Эта книга представляет многоканальный протокол с одним радиоканалом как новую парадигму для IEEE 802.11 Distributed Coordinated Function (DCF) в беспроводных сенсорных сетях (WSNs). Традиционно WSN не нуждались в высокой скорости передачи данных и пропускной способности, но с развитием технологий, мультимедийных потоков, мобильности узлов и автомобильного трафика стало тенденцией к сбору данных, поэтому возникла необходимость в протоколе высокой скорости передачи данных для WSN. Данная книга посвящена разработке алгоритма, который применяет многоканальность в алгоритме IEEE 802.11 DCF back-off для уменьшения времени ожидания узла и увеличения пропускной способности при попытке получить доступ к среде. Сначала были изучены MAC-подслои для MAC-протокола IEEE 802.15.4 и IEEE 802.11, чтобы помочь понять схему 802.11 и 802.15.4 CSMA/CA. Производительность обеих схем была исследована и оценена с помощью результатов моделирования. Во-вторых, был рассмотрен предложенный алгоритм обратного отсчета MC-DCF для многоканального доступа на основе протоколов 802.11 DCF. Этот алгоритм позволяет узлу иметь доступ к
