Autonomous Congestion Control in Delay-Tolerant Networks

摘要: Congestion control is an important feature that directly affects network performance. Network congestion may cause loss of data or long delays. Although this problem has been studied extensively in the Internet, solutions for Internet do not apply readily to challenged environments such as Delay Tolerant Networks (DTN) where end-to-end connectivity exist continuously and latency can be high. In DTN, rate feasible. This calls mechanisms decisions made autonomously with local information only. We use economic pricing model propose a rule-based mechanism each router decide on whether accept bundle (data) based available storage value risk accepting (derived from historical statistics). Preliminary experimental results show protect routers resource depletion without data.
