slotted aloha efficiency derivation
assume that each node attempts to transmit a frame in each slot with probability p. (That is, we assume that each node always has a frame to send and that the node, transmits with probability p for a fresh frame as well as for a frame that has already, suffered a collision.) (A node, frames to send.) The objectives are to examine how N fertilization (and associated soil acidification) affect movement of carbon through three organic matter pools with different residence times: microbial biomass, particulate organic matter, and mineral-associated organic matter. Using the value of p found in (a), find the efficiency of slotted ALOHA by letting N approach infinity. 10 0 obj

WebThroughput 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 () What value of g(n) maximizes throughput? The efficiency of an ALOHA system is that fraction of all transmitted frames which escape collisions that is which do not get caught in collisions. By retransmitting with probability p, we mean that the node effectively, tosses a biased coin; the event heads corresponds to retransmit, which occurs, with probability p. The event tails corresponds to skip the slot and toss the coin, again in the next slot; this occurs with probability (1 p).
