LAR routing stability protocol based on mobility prediction

Alongside advancements in communication technology, Ad Hoc networks have grown considerably in popularity. In high-relative-velocity environments, however, air nodes often have supersonic velocity but ground nodes are nearly stationary. In this case, traditional protocols do not satisfy the necessary link stability though this type of node usually has clear purpose or mission. To this effect, node activity can be forecast to a certain extent. In this study, a motion model was developed to describe aircraft flying in high-relative-velocity environments. We also investigated methods of maximizing link lifetime and network stability by designing an improved LAR1 protocol. MatLab simulation results showed that the proposed LAR1 protocol has superior performances in terms of link lifetime, but may increase the number of hops in data transmission.
