【摘要】：為了減少容延網(wǎng)絡(luò)的資源開銷,研究者提出了單副本轉(zhuǎn)發(fā)路由算法.研究發(fā)現(xiàn),這些轉(zhuǎn)發(fā)算法導(dǎo)致節(jié)點(diǎn)流量負(fù)載極度不均衡,使得那些連接度較大的節(jié)點(diǎn)產(chǎn)生了擁塞.針對該問題,提出了一種基于接收閾值的擁塞控制機(jī)制,可以有效降低節(jié)點(diǎn)擁塞.該機(jī)制使每個(gè)DTN(delay tolerant network)節(jié)點(diǎn)根據(jù)自身的擁塞狀況動(dòng)態(tài)調(diào)整自己的擁塞控制機(jī)制,而且該機(jī)制獨(dú)立于節(jié)點(diǎn)所運(yùn)行的轉(zhuǎn)發(fā)路由算法,不影響路由算法對中繼節(jié)點(diǎn)的選擇,具有很好的普適性.為了驗(yàn)證所提出機(jī)制的有效性,將該擁塞控制機(jī)制與現(xiàn)有的SimBet路由算法加以結(jié)合,提出了具有擁塞控制功能的SimBetCC算法.實(shí)驗(yàn)結(jié)果表明,SimBetCC算法在取得很好的擁塞控制的前提下,其遞交率和遞交時(shí)延等性能方面均優(yōu)于具有擁塞控制功能的FairRoute路由算法.
[Abstract]:In order to reduce the resource overhead of the delay network, the researchers proposed a single copy forwarding routing algorithm. It is found that these forwarding algorithms cause the extreme unbalance of the node traffic load, which makes the nodes with larger connectivity. A congestion control mechanism based on the receiving threshold is proposed, which can effectively reduce the congestion. Node congestion. This mechanism makes each DTN (delay tolerant network) node dynamically adjust its congestion control mechanism according to its own congestion, and the mechanism is independent of the forwarding routing algorithm run by the node. It does not affect the routing algorithm for the selection of relay nodes. It has good universality. In order to verify the effectiveness of the proposed mechanism By combining the congestion control mechanism with the existing SimBet routing algorithm, the SimBetCC algorithm with congestion control function is proposed. The experimental results show that, under the premise of good congestion control, the SimBetCC algorithm is superior to the FairRoute routing algorithm with congestion control function in the performance aspects of the delivery rate and submission delay.
