With the increasing use of mobile devices and advances in wireless technologies, Mobile Ad-hoc Network (MANET) has drawn great attention for being part of ubiquitous networks. MANET is an autonomous collection of mobile and/or fixed nodes that can communicate together over relatively bandwidth constrained wireless links, and the network topology may change rapidly and unpredictably over time. Unlike the conventional network, MANET is decentralized radio wireless network that can be established in situations where no infrastructure exists or where deployment of infrastructure is expensive or inconvenient. As a result, routing protocols play a crucial role in managing the formation, configuration, and maintenance of the topology of the network. There has been an extensive research on performance analysis of routing protocols in MANETs. However, most of the work done on the performance evaluation of routing protocols is done using the Constant Bit Rate (CBR) traffic. This paper presents the performance analysis of MANETs routing protocols such as Ad hoc on Demand Distance Vector (AODV), Dynamic Source Routing (DSR), Temporary Ordered Routing Algorithm (TORA), and Optimized Link State Routing (OLSR) using Voice over Internet Protocol (VoIP) traffic. The performance metrics used for the analysis of these routing protocols are delay and throughput. The overall results show that the proactive routing protocol (OLSR) performs better in terms of delay and throughput than the reactive Suares Clovis Oukouomi Noutchie.
