An Adaptive Scheme for Active Periods Schedule in IEEE 802.15.4 Wireless Networks
Marco Ferrari, Luca Pizziniaco · 2006
IEEE 802.15.4 is a new standard for low-rate wireless personal area networks defining MAC and physical layers. On top of this technology, the ZigBee Alliance built a network layer and an application framework. In most of the application scenarios the key requirement is an extremely low energy consumption in order to guarantee a long network lifetime. This is achieved through energy management schemes that nodes switch between active and sleep modes. In this paper we present a new adaptive scheme, DynAMo, for active periods schedule that dynamically adjust starting points and durations in a distributed way taking into account traffic statistics and routing information.
