【摘要】：智能終端設(shè)備在近幾年得到了廣泛的發(fā)展,其普及率逐漸提高,由于智能終端設(shè)備提供更好的操作系統(tǒng)支持,終端可以運(yùn)行功能更加豐富的應(yīng)用程序。用戶在體驗(yàn)豐富多樣的移動(dòng)應(yīng)用的同時(shí)也帶來(lái)了移動(dòng)數(shù)據(jù)業(yè)務(wù)需求的爆炸式增長(zhǎng)。這一現(xiàn)狀給蜂窩網(wǎng)絡(luò)帶來(lái)了巨大的業(yè)務(wù)壓力,在一些移動(dòng)節(jié)點(diǎn)密集的區(qū)域,網(wǎng)絡(luò)的性能會(huì)因?yàn)榇罅恳苿?dòng)設(shè)備的數(shù)據(jù)業(yè)務(wù)請(qǐng)求而下降。為了分流網(wǎng)絡(luò)數(shù)據(jù)業(yè)務(wù),提升網(wǎng)絡(luò)吞吐量,有必要引入健壯可靠的負(fù)載分流機(jī)制來(lái)提高網(wǎng)絡(luò)的整體性能。 在移動(dòng)節(jié)點(diǎn)密集區(qū)域,節(jié)點(diǎn)之間的相遇頻率較高,彼此之間往往表現(xiàn)一定的社會(huì)關(guān)系。在這樣的場(chǎng)景下可以引入機(jī)會(huì)網(wǎng)絡(luò),利用節(jié)點(diǎn)之間的協(xié)作傳輸分流移動(dòng)數(shù)據(jù)。本文將傳統(tǒng)集中式網(wǎng)絡(luò)與機(jī)會(huì)網(wǎng)絡(luò)融合,構(gòu)建混合網(wǎng)絡(luò)架構(gòu)。在混合網(wǎng)絡(luò)架構(gòu)的基礎(chǔ)上,本文設(shè)計(jì)混合傳輸路由協(xié)議,采用“機(jī)會(huì)傳輸為主,中心補(bǔ)傳為輔”的方針。路由算法在PRoPHET的基礎(chǔ)上引入傳輸空間和節(jié)點(diǎn)信譽(yù)概念,在保證數(shù)據(jù)交付率的同時(shí)有效控制副本數(shù)量。 由于節(jié)點(diǎn)往往表現(xiàn)一定的自私性,為了保證路由策略有效執(zhí)行,本文針對(duì)混合網(wǎng)絡(luò)架構(gòu)設(shè)計(jì)了基于信譽(yù)的激勵(lì)機(jī)制。與傳統(tǒng)激勵(lì)機(jī)制不同,本文設(shè)計(jì)的激勵(lì)機(jī)制綜合考慮節(jié)點(diǎn)的社會(huì)屬性,主要工作集中在量化節(jié)點(diǎn)的關(guān)聯(lián)屬性上。通過(guò)構(gòu)建量化模型,優(yōu)化了信譽(yù)更新因子,在信譽(yù)更新過(guò)程中,采用節(jié)點(diǎn)主動(dòng)更新和被動(dòng)更新兩種方式,優(yōu)化了更新算法,在有效懲罰自私節(jié)點(diǎn)同時(shí),維護(hù)邊緣節(jié)點(diǎn)的利益,保證網(wǎng)絡(luò)的公平性。 本文還設(shè)計(jì)了針對(duì)混合網(wǎng)絡(luò)的仿真平臺(tái),采用模塊化設(shè)計(jì),具有很強(qiáng)的擴(kuò)展性。其中,平臺(tái)中的節(jié)點(diǎn)單元可以理解為移動(dòng)終端也可以理解為基站等中心設(shè)備。節(jié)點(diǎn)類中私有成員內(nèi)容豐富,能夠?yàn)槁酚赡K提供豐富的網(wǎng)絡(luò)數(shù)據(jù)支持,目前仿真平臺(tái)能夠順暢運(yùn)行Epidemic、 CORE等經(jīng)典路由協(xié)議。
[Abstract]:Intelligent terminal equipment has been widely developed in recent years, its popularity has gradually increased, because intelligent terminal devices provide better operating system support. Terminals can run more functional applications. While users experience rich and diverse mobile applications, they also bring explosive growth in the demand for mobile data services. This situation has brought a huge industry to cellular networks. Pressure. In some areas where mobile nodes are dense, the performance of the network will decline because of a large number of data service requests from mobile devices. In order to split the network data services, improve the network throughput. It is necessary to introduce a robust and reliable load shunt mechanism to improve the overall performance of the network. In the mobile node dense area, the meeting frequency of the nodes is high, and the social relations between each other are often certain. In such a scenario, the opportunity network can be introduced. In this paper, the traditional centralized network and opportunity network are combined to construct the hybrid network architecture. Based on the hybrid network architecture, this paper designs the hybrid transport routing protocol. The routing algorithm introduces the concepts of transmission space and node reputation on the basis of PRoPHET. Ensure the data delivery rate while effectively controlling the number of copies. In order to ensure the effective implementation of routing strategy, this paper designs a credit-based incentive mechanism for hybrid network architecture, which is different from the traditional incentive mechanism. The incentive mechanism designed in this paper takes into account the social attributes of nodes, and the main work is focused on the correlation attributes of quantized nodes. By constructing a quantitative model, the reputation update factor is optimized, and in the process of reputation updating. Both active and passive updating methods are adopted to optimize the updating algorithm to maintain the interests of the edge nodes and ensure the fairness of the network while punishing the selfish nodes effectively. This paper also designed a simulation platform for hybrid networks, using modular design, which has a strong scalability. The node unit in the platform can be understood as a mobile terminal or a central device such as a base station. The private members in the node class are rich in content and can provide abundant network data support for the routing module. At present, the simulation platform can run the classic routing protocols such as Epidemicand CORE smoothly.
