Book Description
ABSTRACT: Due to the remarkable growth of subscribers in cellular systems and mobile communication networks, users expect the same reliable services over the air interface during all operating conditions. This is creating the need to design more robust and survivable wireless access networks. The design of survivable networks requires performance analysis in the wake of failure. However, research has shown that the effectiveness of network analysis is highly dependent on the underlying system modes that are used. This study develops the effects of population distribution and transportation infrastructure on various channel allocation protocols under normal, hot spot and failed conditions. For this we select three geographic areas (small, medium and large cities) and perform various simulation runs by varying different geographic data sets under all above stated conditions and compare the performance of channel assignment protocols in terms of new call blocking, forced termination and handover activity. The results illustrate the extent to which incorporation of empirical data from the physical environment affects the conclusions that are drawn with respect to mobile network performance and survivability analysis.
