Abstract—Mobile Ad Hoc Networks (MANETs) are more and more popular and applied in a wide range of applications such as healthcare, traffic control, military, rescue, and smart cities. However, the real performance of MANETs is still far from our expectations. Hence, there exists a massive amount of works considering this problem. Due to the performance of MANETs mainly dependent on the routing protocol employed, in this paper, we review the proposed routing protocols for MANETs published on the IEEE digital library in the last decade to determine an overall purpose about research directions. Based on these results, we perform a comparison of the performance of four typical traditional routing protocols, namely AODV, DSR, OLSR, and DSDV. We first design and implement different simulations so that all necessary performance metrics can be observed and measured. Then, we give comparative analyses of the obtained numerical results. From insight experiments, we may conclude that, for light traffic and low mobility MANETs, OLSR and DSDV work well. However, for heavy traffic and high mobility MANETs, AODV and DSR are dominant. Thus, we believe that new routing protocols for MANETs must have the ability to work efficiently in both cases.
