This will
result in increasing the end to end delays shown in fig. 1(b)
from 0.03 at 3 nodes to around 0.5 seconds 9 nodes. Fig.
2(a) shows the original results for ZigBee nodes in a clear
site environment. Since ZigBee operates with the PAN
coordinators according to predefined schedule, then ZigBee
nodes don't effect each other for any number of nodes.
However, as it can be seen in fig.2(b) as the number of
nodes increases, the average end to end delay will increase
