| Summary: | Voice over Internet Protocol (VoIP) technology has observed rapid growth in the world of telecommunications.VoIP offers high-rate voice services at low cost with good flexibility, typically in a Wireless Local Area Network (WLAN). In a voice conversation, each client works either as a sender or a receiver depending on the direction of traffic flow over the network.A VoIP technologically requires high throughput, less packet loss and a high fairness index over the network.The packets of VoIP streaming may experience drops because of competition among the different kinds of traffic flow over the network. A VoIP application is also sensitive to delays and requires voice packets to arrive on time from the sender to the receiver without any delay over a WLAN.To date, scheduling of VoIP traffic is still an unresolved problem.The objectives of this survey paper are to discuss fundamental principles of VoIP-related schedulers and identify current scheduler issues.This survey paper also identifies the importance of the scheduling techniques over WLANs. Related research work for real-time applications specifically for VoIP will also be highlighted. |
