Performance Analysis of ZIGBEE (IEEE 802.15.4) Beacon-Enabled Mode, The aim is to develop a flexible mathematical tool able to study beaconenabled 802.15.4 networks organized in different topologies. Both for the contention access period (CAP) and the contention-free period (CFP) defined by the standard are considered. The model is a useful tool for the design of MAC parameters and to select the better topology. Personal Area Network (PAN). A collection of cooperating devices which are associated and share the same address space. PAN coordinator through direct links or multiple hops, the PAN coordinator, each node tries to transmit its packet using the super frame structure defined by the zigbee protocol. The slotted carrier-sense multiple access with collision avoidance (CSMA/CA) algorithm used in the CAP portion of the super frame is analytically modeled, the performance metrics model is validated through simulation results, and Beacon-Enabled Mode data transfer is validated through hardware product.
