Modeling the Causes of Power‐Related Network Outages Using Discrete‐Time Markov Chains

Ibrahim A Gedel, Wahab A Iddrisu

In this paper, we model the causes of power‐related network outages in Ghana using discrete‐time Markov chains. We used data consisting of 2,756 small‐scale carrier telecommunications outages occurring in Ghana, with accompanying root causes over a period of 5 years and 8 months, from August 2015 to April 2021. The results indicate that the majority (n = 1,404) of the network outages were caused by the generators while the least number (18) of outages were caused by a communication equipment. However, longer network outages were caused by fuel issues with an average outage time of 1,027.82 min over the study period. The transition probability matrix obtained from the data revealed that regardless of the present cause of the network outage, the probability that the next network outage will be caused by the generators is higher than the probability that the outage will be attributable to any other …
