为降低组网成本并保证UWSNs(underwater wireless sensor networks)对监测区域的高覆盖率,提出一种三维分层混合部署策略.为实现自组网并完成信息的高效传递,提出一种与部署策略相适配的垂直分簇路由算法.该算法可利用节点位置、能量等信息,周期性地将网络划分成多跳垂直簇,并建立簇内节点间的路由路径,借助反馈信息完成网络空洞的监测和处理.仿真结果表明,所提出的设计方法能够大幅降低组网成本,而且能显著提升网络在数据包投递率、能量利用效率等方面的性能表现.
In order to reduce networking costs and ensure high coverage of UWSNs in monitoring area, a three-dimensional layered hybrid deployment strategy is proposed.In order to realize ad hoc network and achieve efficient information delivery, Adaptive vertical clustering routing algorithm.Using the information of node location and energy, the algorithm divides the network into multi-hop vertical clusters periodically and establishes the routing path between nodes in the cluster, and completes the network hole with feedback information Monitoring and processing.The simulation results show that the proposed design method can significantly reduce networking costs and can significantly improve network performance in data packet delivery rate and energy utilization efficiency.
