    摘要:

    結(jié)合溫室測(cè)控系統(tǒng)特點(diǎn)，構(gòu)建無線傳感網(wǎng)絡(luò)空間結(jié)構(gòu)和時(shí)序,，以達(dá)到降低和均衡節(jié)點(diǎn)能耗,，延長溫室無線傳感網(wǎng)絡(luò)生命周期的目的,。在網(wǎng)絡(luò)空間結(jié)構(gòu)上,，以溫室上部能量充裕的可移動(dòng)匯聚節(jié)點(diǎn)為樞紐,，與能量有限的子節(jié)點(diǎn)動(dòng)態(tài)地構(gòu)成星形無線網(wǎng)絡(luò),；在網(wǎng)絡(luò)時(shí)序上,，使子節(jié)點(diǎn)只在連接時(shí)段通信，其余時(shí)間休眠,。通過對(duì)子節(jié)點(diǎn)最大通信半徑和匯聚節(jié)點(diǎn)最小通信半徑的分析,，解決了網(wǎng)絡(luò)的連通問題。

    Abstract:

    Combined with the characteristics of greenhouse measurement and control system, the spatial structure and time sequence of wireless sensor network were constructed to reduce and balance node energy consumption to prolong network lifetime. As to the network spatial structure, each mobile sink node located at the upper side of greenhouse, could provide abundant energy. Taking the mobile sink nodes as hinges, the limited energy sub-nodes made up of the stelliform wireless network. As to the network time sequence, the sub-nodes were active only in communication duration and sleeping in other phases. The maximal communication radius of sub-nodes and the minimal communication radius of sink nodes were analyzed to solve the problem of network connectivity.
