A Stable Linked Structure Flooding for Mobile Ad Hoc Networks with Fault Recovery
Résumé
Efficient message dissemination in ad hoc networks can be fostered by exploiting stable (sub-)structures. By efficient we mean low network resource usage regarding reachability. In this paper we build a hierarchical protocol. We first create single-hop clusters among stable-connected devices. On top of those clusters, we further determine inter-cluster relays (ICR), finally providing an overall stable-connected structure. Our proposed stable linked structure flooding (SLSF) protocol efficiently disseminates data among stable nodes. Additional fault recovery mechanisms are employed to compensate for local intermittent node failures if needed. The experiments show that our approach increases flooding performances with a low bandwidth usage. Furthermore SLSF remains very efficient with or without the fault recovery mechanism that provides robustness.
