Abstract:
The network selection is a decisional process aimed at determining the Radio Access Network (RAN) that a Mobile Node (MN) has to use and represents the core-function of the Vertical Handover procedure. In this paper, the authors propose a new algorithm for the network selection, called Dynamic- Technique for Order of Preference by Similarity to Ideal Solution (D-TOPSIS) that is a new formulation of the TOPSIS algorithm aimed at performing the same selection but requiring a minor number of operations and consequently reducing the time necessary to perform the selection. The main contribution of this work is the evaluation of the D-TOPSIS performance in a scenario where are available simultaneously a satellite network and Wi-Fi and WiMAX networks. The proposed approach is compared with other network selection methods found in the literature in two different cases: i) pedestrian, with a MN speed equal to 3 [m/s] and ii) vehicular, with a MN speed equal to 10 [m/s]. The numerical results show that D-TOPSIS assures a good performance as well as a limited execution time in both cases.
