Network Access Selection Algorithm Based on Balanced Profits between Users and Network

الملخص EN

A network access selection algorithm based on the intuitionistic fuzzy analytic hierarchy process (AHP) and bilateral profit drive is proposed in this study for addressing problems regarding user–network bilateral profits.

User preference, business demands, and network parameter changes are comprehensively considered in the algorithm.

First, the initial weights centered at users are gained by intuitionistic fuzzy AHP.

Second, the network participates in network access selection as a subject with competitive consciousness, and the entire selection process is transformed into a multiobjective optimization problem by the construction of a competitive model, thereby obtaining dynamic competitive weights.

Third, the initial weights centered at users and the dynamic competitive weights are combined to obtain comprehensive weights.

In this way, the dynamic adjustment of comprehensive weights is realized.

Finally, candidate networks are ordered according to a comprehensive performance evaluation, and the optimal one is selected.

The proposed algorithm is validated by simulation results to be valid in reducing the blocking rate of networks and optimizing network resource allocation.

Therefore, it not only protects user–network bilateral profits but also maximizes comprehensive profits.
