A QosBased Performance Evaluation of Wireless Networks Using OPNET Modeler
WLANs are being used for military, multimedia and health application, where high system performance and the ability to stay in link are extremely required. It can be considered the wireless version of Ethernet, which supports best-effort service. The authors have measured the performance of next generation wireless networks in terms of delay; media access delay, throughput and retransmission attempts. These are essential metrics which are used to identify the performance of a given wireless networks. Based on these measurement, the decision for networks selection is made i.e. using vertical handover or alternate handover, user's call/connection is seamlessly transferred to good QoS enabled network.
