Resumo(s)
The simulation analysis is important approach to developing
and evaluating the systems in terms of development
time and cost. This paper demonstrates the application
of Time Division Cluster Scheduling (TDCS) tool
for the configuration of IEEE 802.15.4/ZigBee beaconenabled
cluster-tree WSNs using the simulation analysis,
as an illustrative example that confirms the practical applicability
of the tool. The simulation study analyses how
the number of retransmissions impacts the reliability of
data transmission, the energy consumption of the nodes
and the end-to-end communication delay, based on the
simulation model that was implemented in the Opnet Modeler.
The configuration parameters of the network are obtained
directly from the TDCS tool. The simulation results
show that the number of retransmissions impacts the reliability,
the energy consumption and the end-to-end delay,
in a way that improving the one may degrade the others.
