  Abstract

In mobile ad hoc networks (MANETs), nodes use hello messages to detect neighbour nodes and to maintain link connectivity. In a typical MANET routing, a node broadcasts hello messages at a fixed interval. However, a fixed hello interval causes a long delay of neighbour discovery (if hello intervals are excessively long) or greater bandwidth wastage due to unnecessary protocol overhead (if hello intervals are overly short). In this study, we define a link change ratio based on the information of neighbour nodes and investigate the relationship between the link change ratio and the hello interval in terms of total throughput. The simulation results demonstrate that the link change ratio normally increases as the hello interval increases. However, hello intervals that maximize the network throughput exhibit a constant range of link change ratios, even though node mobility changes. Using this result, we propose an adaptive hello control scheme based on the link change ratio. Simulation results confirm that the proposed scheme can significantly enhance the total network throughput compared with existing adaptive schemes using a link change rate.
