| Popis: | This chapter presents a self-organizing TDMA (SO-TDMA) scheme in which each device independently observes the operation environment, learns about the network traffic load, and then makes decisions to adapt the protocol for smart coexistence. Channel access operation in SO-TDMA is similar to CSMA in the beginning, but then quickly converges to TDMA. This approach has the benefits of TDMA in a high-load traffic condition, and overcomes its disadvantages in low-load, heterogeneous traffic scenarios. In particular, by adapting the transmission-opportunity duration to the common idle/busy channel state information acquired by each device, the transmission-opportunity duration monotonically converges to fairness. The initial access phase of SO-TDMA is modeled as a Markov chain with one absorbing state and its required convergence time is studied. Performance of SO-TDMA in terms of effective capacity, system throughput, collision probability, delay outage probability and fairness is investigated. Simulation results illustrate its effectiveness in performance improvement, approaching the ideal case that needs complete information about the queue length and the channel conditions of devices. |
