Inter-domain routing and name resolution using border nodes

Abstract

Stable and reliable communication is essential in disaster scenarios. Mobile Ad hoc Networks (MANETs) provide a network that is fast to setup and that works independently of possibly damaged infrastructure. This is important during disaster rescue and recovery missions. But single isolated MANETs are able to cover only a limited area. Therefore, it is necessary to interconnect these individual networks in order to provide communication throughout the whole disaster area. The resulting network is heterogeneous because each MANET might employ different routing protocols as well as other underlying network technologies. In this paper, we present an approach to couple such heterogeneous networks using multihomed border nodes. We show how network-wide route discovery and name resolution is achieved and also propose a solution to address possible collisions in such environments.
