Abstract
In this study we propose a rate control algorithm for intermittently connected networks ICNs a type of delay/disruptiontolerant network The different characteristics of ICNs compared with traditional TCP/IP networks lead to problems that do not occur in legacy networks such as network partitioning long and varying delays high loss probability and asymmetric data transmission rates To overcome these issues much recent research has been carried out However while the results have helped achieve smooth communication between nodes there are still certain shortcomings For example if many messages are input by the nodes in a network these schemes do not work well To resolve this problem we propose a novel sending rate control algorithm in an additive increase/multiplicative decrease manner To detect network congestion we measure the receiving rate oneway delay and average number of copies When the measured receiving rate increases the congestion window cwnd also increases otherwise cwnd decreases The simulations show that the proposed algorithm can adjust the sending rate of nodes to avoid network congestion and provide a fair share of the network for the nodes
