認(rèn)知無(wú)線電網(wǎng)絡(luò)中基于博弈論的合作頻譜感知
發(fā)布時(shí)間:2020-12-17 09:06
當(dāng)前,新無(wú)線設(shè)備的增長(zhǎng)增加了資源的稀缺性,而認(rèn)知無(wú)線電網(wǎng)絡(luò)為頻譜需求的擴(kuò)大提供開創(chuàng)性的答案。本文的主要思想是頻譜傳感的概念,它包含對(duì)主要用戶存在檢測(cè),因?yàn)橛绊懴到y(tǒng)如陰影、空間多樣性和多路徑等現(xiàn)象,下一個(gè)關(guān)鍵概念是合作,即所有用戶相互交互,以便檢測(cè)以前所有現(xiàn)象的效果,最后是博弈理論的概念,它呈現(xiàn)社會(huì),經(jīng)濟(jì)或任何類型的問(wèn)題外推成博弈,在這種情況下,基于合作決策是比較合適的。研究的重點(diǎn)是用戶對(duì)具有多個(gè)SU和多個(gè)主要用戶的認(rèn)知無(wú)線電網(wǎng)絡(luò)中的協(xié)同頻譜傳感和接入策略。該方法提出每個(gè)用戶根據(jù)自己的業(yè)務(wù)需求,與其他用戶共同決定接入和感知的信道,另外還可以決定接入哪個(gè)信道。當(dāng)用戶沒(méi)有數(shù)據(jù)要傳輸時(shí),可以節(jié)省能量以備將來(lái)傳輸。首先,本研究探討了基于流量需求的合作策略,即每個(gè)用戶在確定的時(shí)間跨度中感知一個(gè)通道。該聯(lián)盟具有不可轉(zhuǎn)讓的實(shí)用程序,其中所有用戶都會(huì)獲得與聯(lián)盟對(duì)應(yīng)的值,該值將用于計(jì)算吞吐量和能源效率。在這種情況下,聯(lián)盟組建是一個(gè)高度復(fù)雜的問(wèn)題,很難使用,為了克服這種復(fù)雜性,提出了一種新的聯(lián)盟組建算法。結(jié)果表明,該算法具有高能效的高通量。然后,通過(guò)在整個(gè)傳感時(shí)間中感應(yīng)多個(gè)通道,提高了策略復(fù)雜性,從而擴(kuò)展了...
