The Study on a New Immune Optimization Routing Model

The integrated network (mixed with fixed network, cellular wireless network and ad hoc network etc.) would have different dynamic properties to the single-technique-based network, such as the movement of nodes and the change of delay of links. In this paper, we propose a new dynamic multicast routing model with a mechanism called local rearrangement to handle the changes in integrated network. Furthermore, D-IOA, an immune algorithm based on clone process, which employs gene library to improve the effectiveness of D-IOA to meet the real-time requirement in online multicast routing fields, is given to optimize the multicast sub-tree within the range of local rearrangement. The simulation results indicate that our algorithm balances three metrics better compared with other two famous dynamic multicast routing algorithms.
