- Abstract:
-
Based on analyzing the defects of a heuristic algorithm of greedy strategy, an ant colony algorithm was imported to solve the minimum MPR set. First of all, a node and its out and indegrees were defined, and in accordance with the out and indegree constraints of the node, ant colony algorithms were given based on the graphics to find the minimum MPR set. Then, three kinds of ant colony algorithm models, the AntCycle, AntQuantity, and AntDensity models, were improved, and the convergence curves of the three kinds of models were analyzed and tested. An ideal uniform topology and a circular distribution topology were both used in experiments. Former experimental results showed that the AntCycle model was faster in convergence speed; the latter results showed that the AntCycle and AntDensity models both have advantages. Therefore, ant colony algorithm model selection of the minimum MPR set might be subject to topology. Finally, OPNET was used based on the above algorithm for simulation. It adopted the data link’s pointtomultipoint calling mode. The selected statistics show connectivity and data consistency among the nodes, which means that the algorithm is reasonable.
