摘要：Voice over IP is most prominent developing application layer protocol. Real time voice communication is a basic necessity in specially appointed ad hoc network. While ad-hoc network (MANET) effectively appropriate in little scale situation. In this paper, we distinguish a few factors that impacts voice quality in MANET for voice correspondence AODV and SIP protocol is utilized. In this research, to maximize the execution of MANET during voice transmission. We choose a few methodological techniques and parameter, for example, audio codec, velocity, method of media access, buffer size etc in optimum an efficient way. This paper, a cross – layer approach is intended to enhance the call setup execution of SIP-based VOIP over AODV – based MANET. Cross layer approach is utilize the SIP execution metric to enhance the call setup time in term of packet loss, network load, delay time by modify Timeto-Live parameter. For simulation, we have taken OPNET14.5 addition simulator. This paper purposed another quality of services VOIP calls over in MANET and to maintain the highest number of calls with safety and security. Utilizing this approach, the SIP singling execution expanded by 30-40% when contrasted with default appreciates ADOV MANET execution.
