GARouting) to construct a region-divided topology tree for the multicast routing in overlay network. The scheme firstly accessed the geographic information of Multicast Service Nodes to build the region-divided topology structure for the routing scalability. And then GARouting selected genetic algorithm to implement the region division operation for the routing robustness. Finally the scheme applied a multicast SPT method to form a region-divided routing tree. Simulation results demonstrated that the proposed scheme indicates better routing performance in terms of robustness and scalability.
