面向能量收集無(wú)線傳感器網(wǎng)絡(luò)中繼預(yù)選擇和資源分配研究
發(fā)布時(shí)間:2024-12-21 02:01
無(wú)線通信和電子技術(shù)的進(jìn)步使得低成本、低功耗、多功能傳感器節(jié)點(diǎn)性能得到極大的提高,這些微小的傳感器節(jié)點(diǎn)由傳感、數(shù)據(jù)處理和通信組件組成,無(wú)線傳感器網(wǎng)絡(luò)由大量的傳感器節(jié)點(diǎn)組成,上述特性確保了無(wú)線傳感器網(wǎng)絡(luò)被廣泛應(yīng)用在各個(gè)領(lǐng)域。在軍事上,無(wú)線傳感器網(wǎng)絡(luò)的快速部署、自組織和容錯(cuò)特性使其成為一種非常有前途的傳感技術(shù),用于軍事指揮、控制、通信、計(jì)算、情報(bào)、監(jiān)視、偵察和目標(biāo)系統(tǒng);在健康方面,無(wú)線傳感器節(jié)點(diǎn)可以用于監(jiān)測(cè)病人和幫助殘疾病人,用于協(xié)助醫(yī)生對(duì)病人準(zhǔn)確診斷治療;在家庭方面,用于家庭安防報(bào)警系統(tǒng),家庭數(shù)據(jù)采集,家電及家庭電子設(shè)備的控制滿足人們的美好生活需求;在工業(yè)安全方面,可用于危險(xiǎn)的生產(chǎn)環(huán)境,可以隨時(shí)監(jiān)控工作環(huán)境的安全狀況,為工作人員的安全提供保障;在智能交通方面,可以為智能交通系統(tǒng)的信息采集和信息傳輸提供一種有效手段,從根本上解決困擾現(xiàn)代交通的問(wèn)題;在生態(tài)監(jiān)測(cè)和災(zāi)害預(yù)警方面,用于監(jiān)測(cè)自然環(huán)境污染情況和提前預(yù)警自然災(zāi)害的發(fā)生;其他一些商業(yè)應(yīng)用領(lǐng)域包括管理庫(kù)存、監(jiān)視產(chǎn)品質(zhì)量和運(yùn)輸監(jiān)測(cè)。無(wú)線傳感器網(wǎng)絡(luò)無(wú)法像有線那樣提供穩(wěn)定的能量,在這些領(lǐng)域的廣泛應(yīng)用,信息的采集和傳輸會(huì)消耗大量的能量。目前,在解決耗能...
