Description
Summary:Node mobility affects routing in terms of robustness and efficiency, as it may lead to frequent link breaks that are not always automatically detected at a protocolar level. In user-centric environments, nodes are characterized by dynamic mobility behavior because they are devices carried or controlled by humans. We propose routing metrics aimed at making routing more robust through consideration of node spatial correlation for successor node. We have validated our metrics in Ad hoc On-Demand Distance Vector (AODV) routing protocol using Network Simulator 2. Results obtained show that our metrics increase multi-hop routing robustness in terms of path re-computation reduction.
