| 摘 要： | 分析了水下无线传感器网络（WSNs）中单链路发射功率和距离与频率的关系,提出一种跨层的集中式调度方法,AP（access point）在网络中通过广播信标的形式收集估计各节点的时延和距离信息,在MAC层考虑水下链路延迟特点,对各链路进行调度减少冲突;节点在物理层通过自适应地改变节点发射功率和发射频率,减少能耗.仿真结果表明：所提方案在节省系统能量消耗的同时,能够减少碰撞,提高系统吞吐量.

| Abstract: | Relationships between distance, transmit power and frequency of single link in underwater wireless sensor networks（UWSNs） are analyzed, a centralized scheduling method based on cross-layer is proposed, access point（AP） through broadcasting beacon collect and estimate information of delay and distance of each node, in MAC layer, AP schedules every link by considering delay features of underwater link to avoid collision;in physics layer, transmitting power and frequency of nodes are changed adaptively to decrease energy consumption. Simulation results show that the proposed scheme can decrease collision and improve throughput as well as save energy consumption. |
