Evaluation of Queueing Policies and Forwarding Strategies for Routing in Intermittently Connected Networks

摘要: Delay tolerant networking (DTN) and more specifically the subset known as intermittently connected networking, is emerging a solution for supporting asynchronous data transfers in challenging environments where fully end-to-end path between source destination may never exist. Message delivery such networks enabled via scheduled or opportunistic communication based on transitive local connectivity among nodes influenced by factors node mobility. Given inherently store-and-forward nature of DTN architecture, choice buffer management policies message forwarding strategies can have major impact system performance. In this paper, we propose evaluate different combinations queueing networks. We show that probabilistic routing approach along with correct policy strategy result much performance improvements terms delivery, overhead delay.
