CBT - VOIP: CODEC BASED TECHNIQUE TO REDUCE VOIP TRANSMISSION DELAY IN MOBILE AD-HOC NETWORKS

Abstract

Mobile and wireless technologies provide Voice over Internet Protocol (VoIP) service to the users with the help of internet. However, there are some limitations with respect to bandwidth, delay, jitter, etc. While it meets congestion and heavy load on the network, it drastically consumes and wastes the resources unnecessarily. Likewise, Mobile Ad-hoc Networks (MANETs) is a part of ad hoc network to provide VoIP communication among the users without the aid of any internet facilities. Since the nodes are mobile in MANETs, it faces many challenges like dynamic topology, limited bandwidth and battery power in order to provide Quality of Service (QoS). This paper proposes a CBT-VoIP technique for reducing the VoIP transmission delay. Ultimately, it helps to improve QoS in MANETs.
