| 摘 要： | 提出了一种基于时隙轮循的无线传感器网络MAC协议串音控制策略。此策略以簇结构组织网络,由簇头为簇内节点分配互不重叠的工作时隙,并以自带信令的方式来避免节点之间可能的串音。理论分析及仿真表明采用时隙轮循的串音控制策略有效地减少了节点间的串音,提高了无线传感器网络MAC协议的能量有效性。

| Abstract: | This paper proposes an overhearing control strategy based on time-slot round in wireless sensor networks.The strategy distributes time-slots to nodes roundly by cluster head,and uses in-channel signaling to avoid overhearing in wireless sensor networks.Analysis and simulation experiments show that the strategy is capable of reducing overhearing,improving energy-efficient and extending network life. |

| Keywords: | overhearing MAC protocol time-slot round energy-efficient |
