    摘要:

    水声传感器网络设计的其中一个目标就是提供节点间可靠通信的同时,能量消耗最小化。通过构造简化的场景,参考海洋中水声信号的吸收损失、传感器节点的参数以及实际环境参数推算出水声传感器网络分别在集中式拓扑结构和多跳式拓扑结构下的能量消耗模型。通过仿真得出:在短距离通信时采用中继节点实际上浪费了能量,采用集中式拓扑结构能量效率较高;而在长距离通信时,采用多跳拓扑结构选择合适的中继节点个数有优越的能量效率。

    Abstract:

    One of the aims to design the underwater acoustic sensor networks is to supply the reliable communications between nodes and minimize the energy consumption as well. According to the absorption loss of underwater acoustic signals in the ocean and the parameters of the components, parameter of sensor node and actual surroundings, it also states the methods of forming the energy consumption model of the underwater sensor networks in the structure of centralized topology and Multi-hop topology.Application of the relay in fact a waste of energy. In short-range communication, however adopt the centralized topology structure have high energy efficiency. In long-range communication application of Multi-hop topology and choose the suitable number of nodes have the high energy efficiency. At last, that result is validated by simulation.
