Novel validation approach for network selection algorithm by applying the group MADM

Variety of vertical handoff algorithms (VHA) based on multi attribute decision making (MADM) methods have been proposed to help the user to select dynamically the best access network in terms of quality of service. However, there is no study that examines the validity of MADM methods which led to inefficient network selection due to inconsistent ranking outcomes. To address this issue, this paper proposes a new validation approach based on group MADM methods. This approach takes into account the weighting algorithms and allows to select the most valid ranking algorithm which can be used in specific traffic classes for network selection decision. Simulation results are presented to illustrate the effectiveness of our new validation approach for the network selection algorithm.
