無(wú)線通信網(wǎng)絡(luò)中的協(xié)作緩存管理
發(fā)布時(shí)間:2022-12-18 00:02
隨著各種智能終端的大規(guī)模普及和移動(dòng)數(shù)據(jù)流量的爆炸式增長(zhǎng),當(dāng)前無(wú)線網(wǎng)絡(luò)中的基礎(chǔ)設(shè)施和移動(dòng)設(shè)備面臨著容量受限的問題,在第五代(Fif th-ge neration,5G)移動(dòng)通信網(wǎng)絡(luò)中該問題將更加嚴(yán)峻。緩解該問題的最新方法是通過機(jī)會(huì)通信來卸載數(shù)據(jù)通信量一—協(xié)調(diào)多個(gè)網(wǎng)絡(luò)節(jié)點(diǎn)(如智能手機(jī)、筆記本電腦、基站等)實(shí)現(xiàn)緩存共享。由于協(xié)作緩存管理能夠提升網(wǎng)絡(luò)吞吐量并且減少通信開銷,因此無(wú)線通信網(wǎng)絡(luò)中的協(xié)作緩存管理成為最近的熱門研究課題。協(xié)作緩存策略在無(wú)線通信中發(fā)揮重要作用,本論文研究了以內(nèi)容為中心的移動(dòng)自組織網(wǎng)絡(luò)和設(shè)備到設(shè)備(device-to-device,D2D)通信中的協(xié)作緩存管理,F(xiàn)有文獻(xiàn)主要研究通過蜂窩網(wǎng)絡(luò)鏈路利用高速緩存和用戶關(guān)聯(lián)策略的聯(lián)合設(shè)計(jì)以及解決服務(wù)質(zhì)量(quality of service,QoS),較少考慮D2D傳輸設(shè)備的可用性。為解決此問題,本文提出了相應(yīng)的協(xié)同緩存管理及解決方案以防止用戶需求的冗余,并且展現(xiàn)了內(nèi)容流行度分布性能的高度提升。本論文具體研究總結(jié)如下。1)為了優(yōu)化以內(nèi)容為中心的無(wú)線自組織網(wǎng)絡(luò)中的緩存配置,提出了一種協(xié)作組緩存策略,其中以緩存命中概率作為優(yōu)化緩存配置目...
