“…Some strategies selectively discard messages according to the message properties such as the survival time (Drop First) and the location in the queue (Drop Tail), thereby maintaining the storage capacity of the node [10,11]. The core idea of pre distribution and quota control method is to adjust and optimize the performance by measuring the global network state, and then ease the network congestion [12].…”

Abstract-Delay Tolerant Network (DTN) is a kind of wireless network with limited resources and often occurs congestion. The effective cache management can make full use of the network resources and reduce the network congestion. Therefore, aiming at the deficiency of the current research of cache management, this paper puts forward a kind of cache management strategy based on node status. With the knowledge of statistical analysis and control, the message queue and transmission rate are managed dynamically by detecting node activity and load. The experimental results show that, under the cache management, the network congestion was obviously reduced, and the utilization rate of resources has been improved, and the communication quality of the DTN is guaranteed.
