Description

Ubiquitous heterogeneous wireless networks demand a general-purpose multi-objective vertical hand-off mechanism taking into account network dynamics as one of its decision attributes. This goal of this project was to propose a new multi-objective vertical hand-off (MOVH) mechanism that takes into account network dynamics as one of its decision attributes. We customize Multi-Objective Genetic Algorithm (MOGA) in this regard and evaluate the performance of MOVH mechanism against two most popular alternatives: GRA and TOPSIS. This evaluation comprises of both test-bed experiments and ns-2 simulation. For the test-bed experiment I have developed an Android application which selects the best target network among the existing networks using the three mechanisms: MOVH, GRA and TOPSIS and compared their performance. The results from both test-bed experiments and ns-2 simulation demonstrate that MOVH mechanism has significant performance improvement over both GRA and TOPSIS.
