worked to analyze and calculate the
effect of mutual interference on the performance of both WiFi-b
and ZigBee
networks.
The
study
justify
the

performance
by
PER,
transmission
delay
and
throughput.

Experiments
were
carried
out
on
an open simulator.
The

results
of
simulator
shows
the
following:
distance
and
centre
frequency offset between Wi-Fi-b and ZigBee are important
factors, if the distance is large enough between ZigBee and
WiFi devices (about more than 8 meters), hence the PER of
ZigBee is reduced
