Using Delaunay triangulation to construct obstacle detour mobility model

With the rapid growth in wireless communication technologies, mobility management research is in great demand. Simulation has become an effective method to study the performance of many mobility issues. A realistic mobility model not only reflects mobile user behavior, but also affects correctness of the simulation results. In a wireless environment, obstacles usually exist within the coverage area. We propose a new detour model by using Delaunay triangulation through the incorporation of obstacles. The proposed mobility model can create detour paths as long as there exist gaps among obstacles. Comparative studies show that our proposed model can construct more detour paths than the Voronoi model.
