Исследование и оптимизация работы беспроводной сенсорной сети на основе протокола ZigBee
Компьютерные исследования и моделирование, 2012, т. 4, № 4, с. 855-869

В работе рассматриваются вопросы алгоритмов функционирования беспроводных сетей на основе модифицированного стека протоколов ZigBee/IEEE 802.15.4 и проблемы энергосбережения с одновременным уменьшением времени доставки сообщений. Даны теоретические выкладки и описаны алгоритмы распределения ролей и установки расписаний для маршрутизаторов. Приведены и проанализированы результаты проведённых натурных экспериментов, а также численных экспериментов выполненных с помощью открытого программного комплекса ns-2.

Ключевые слова: сенсорные сети, беспроводные сети, ZigBee, IEEE 802.15.4, дискретно-событийное моделирование, оптимальное расписание.

Study and optimization of wireless sensor network based on ZigBee protocol
Computer Research and Modeling, 2012, v. 4, no. 4, pp. 855-869

Algorithms of wireless sensor networks operation based on modified ZigBee/IEEE 802.15.4 protocol stack and problems of energy saving with simultaneous decrease of network latency are studied. Theoretical computations are given. Roles distribution and routers schedule assignment algorithms are described. Both results of experiments carried out with real devices and results of simulations with ns-2 (open-source network simulator) are given and analyzed.

Keywords: sensor network, wireless network, ZigBee, IEEE 802.15.4, discrete-event simulation, optimal schedule.
