Comparison of CSMA/CA and TDMA.

Comparative parameters	CSMA/CA	TDMA
Synchronization	Not essential	Essential
Packet failure	Cause less delay	Cause more delay
Dynamic	Work well to handle network changes	Perform poorly in a dynamic environment
Bandwidth utilization	Medium	High
Power consumption	Medium	Low-medium
