M-RATS: Mobile-Based Radio Access Technology Selector for Heterogeneous Wireless Environment
Wireless heterogeneous environments are common reality today and will be even more in the future. This paper is focused on providing wireless access selection method for the future mobile terminals that will use naturally inspired algorithms for best network selection. The novel algorithm uses mobile terminal measurements from different radio access technologies within a given time window. The network selection is based on specified criteria, which number can be increased as needed. Each criterion is modeled with membership function associated with Fuzzy Logic controllers, which are optimized by using Particle Swarm Optimization. Each criterion is weighted, with aim to assign the influence on the decision for radio access network.
