【正文】 方式如圖一所示。 the query chain is used to gather data from a number of interested/targeted sensor nodes. After receiving the chain information and the chain type, sensor nodes work independently for their datagathering task. The simulation results show that the AntChain scheme performs much better than PEGASIS and LEACH in terms of energy efficiency, lifetime, date quality and reliability. 利用 antchain算法，基站使用一種有效率的優(yōu)化方法 蟻群優(yōu)化法，形成一條信息鏈 。 (Batterysupplied sensor nodes need to consume energy for three main tasks: Sensing, putation and munication, among which munication often costs a significant portion of energy) 本文介紹了三種方法，一、 Heinzelman 提出的自適應聚類分層法 “LowEnergy Adaptive Clustering Hierarchy” (LEACH)，二、 PEGASIS改進 LEACH方法后提出的 PEGASIS方法，三、也就是本文提出的螞蟻鏈算法 (AntChain algorithm),通過比較三種方法的優(yōu)缺點，和仿真結(jié)果說明哪一種方法更好 — 效率高，節(jié)能，路徑最短等 。當基站建于傳感器節(jié)點附近的時候，仿真結(jié)果表明，我們稱之為螞蟻鏈 (antchain)的進化算法，在能量利用效率，數(shù)據(jù)完整性和存活時間方面遠優(yōu)于其他協(xié)議。摘要： 本文介紹了一種集中式的數(shù)據(jù)采集和通訊的無線傳感器網(wǎng)絡。無論傳感器網(wǎng)絡拓撲結(jié)構(gòu)產(chǎn)生任何微小改變，傳感器網(wǎng)絡器節(jié)點都能形成一條自適應的雙向鏈式結(jié)構(gòu)。(A WSN usually consists of a large number of sensor nodes. These tiny sensor nodes, often powered by battery, have the capabilities of sensing, municating, puting and power supplying.) 電池供電的傳感器節(jié)點，其消耗的能量主要用來完成三項任務：檢測信號，計算和通訊，其中通訊是最消耗能量的一項任務。 the simple unidirection AntChain is used for limite
