Reliability and performance analysis of a base transceiver system considering software based hardware and common cause failures

In this paper a stochastic model for a Base Transceiver System (BTS) is proposed transceiver station (BTS) is the most important networking component of mobile communication system from which all signals are sent and received having both hardware and software components. The hardware and software c may have various types of major and minor faults. The aspect of hardware software interaction failure in the system is also considered. On failure, the repair team first inspects whether there is hardware or software and hardware software interaction failure, then recovery of the relevant component is done. In case of occurrence of major fault, there is complete failure of system whereas in case of minor fault system performance and capacity may decrease The possibility of occurrence of traffic Congestion in the system is also incorporated, wherein traffic congestion is automatic removed by the system. Using Markov processes and regenerative point technique various measures of system performance are obtained. Various conclusions about reliability, graphical studies. The comparative analysis of the proposed model with the existing model is also incorporated.
