考虑水流影响的水下传感器网络移动算法研究*

随着世界各国海洋开发和海洋军事的飞速发展，水下传感器网络成为一个新的研究热点，其中失效补偿和高效节能是水下传感器网络研究的重要问题。水声通信的特点使得移动节点在水下传感器网络中得到较为广泛的使用，以其作为失效补偿和提高覆盖效率的有效手段。为了减小移动节点的能耗，改进了现有的移动部署方案，提出一种新的水下传感节点移动算法，在移动路径规划时充分利用水流和重力、浮力的影响来减少节点的移动能量。数值计算和仿真结果表明，本算法有效节省了移动节点的能量消耗，验证了其有效性和正确性。

Research of underwater mobile sensor network algorithm based on water flow

With the development of ocean exploitation and sea military technology all over the world, underwater sensors network (UWSN) has become a very recent network topic. Since very few years, it attracts a growing interest from the network community. In the UWSN research area it is a key problem about how to recover sensing areas and decrease energy consuming of the network. As a kind of widely used devices, the mobile nodes such as AUVs can recover sensing areas and increase covering efficiency. In order to decrease the energy cost of mobile nodes, proposed a mobile algorithm that made use of the power of water flow and buoyancy in the mobile path. Performance of the algorithms is evaluated in terms of energy consumption under the considerations of different water flow.
