Abstract: Wi-Fi and ZigBee wireless technologies share same
2.4 GHz band. However Wi-Fi uses higher power levels
compared with ZigBee. When these both technologies are used
in a device simultaneously there is data packet loss in
communication due to interference between Wi-Fi and ZigBee
wireless technologies. This condition raise retransmission of
data packets and so delay, mitigation in delivery ratio and
power consumption increases for both the technologies. In
hand held devices like PDA and Mobile power consumption is a
sensitive issue. A precise model for the effect of Interference in
both the technologies is essential. In this paper the mutual
effect of Wi-Fi Interference on ZigBee Channels by using
Castalia simulator and computed the Packet Delivery Rate
(PDR) for both ZigBee and Wi-Fi nodes. The result represents
that ZigBee has less effect on Wi-Fi Packets while Wi-Fi affects
ZigBee Packets with different degrees based on the traffic
intensity and number of nodes.
