延遲容忍網(wǎng)絡(luò)中一種基于概率接納和丟棄的擁塞控制算法
[Abstract]:The intermittent connectivity of links and the lack of stable end-to-end paths lead to the "storage-port-to-forward" approach to ensure the arrival rate of messages in delay tolerance networks (delay tolerant network). However, due to the limitation of network resources, a large number of message replicas generated by this forwarding mode will cause huge resource consumption and eventually lead to network congestion. A congestion control algorithm PAD. based on probabilistic admission and discard (probabilistic acceptance and drop,PAD is proposed. The algorithm combines queue length and input / output rate to detect congestion. Each node determines the probability of receiving and dropping messages according to the current congestion state, thus achieving lower overhead and higher message arrival rate. In addition, the continuous time Markov chain of message replicas is constructed based on the birth and death model, and the message arrival rate is analyzed theoretically. The theoretical analysis and simulation results show that compared with other algorithms, the PAD algorithm can significantly increase the message arrival rate by more than 130% while ensuring lower network overhead and shorter end-to-end delay.
