Multipath Routing Issues in Virtual Private Ad Hoc Networks

In this paper we discuss the impact of proactive routing in comparison with a reactive routing approach in an environment where multiple communication technologies are used simultaneously. Therefore the Virtual Private Ad Hoc Networking platform will be introduced and used. A simulation environment is created and used to illustrate the outcomes with a simple scenario. Although many papers have been published comparing proactive and reactive routing protocols, this paper focusses on the impact on the VPAN platform with its two-level hierarchical architecture and nodes joining and leaving clusters.
