A new beacon order adaptation algorithm for IEEE 802.15.4 networks

The new IEEE 802.15.4 standard enables deployment of low-rate low-power personal area networks. It provides a mechanism for adaptation of the protocols duty cycle during runtime. In this paper we propose BOAA, a new algorithm for beacon order adaptation in IEEE 802.15.4 star-topology networks. By observing the communication frequency, the coordinator in such a network determines the required duty cycle and adapts the beacon interval accordingly. Investigations reveal that the algorithm enables power saving with a trade-off according to message delay
