7. Network Model:
11. If the AP wants to admit new data, it gives an “OPEN MARKET” signal (Z(t) = 1). It chooses a price p(t) andinforms the users. Users react by sending packets.
12. If the AP doesn’t want to admit new data, it sends a “CLOSED” signal (Z(t)=0). Users will NOT send any packets.
13. -The AP queues the data (Q(t) = backlog).-Observes channel state S(t). -Makes Resource Allocation decision cost(t) C.-Transmission rate = m(t) = F(cost(t), S(t))
14. The optimum avg. profit can be obtained with exact steady state distribution information for M(t) and S(t)
15. The Optimality of Two Prices Theorem
21. This example shows that using a single price does NOT always lead to optimal average profit, thus the number Two is tight
