Article Title: SUSTAINABILITY OF MOBILE COMMUNICATION NETWORKS IN NIGERIA
by Osahenvemwen O.A. and Emagbetere J.O.

Abstract:
This paper presents sustainability of mobile communication networks in Nigeria due to incessant block calls experienced by the subscribers during busy hour. The study is focused on develop blocking probability traffic model, handover blocking probability traffic model, analysis on traffic usage based on available and installed number of transmission channels. Traffic data were collected from Globacom (GLO) network 1800 MHz in Nigeria for period of two years (1st March 2010 to 29th February 2012). Subscribers usage was analyzed based on offered traffic, carried traffic, blocking traffic, available and installed number of transmission channels in this investigation. The queue theory was used to develop blocking probability traffic model, fashioned along side with handover blocking probability traffic model. Validation were done by Statistical tools such as standard error of estimate, correlation coefficient, coefficient of determination were used to compared the developed blocking probability and Erlang B blocking probability model. The result obtained from Standard Error of Estimate is 0.003, used to determine the error, correlation coefficient is 0.999954, used to determine the relationship and coefficient of determination obtained is 0.9999078, used to determine the variation between developed and Erlang B blocking probability traffic model.
Keywords: blocking probability, grade of service, transmission channels and offered traffic
