In this paper a Personal Area Network (PAN) composed of multiple nodes, which transmit data to the PAN coordinator through the beacon-enabled mode of the IEEE 802.15.4 Medium Access Control (MAC) protocol, is considered. Upon reception of the beacon transmitted by the PAN coordinator, the nodes transmit their packets using the slotted Carrier Sense Multiple Access with Collision Avoidance algorithm defined by the standard. A mathematical model to describe the access delay statistics and the probability of packet successful reception, is provided. Performance is evaluated by changing the number of nodes, the superframe order and the packet size. The mathematical model is validated through simulation results. A comparison in terms of success probability and throughput with the non beacon-enabled mode of IEEE 802.15.4, is also provided.

Abstract
In this paper a Personal Area Network (PAN) composed of multiple nodes, which transmit data to the PAN coordinator through the beacon-enabled mode of the IEEE 802.15.4 Medium Access Control (MAC) protocol, is considered. Upon reception of the beacon transmitted by the PAN coordinator, the nodes transmit their packets using the slotted Carrier Sense Multiple Access with Collision Avoidance algorithm defined by the standard. A mathematical model to describe the access delay statistics and the probability of packet successful reception, is provided. Performance is evaluated by changing the number of nodes, the superframe order and the packet size. The mathematical model is validated through simulation results. A comparison in terms of success probability and throughput with the non beacon-enabled mode of IEEE 802.15.4, is also provided.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
