基于主客观权重的异构网络选择算法

Abstract

Abstract:

A heterogeneous network selection algorithm based on the subjective and objective weights is proposed for the selection of the most optimal access network.On the user side,analytic hierarchy process (AHP) is used to determine the user preference.On the network side,criteria importance by intercriteria correlation (CRITIC) method is used to determine the network objective state.Finally,the user preferences and network status collaborative judgment are integrated for the choice of the optimal network by technique for order preference by similarity to an ideal solution (TOPSIS).Simulation results show that the method can comprehensively consider the user service type and network performance objectively,and improve the rationality and validity of network selection.

Key words: heterogeneous network;network selection algorithm;analytic hierarchy process;criteria importance through intercriteria correlation;technique for order preference by similarity to an ideal solution
