"Voice over IP VoIP is a form of voice speech that uses data networks, for transmission of voice traffic over IP-based networks to transmit voice signals. The signal is correctly encoded at one end of the communication channel, sent as packets through the data network, then decoded at the receiving end and transformed back into a voice signal. It has a potential and offering a choice to the traditional telephony systems due to its high resource utilization and cost efficiency. Meanwhile, Wireless Local Area Networks (WLANs) have become an ever present networking technology that has been deployed around the world. Driven by these two popular technologies, Voice over WLAN (VoWLAN) has been promising as an infrastructure to provide low-cost wireless voice services. However, wireless technology was not designed to support voice transmission and recently enhancing its service quality is one of the main issues to be solved. Several metrics such as delay, jitter, and packet loss have impact on the QoS of VoIP. Minimizing total transmission delay, jitter and packet loss would maximize transmission throughput thus improving quality of service. In this research a VoIP transmission algorithm would be designed to reduce transmission delay in order to increase quality of service of VoIP. This research work is aimed to utilize IP protocols and provide a method to improve VoIP performance. © 2011 IEEE."^^ . "2011" . . .
