IEEE 802.15.4 with uplink transmission

The authors derive the probability of access delay calculate throughput of PAN IEEE 802.15.4 in the beacon enabled mode. They model the network using the theory of discrete time markov chains and M/G/1/K queues. The model considers ACK uplink transmission in non-saturation mode.

It includes the impact of different parameters such as packet arrival rate, number of stations, the finite size of individual node buffers, packet size, and inactive period between the beacons.The main factors that detemine performance at the MAC layer include not only network parameters (size) and device parameters (buffer size), but also traffic parameters such as packet arrival rates, duty cycle, and duration of inactivity periods. They combine the theory of discrete-time Markov chains and the theory of M/G/1/K queues in order obtain the access probability that the medium is idle and the probability distribution of the packet queue size at the device,etc.
