This paper optimally determines the IEEE 802.15.4 medium access control (MAC) attributes macbeaconorder (BO) and macsuperframeorder (SO) (by which the periods of time that the sensor is active and non-active can be computed) such that the overall energy consumption of the network is minimized. Considering an IEEE 802.15.4 beacon-enabled network laid out in a single-hop star topology, we evaluated...
This paper presents a framework to minimize energy consumption in the medium access control (MAC) layer for wireless sensor networks. While satisfying a range of quality of service (QoS) requirements, such as the packet transmission success rate and maximum delay constraint, we optimally choose the lengths of periods in which sensors are active and inactive, such that the energy consumption per unit...
