Performance Analysis of VoIP traffic over MANETs Under Different Routing Protocols

in recent decades, Voice over Internet Protocol (VoIP) has been extensively utilised as an individual’s communication method. A mobile ad-hoc network (MANET) is a wireless network that lacks infrastructure and has a topology that can change dynamically over time. Many types of routing protocols were developed for MANET. Every routing protocol has its characteristics. This paper intends to quantitatively evaluate the impact of OLSR, AODV, and DSR on VoIP in MANET. Optimised Network Engineering Tools (OPNET) version 14.5 was selected to experiment. According to the experiment results, the best VoIP performance was under the OLSR protocol.
