Simulation model of beacon enabled 802.15.4 networks with OPNET modeler

This IEEE 802.15.4 comes upon the LR-WPAN family which has low cost low power and the devices are battery driven with several applications. Here we analyze the MAC layer performance of such networks which use slotted CSMA/CA channel access mechanism. Our analysis is based on a OPNET simulation model, designed under star topology with a PAN coordinator and n no of transmitting nodes. Simulation has been done for different MAC parameter settings and for different number of n. Impact of hidden node is also considered. We also analyze the probability of receiving packet with the variation of different parameters.
