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.

目前提出的拓撲控制算法一般是針對網(wǎng)絡(luò)拓撲的某一方面進行了優(yōu)化設(shè)計。文獻[2]中算法未考慮網(wǎng)絡(luò)負載平衡、網(wǎng)絡(luò)的整體能耗水平和網(wǎng)絡(luò)中單一節(jié)點能量狀態(tài)帶來的影響；文獻[3]最小生成樹算法(MSTP)和文獻[4]鄰近圖算法(DRNG)都忽略了多跳中繼區(qū)域問題，從而增加了節(jié)點的能耗；文獻[5]中算法易形成節(jié)點孤島，影響網(wǎng)絡(luò)的連通性，無法保障數(shù)據(jù)傳送的可靠性[5-6]；文獻[7]算法未考慮通信開銷和網(wǎng)絡(luò)的魯棒性問題。本文通過對多跳中繼區(qū)域的分析，設(shè)計一種智能拓撲控制算法RBTC(Relay-Based Topology Control Algorithm)。通過分析得出，該算法不僅能消除不合理多跳，而且降低最小路徑損耗和發(fā)射功率。
