Performance Comparison and Analysis of Voice Communication over Ad Hoc Network

Currently, voice traffic (both local and long-distance) is gradually moving from traditional circuit-switched networks to IP-based, packet-switched networks. Another dominant trend is the development of mobile ad hoc networks technology. In this work, a simulation based performance analysis of ad hoc routing protocols is presented for establishing VoIP conversation sessions by mobile users in an ad hoc network scenario. The two primary performance metrics (the packet delivery rate and end-to-end delay) for measuring the voice communication are evaluated by varying the routing protocols, number of VoIP conversation sessions and user mobility
