Packet size based routing for route stability in mobile ad-hoc networks

In Mobile Ad-hoc Networks (MANET), wireless links' capability varies in transporting data packets on their sizes. Two main reasons are topology changes due to mobility and higher bit error rate on wireless links over longer distances. Many researches have been carried out to adopt more reliable links in making stable end-to-end routes. However, these approaches 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 select wireless links based on their capability of transporting different sizes of data packets and construct end-to-end routes accordingly. Our scheme is stateless and do not rely on the underlying layers. Extensive simulation shows the validity of our concept and highlights the efficiency achieved by our proposal.
