A Reliable Cluster-based Routing Algorithm for MANET

Abstract

It is known that conventional reactive routing protocols in Mobile Ad-hoc Networks (MANETs) decrease the packet delivery rate (PDR) in high-mobility and -traffic environments. This is because temporary congestion occurs due to control packets flooding the route establishment and the route break in long route communications. Generally, clustering is an effective method for improving the capacity for dealing with node mobility. However, current clustering methods have the long route communication problem described above. Therefore, we propose a reliable clustering method, called the “Cluster-by-Cluster routing method” , for reining in the emergence of long route communications by cascading short route communications. Furthermore, we implement our proposed method on Dynamic Source Routing (DSR), which is a representative reactive routing protocol, and evaluate the effectiveness with a computer simulation.
