Abstract

As the number of satellite constellations increases, a subscriber may be covered by multiple satellite networks simultaneously, and access to different satellite networks can obtain different communication qualities. In this paper, we firstly propose the access network selection algorithm based on analytic hierarchy process (AHP) method in a software-defined satellite network (SDSN) architecture. The weights obtained by AHP method do not consider the real-time changes of the network parameter values, which may result in unbalanced load. In order to solve this problem, two improved algorithms based on AHP-entropy weight method (AHP-EW) and punitive variable weight method (PVW) are proposed, respectively. In the algorithms, the weights can be dynamically modified objectively according to the real-time parameter values of the network index. The simulation results show that the improved algorithms can select the most suitable network and effectively balance the load among the networks on the basis of ensuring the service quality requirements of the subscriber.
