This paper presents a novel approach to modeling and quantitatively analyzing retrial mechanisms in large-scale networks within the massive and sporadic access scenario. We focus on exponential backoff, fixed time-slot, and fixed probability retrials. Our simulations demonstrate significant performance improvements, with increased success probability and reduced latency. We show that performance improves as the backoff parameter$n$increases or the fixed time-slot parameter$m$decreases, reaching optimal results when$n$approaches infinity and$m$is zero. Additionally, we identify an optimal retransmission probability$p$within the fixed probability framework.
