Performance analysis of IEEE 802.15.4 non-beacon mode with the unslotted CSMA/CA
Tae Ok Kim, Jin‐Soo Park, Hak Jin Chong, Kyung Jae Kim, Bong Dae Choi · IEEE Communications Letters · 2008
We provide a simple mathematical model of IEEE 802.15.4 unslotted CSMA/CA by busy cycle of M/G/l queueing system to obtain several performance measures. Our performance measures can be used for determining the optimal number of devices while supporting the required QoS constraints on the average packet delay and the packet loss probability, and also for calculating battery lifetime.
