Abstract: The needs to provide medical services in remote areas have motivated researchers to develop telemedicine systems. In most cases, it is very likely that very remote areas and disaster struck areas lack telecommunication infrastructure. Telemedicine system operating in such areas must have advanced wireless technology supporting it. Our approach is on MANET combined with Mobile IP and MIPV6, is the basis of infrastructure for the mobile telemedicine system. Our evaluation is based on simulating the various codecs of VoIP over MANET and presenting the ideal codec for real world implementation. In our simulations we found that G723.1 worked well in the three performance metrics, packet delivery fraction it delivered 92.4 % traffic with 6 connections. For the increasing number of connections, the performance decreased from 62.5 % at 12 connections to 24.4 % at 30 connections and decreased to 19.4 % at 36 connections. For packet delivery fraction, G.723.1 is the best performer against the other two CODECs. The delay suffered for 6 connections is 0.001 seconds and for 12 and 18 connections is 0.002 seconds. For 24 connections, the delay increases steeper than for lower number of connections. The normalized routing load for all CODECs vary within 1.022 to 1.082, hence the performances for all CODECs are almost similar for all connections. The project’s primary objective is to create a prototype of mobile telemedicine system including hardware and software that can be rapidly deployed in remote areas or in disaster condition where telecommunication infrastructures are lacking or destroyed
