設(shè)備到設(shè)備（D2D）通信作為一種重要的新技術(shù),對(duì)未來(lái)網(wǎng)絡(luò)技術(shù)如5G和物聯(lián)網(wǎng)（IoT）有著重要的推動(dòng)作用。其泛在通信的特點(diǎn)可以有效解決流量爆炸問(wèn)題,并有望實(shí)現(xiàn)超低時(shí)延通信。盡管有上述優(yōu)勢(shì),在具體的網(wǎng)絡(luò)應(yīng)用場(chǎng)景中,傳統(tǒng)的D2D在緩存和轉(zhuǎn)發(fā)策略方面仍然存在著有效性與可靠性的問(wèn)題。因此,本文提出基于命名數(shù)據(jù)網(wǎng)絡(luò)（NDN）的D2D架構(gòu)。在此基礎(chǔ)之上,本文提出了基于勢(shì)能的路由（PBR）策略。路由勢(shì)能由內(nèi)容的質(zhì)量以及節(jié)點(diǎn)之間的接近程度來(lái)定義。PBR根據(jù)每個(gè)節(jié)點(diǎn)的路由勢(shì)能做出路由決策,進(jìn)而找到從用戶到可用內(nèi)容副本之間的最佳路徑。仿真結(jié)果表明,與傳統(tǒng)的解決方案相比,該方案可以明顯提升平均響應(yīng)延遲和緩存命中率方面的性能。
