A Mobile Ad-hoc NETwork (MANET) is different from other wireless networks in many ways. One of the key differences is that a MANET is a multi-hop wireless network,i.e., a routing path is composed of intermediate mobile nodes and wireless links connecting them. In this paper, Heterogeneous Mobile Ad-hoc NETworks (H-MANETs) are considered. H-MANETs are composed of nodes with different transmission range. The authors propose an improvement of AODV protocol called AMAODV (Adaptative Mobility aware AODV). This protocol is based on new metric combine more routing metrics (distance, relative velocity, queue length and hop count) between each node and one hop neighbor. Which permits to avoid losing route.
