A Personalized Routing Scheme Selection System for Delay Tolerant Networks Oriented to Handheld Mobile Devices

Abstract

The invention belongs to the field of mobile network routing, and in particular relates to a delay-tolerant network personalized routing scheme selection system for handheld mobile devices. The invention includes: the opening module of the handheld mobile device receives an instruction from the user to enable the routing function; the inter-device information interaction module is used for information interaction between the handheld mobile device and the handheld mobile device; the user demand collection module receives the Flag from the opening module; device resources The perception module receives the Flag from the opening module; the DTN routing method acquisition module receives the Flag from the opening module; the DTN routing method filtering module receives the set of inter-device information storage from the inter-device information interaction module and the ROM from the DTN routing method acquisition module collection etc. In the present invention, the handheld mobile device uses the optional DTN routing method to communicate, and its application can reduce the resource overhead of the handheld device and improve the delivery rate of messages.

Description

technical field [0001] The invention belongs to the field of mobile network routing, and in particular relates to a delay-tolerant network personalized routing scheme selection system for handheld mobile devices. Background technique [0002] In recent years, handheld mobile devices have the characteristics of "small and light", "convenient communication" and "Internet access anytime, anywhere", which can always accompany users, making the mobile Internet show a spurt of development. However, there are still some areas where the network infrastructure is not perfect, featuring intermittent connections, high latency, and low delivery rates. In this environment, handheld mobile devices cannot complete information transmission through traditional networks, and it is necessary to use the "store-carry-forward" routing mode of Delay Tolerant Network (DTN, Delay Tolerant Network) to solve communication problems in this environment. Due to the popularity of handheld mobile devices ...

The paper "Delay Tolerant Network on AndroidPhones: Implementation Issues and Performance Measurements" (http: / / ojs.academypublisher.com / index.php / jsw / article / view / jsw091027132720) implements a bandwidth and battery Consumable DTN routing method, but it does not consider the individual needs of users

The paper "Bundle Protocol Implementation for Android Devices" (http: / / dl.acm.org / citation.cfm?id=2348606) designed the IBR-DTN routing scheme. IBR-DTN can run on mobile phones with version 2.3 , but does not provide users with personalized routing solutions

[0004] To sum up, although the current handheld mobile devices can use a certain fixed DTN routing mode to transmit data, the fixed DTN routing mode cannot fully meet the individual needs of different users
