Simulating multi-criteria handover algorithms in OMNeT++

I Multi-criteria handover algorithms have been becoming a promising solution to increase the efficiency of wireless networks. However, their evaluation in a real system demands significant resources, therefore, the use of a simulation environment is desired. For this purpose, OMNeT++ was chosen for the implementation of the multi-criteria decision making algorithms. SAW, GRA, TOPSIS and VIKOR were implemented in OMNeT++. The results of handover decisions made by means of these algorithms were analyzed with the help of an evaluation method. Four simulation scenarios with different traffic types and load were defined. The results revealed that VIKOR and GRA outperform the others for given simulation conditions.
