The complexity of health care and the increasing cost of health care in developing country such as Indonesia caused by the source of available funds and limited human resources, especially health professionals. Health monitoring through wireless body area network is one of the solution and which offers several advantages as inexpensive health services, better utilization from health care professional resource, mobility, and great experience for the patient. However, health monitoring has some challenges such as limited area coverage, mobility problem and attenuation from human body. In this paper, it describes how to research about utilization AODV, DSDV, and OLSR routing protocols from ad hoc network to improve health monitoring by using NS3 to face limited area coverage and mobility problem for static and mobile conditions. As simulation, the researcher compares the performance of AODV, DSDV, and OLSR. The researcher selected three performances of metrics: delay, throughput, and packet delivery ratio. As a result showed, OLSR has better performance for mobile and mobile has more than 50 nodes except delay, when througput, and packet delivery ratio of mobile condition OLSR show better than AODV. In static condition, throughput of AODV shows better than DSDV and OLSR, even though for mobile condition OLSR shows better than AODV and DSDV, but in some cases the delay of AODV shows better than DSDV and OLSR. This is an indication for the possible implementation of OLSR routing protocols which node is bigger than 50 nodes.
