Applying Data Fragmentation in IEEE 802.15.4: Modeling and Analysis Under Unsaturated Traffic

The IEEE 802.15.4 standard, which is developed for low rate applications, offers low latency and energy consumption for wireless sensor networks. The use of the standardized slotted Carrier Sense Multiple Access (CSMA/CA), as a channel access mechanism, can, however, lead to wastage of the bandwidth utilization and an additional transmission delay. This drawback is mainly caused by deferred transmission in the CSMA/CA algorithm at the end of the super-frame, when there is not sufficient time to complete the frame transmission.
