An Efficient Scheme to Increase the Throughput of VoIP Traffic over Satellite while Reducing Bandwidth Utilization

Voice over Internet Protocol (VoIP) offers a wide range of benefits to both enterprises and communications & network service providers. It provides an alternate way to make a telephone call as compared to the Public Switched Telephone Network (PSTN). The industry is slowly recognizing the potential of Voice over IP and many VOIP applications have been developed in the last ten years. This paper is based on an ongoing study (Msc) and aims at examining key phenomena that causes major obstacles to VoIP. This paper proposes and presents a new model of packet building namely multiple frames into a single packet (MFSP). We first, have studied the way of the VoIP packets are organized, then illustrated advantages and limitations of existing voice packet’s structures. Lastly, we have proposed a new model of packet building namely multiple frames into a single packet (MFSP). The new model mitigates the existing VoIP obstacles such as bandwidth utilization and traffic congestions. The proposed model uses to reduce the traffic through the network and packet overhead. Simulation was done using NS-2 simulator. Simulation results show the ability of MFSP to exploit the bandwidth consumption and traffic minimizing efficiently without effect on packetzing delay.
