Embodiment Construction

[0030] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] Such as figure 1 As shown, the present invention has designed a routing protocol message forwarding method based on experience fitting in a delay-tolerant network, which is used to realize the forwarding of routing protocol messages in a delay-tolerant network. In the actual application process, it specifically includes the following steps:

[0032] Step 001. The source node uses the following formula according to the lifetime T of the target message:

[0033]

[0034] Obtain the maximum number of copies L of the target message corresponding to the first sending stage 1 , where P represents the target message forwarding rate expected by the user. In practical applications, the target message forwarding rate P expected by the user is greater than 90%, λ represents the average contact rate between nodes in the d...

Abstract

The invention relates to a routing protocol message forwarding method based on experience fitting in a delay-tolerant network, which overcomes the deficiencies in the prior art, and can solve the complexity of the copy allocation algorithm in the two-stage delay-tolerant network spray-waiting routing protocol based on the empirical fitting method High degree of problem, and can greatly reduce the calculation steps, thereby reducing the complexity of the algorithm, improve the efficiency of the experiment, and based on the empirical formula of the two-stage spray-waiting routing protocol close to the theoretical optimal, can make the message transmission overhead significantly reduce while maintaining a high delivery rate.

Description

technical field [0001] The invention relates to a routing protocol message forwarding method based on experience fitting in a delay-tolerant network, belonging to the technical field of routing in a mobile peer-to-peer network. Background technique [0002] A Mobile Delay Tolerant Network (MDTN) consists of a group of mobile devices, such as mobile phones or sensor units, that can communicate over a small range via a wireless protocol (such as Bluetooth). With the rapid popularization of various portable devices, various types of sensors are integrated in terminals such as tablets, smart phones, and vehicle-mounted sensing devices on the market, and the capabilities of sensing, computing, and communication are becoming stronger and stronger. Using the mobile sensing network composed of these portable devices, it is possible to sense opportunities in hotspot areas where human activities are frequent anytime, anywhere. This human-centered perception method constitutes an impo...
