Researchers have proposed a number of co-ordination functions in literature for improving quality of service.Each one is based on different characteristics and properties.In this paper, we evaluate the performance of wireless network using PCF, DCF & EDCF.We perform simulations using OPNET IT GURU Academic Edition simulator.In the performance evaluation of the co-ordination function, the protocols are tested under the realistic conditions.Tests are performed for various parameters (Delay, Data Dropped, Throughput) in wireless Networks.This OPNET simulation shows the impact of co-ordination function for wireless networks for different parameters.
