Capability analysis and evaluation methods of underwater wireless sensor network

水下无线传感器网络(underwater wireless sensor network,UWSN)综合能力受到传感器能量消耗、探测半径以及网络拓扑等复杂因素影响,为了应对UWSN综合能力评估的挑战性难题,分析了UWSN综合能力与影响参数之间的关系。将UWSN综合能力划分为覆盖能力、连通能力、耐久能力和快速反应能力4个方面,将影响参数划分为约束参数、设备参数和组网参数,提出了覆盖能力、连通能力、耐久能力和快速反应能力的度量模型及UWSN综合能力评估过程模型,实现通过优化调整组网参数,使网络在不同任务和环境下具有优越的整体性能通过仿真平台和仿真试验,结果表明提出模型能较客观计算UWSN的综合能力。

The comprehensive network capacity of an underwater wireless sensor network （UWSN） is affected by complicated factors such as energy consumption, detection radius, and network topology. Thus, networking capa- bility evaluation of UWSN is a challenging issue. To deal with this issue, through an analysis of the relationship be- tween these impact parameters and capability, the capability of UWSN was divided into four items, namely, coverage, connectivity, durability, and rapid reactivity. The parameters that affect the capability items are constraint parameters, device performance, and networking parameters. Measurement models of the abovementioned four capa- bility items were established originally, and the networking capability evaluation process model was presented. Then, an optimal combination of networking parameters can be achieved. The network can achieve advantageous systematic performance under different tasks and environments. Simulation results show that the approach evaluates the capability of UWSN in an objective and efficient manner.
