【摘要】：針對間斷連接無線網(wǎng)絡(luò)節(jié)點(diǎn)能量受限特性,提出一種帶有動態(tài)反饋的自適應(yīng)異步節(jié)能機(jī)制,以解決節(jié)點(diǎn)在空閑偵聽中能耗過大的問題;并在此基礎(chǔ)上,設(shè)計(jì)了一種能夠根據(jù)網(wǎng)絡(luò)通信錯(cuò)失率和節(jié)點(diǎn)能耗動態(tài)反饋調(diào)整的占空比機(jī)制,以有效延長生命周期,提升網(wǎng)絡(luò)的投遞性能。數(shù)值結(jié)果表明,與同類自適應(yīng)節(jié)能機(jī)制相比,所提機(jī)制能夠在不損失網(wǎng)絡(luò)投遞性能的情況下,極大限度地延長網(wǎng)絡(luò)和節(jié)點(diǎn)的生命周期。
[Abstract]:An adaptive asynchronous energy saving mechanism with dynamic feedback is proposed to solve the problem that nodes consume too much energy in idle listening. A duty cycle mechanism which can be adjusted according to network communication miss rate and node energy consumption dynamic feedback is designed in order to prolong the life cycle effectively and improve the delivery performance of the network. Numerical results show that compared with the similar adaptive energy saving mechanism, the proposed mechanism can greatly prolong the lifetime of the network and nodes without losing the network delivery performance.
