An adaptive hierarchical extension of DSR: the cluster source routing

This paper presents a cluster-based extension of the DSR protocol called cluster source routing (CSR). The proposed approach improves the scalability of DSR in high-density and low-mobility networks. The originality of our proposal is an adaptive use of DSR and CSR routing modes according to network density and node mobility in order to produce less overhead and perform efficient routing. Thus, the DSR-CSR protocol achieves enhanced performance over a broader {network density, node mobility} domain as shown by simulations.
