Mobile Ad Hoc Networks (MANETs) [2] are an emerging type of wireless networking, in which mobile nodes associate on an extemporaneous or ad hoc basis.MANETs are self-forming and self-healing, enabling peer-level communications between mobile nodes without reliance on centralized resources or fixed infrastructure.Many ground breaking applications have been suggested for MANETs including the Voice over Internet Protocol (VoIP) [7].In order to support VoIP application over MANETs a suitable routing protocol is essential.Several routing protocols have been proposed for MANETs.In this paper, the performances of different routing protocols have been investigated and compared for VoIP application.Some popular routing protocols namely Dynamic Source Routing (DSR) [9], Ad hoc On-demand Distance Vector (AODV)[6], Temporally-Ordered Routing Algorithm (TORA) [7] have been considered in this investigation.The OPNET simulation results show that the TORA protocol is a good candidate for VoIP application.
