A Statistical Approach to Efficiency and Reliability Analysis of Embedded GSM Remote Billboard Design

Embedded System designs (ESD) comprises of portable devices such as digital watches, modems, MP3 players, including large stationary installations like traffic lights, factory controllers, complex hybrid vehicles, avionics, etc. Various contributions have been made in developing embedded systems both on low and complex systems with little consideration on reliability analysis of these systems. In this regard, the factors that contribute to the overall reliability of these systems have been scarcely investigated on. This research then addresses these issues by developing a Prototype GSM Billboard Display System (PGBDS) for limitless geographical reach, based on embedded AT89C51 Microcontroller chip with its associated peripherals mounted inside a large chassis or enclosure. We used an independent statistical approach to test a null hypothesis based on the responses of expert implementers in a sample population. Electronics Development Institute, Awka-Nigeria, was used as the testbed for the sample population. Independent-Variable Data Validation Scheme (IVDVS) is applied to analyse the data collected while accepting the null hypothesis, showing adequate agreement between computed results and actual prototype system reliability at 0.05 significance levels.
