graphs we can see that using PCF network resulted in even higher delay in the nodes that does not enable PCF. Furthermore‚ PCF networks reduced the number of retransmission even in the nodes without PCF enabled as PCF networks decrease the collisions and in turn the number of retransmission. Nodes with enabled PCF take the advantage of contention free period as we can see from the drop in both delay and retransmission while nodes gets affected by being in a PCF network while it does not utilize the
