The standard of IEEE 802.15.4 is able to achieve low-power transmissions in low-rate and short-distance wireless personal area networks. It employs the slotted carrier sense multiple access with collision avoidance (CSMA/CA) for the contention ...
This paper analyzes the non-persistent Carrier Sense Multiple Access (CSMA) mechanism, and simulates its application in IEEE 802. 15. 4. We find that throughputs are relevant to the normalized propagation delay and the Basic Time Period (BTP) of slotted ...
The low-rate wireless personal area networks WPANs, as wireless sensor networks WSNs, suffer from many constraints. The IEEE 802.15.4 standard proposes the slotted CSMA/CA as a communication channel access mechanism with collision avoidance that take ...
