SpletEytan Modiano Slide 10 Throughput of Slotted Aloha • The throughput is the fraction of slots that contain a successful transmission = P(success) = g(n)e-g(n) – When system is stable throughput must also equal the external arrival rate (λ) – What value of g(n) maximizes throughput? – g(n) < 1 => too many idle slots – g(n) > 1 => too many … SpletThe maximum throughput for the slotted ALOHA occurs at G = 1.0 ( Equation 6.21) and it is equal to 1/ e or about 0.368. This implies that at the maximum throughput, 36.8% of the time slots carry successfully transmitted packets. The best channel utilization with the slotted ALOHA protocol is 36.8% — twice the pure ALOHA protocol.
