A fuzzy genetic algorithm for QoS multicast routing

摘要

It is impossible for nodes in an actual dynamic network to maintain the global accurate network state information. Therefore, it is unreasonable and inefficient to express the QoS constraints with deterministic crisp values. In this paper, the QoS multicast routing problem is solved by use of the generalized fuzzy-constrained fuzzy-optimization model. Both imprecision of the network state information and the fuzziness of QoS constraints are taken into account invoking fuzzy set theory. A new fuzzy genetic algorithm for QoS multicast routing is also presented and simulation experiments demonstrate that the algorithm is efficient.
