Research Area: Mobile Ad Hoc Networks
The Vertical Handover and the related NetworkSelection process play a fundamental role in supporting reliablecommunications over MANETs. The goal of the Network Selectionis to determine the Radio Access Network (RAN) that a MobileNode (MN) has to use among several available RANs. Thisdecision process finds out the RAN that fits the MN requirementsand has to provide the decision as rapidly as possible. Acomputationally heavy Network Selection algorithm can impactthe whole handover process because it waits until the selection iscarried out. This waste of time can have negative consequencesin the quality of communications. The main contribution of thispaper is the definition of a new Network Selection algorithmbased on a different formulation of the Technique for Orderof Preference by Similarity to Ideal Solution (TOPSIS) methodfound in the literature, called Dynamic-TOPSIS (D-TOPSIS).It is aimed at performing the same selection of the TOPSISbut with a significant reduction of necessary computationalload. Finally, the numerical results highlight the execution time reduction obtained by applying the D-TOPSIS with respect to the standard algorithm, and other Network Selection techniques usually applied within Vertical Handover Processes.
