Abstract

The present invention provides a method and device for improving the end-to-end delay of a hysteresis-tolerant network based on a similar behavior model. The method includes: mapping the application scene of the hysteresis-tolerant network on a map, and dividing the map into regions; Record the visit frequency of each node in the tolerance network to each area within the initialization time, and each node retains the weight value vector table of all areas; obtain the node pair where two nodes in the tolerance network enter the communication range of the other party, The node pair includes two nodes that enter the communication range of the other party; enter the distribution stage of the node pair; judge whether there is a node in the node pair whose message copy number is 1, and if so, enter the waiting stage. According to the solution of the present invention, the effects of high message delivery probability and reduced delivery delay in the tolerant network (DTN) can be obtained.

Description

technical field [0001] The invention relates to the field of hysteretic network (DTN), in particular to a method and device for improving end-to-end time delay of a hysteretic network based on a similar behavior model. Background technique [0002] Delay-tolerant network (DTN), instant delay tolerant network, is a general message-oriented and reliable overlay network architecture proposed by Kevin et al. in 2003. It is an overlay network located on top of a regional network. Such as figure 1 shown. It can be applied to limited network environments such as IPN, wireless sensor networks, and vehicle networks. It is mainly a solution for end-to-end connections and node resources with limited time. It is suitable for military, aerospace communications, disaster recovery, emergency rescue and other fields. Information interaction provides powerful scientific theory and technical support. However, network disconnection often occurs in hysteresis-tolerant networks, resulting in ...
