Cluster-based location routing algorithm for inter-vehicle communication

We consider a motorway environment with associated high mobility and compare and contrast position-based and non-position-based routing strategies in reactive ad-hoc protocols. The performances of dynamic source routing (DSR) and ad-hoc on-demand distance vector routing (AODV), for non-positional algorithms, and cluster-based location routing (CBLR), for positional algorithms, are considered. First, for small-scale networks, we have validated our simulation model with the results of a test bed. Then, through simulations, our model is compared with two prominent reactive routing algorithm models for large-scale networks: AODV and DSR. Finally, vehicle mobility on a motorway using a microscopic traffic model developed in OPNET is used to evaluate average route discovery (RD) time, end-to-end delay (EED), routing load, routing overhead, overhead, and delivery ratio.
