Abstract: Reducing the energy consumption of wireless sensor nodes is the focus of intelligent algorithm research. This paper studies the power control algorithm and finds that the existing algorithm ignores the problem of multi-hop relay area, which increases the energy consumption of nodes. Therefore, this paper proposes a low-power intelligent topology control algorithm. The algorithm collects the feedback information of each node′s power consumption, forms the topology of the largest neighboring node, traverses all neighboring nodes, and selects the path with the least energy consumption. The algorithm can eliminate unreasonable multi-hop, reduce the maximum transmission power of each node, and maintain the connectivity of the whole network. In theory, the algorithm has certain practical application value.
Key words : wireless senor network;RBTC;node degree;low power consumption

    隨著人工智能及智能制造在工業(yè)領(lǐng)域、軍事領(lǐng)域、環(huán)境監(jiān)測等方面的廣泛應(yīng)用,新型分布式無線傳感器由于無需接線、超低能耗、使用方便,正變得越來越廣泛。如何在滿足網(wǎng)絡(luò)覆蓋度和連通度的前提下,節(jié)省無線傳感器節(jié)點(diǎn)能量、形成高效的數(shù)據(jù)轉(zhuǎn)發(fā)拓?fù)浣Y(jié)構(gòu),是拓?fù)淇刂扑惴ㄑ芯康闹攸c(diǎn)[1]。
