Summary: 
In Mobile Ad-hoc Networks (MANET), transportation capability of wireless links' varies according to the size of the packets they transport. This instability, which is more acute in long links, has received little attention in the stabilizing schemes proposed so far for MANET. A lot of research has been carried out to utilize more reliable links in making end-to-end routes to avoid frequent route failures and realize higher packet delivery ratio. However, these approaches mainly consider the availability of a link over time and depend on link history which is difficult to acquire in highly dynamic systems. In this paper, we present an easy-to-implement but efficient method to find suitable end-to-end routes that are capable of transporting different sizes of the application data packets. Our scheme is stateless and does not rely on the underlying data link and physical layers. An extensive simulation shows the validity of our concept and highlights the improvement achieved by our proposal.
