8、再下降，LPL也不再有跳 變。L-MAC節(jié)點(diǎn)平均能耗也約為單播時(shí)的兩倍。 由于無(wú)線傳感器網(wǎng)絡(luò)具有能量受限的特點(diǎn)，許多的研 究者都試圖使用一種新的MAC協(xié)議來(lái)改善其節(jié)能性能。但 迄今為止，還沒(méi)有一種MAC協(xié)議可以作為通用的標(biāo)準(zhǔn)。我 們認(rèn)為傳感器網(wǎng)絡(luò)是應(yīng)用相關(guān)的網(wǎng)絡(luò)，不存在一個(gè)適用于 所有傳感器網(wǎng)絡(luò)的MAC協(xié)議，應(yīng)該根據(jù)不同的應(yīng)用來(lái)選擇 不同的協(xié)議類(lèi)型來(lái)設(shè)計(jì)無(wú)線傳感器網(wǎng)絡(luò)MAC協(xié)議。 參考文獻(xiàn) 1 J.
