Abstract

In Highways wireless mobile networks, in order to ensure that ongoing calls are not dropped while the users roam among cells, handoff calls may be admitted with a higher priority as compared to new calls. One way to improve system performance of cellular networks is to use efficient handoff models when users move between cells. In this paper, Non-priority Model (NPM) and Guard Channel Model (GCM) are presented and evaluated to improve the utilization of wireless network resources. However, Simulation results show that the required Grade of Service (GoS) of handoff calls is guaranteed at low and medium traffic loads only regardless that improvement of handoff calls blocking probability is at the expense of blocking probability of new calls. So, we reveal how to overlay highway microcells by macrocells to improve many teletraffic parameters. The new proposed models are called integrated Satellite/Terrestrial (Sat/Terr) models. Teletraffic performance of the proposed models is investigated using simulation technique. Simulation results are accumulated to evaluate the system performance.
