我们通过提出智能利用水下传感器节点的能量收集能力来证明持久水下网络的可行性。我们定义了一个数据路由框架，允许发送者在考虑剩余能量和可预见的可收获能量的情况下选择最佳转发中继。我们的转发方法名为 HyDRO，用于收集感知数据路由，还配置为考虑信道条件和路由范围内的剩余能量，通过本地信息共享执行网络范围内的优化。我们的协议的性能是通过模拟场景进行评估的，该场景建模包括真实的水下设置以及基于记录痕迹的能量收集。 HyDRO 与最先进的水下网络转发协议进行比较。我们的结果表明，联合考虑剩余和预测的能源可用性是实现更低的能源消耗和延迟，同时获得更高的数据包传输率的关键。
We demonstrate the feasibility of long lasting underwater networking by proposing the smart exploitation of the energy harvesting capabilities of underwater sensor nodes. We define a data routing framework that allows senders to select the best forwarding relay taking into account both residual energy and foreseeable harvestable energy. Our forwarding method, named HyDRO, for Harvesting-aware Data ROuting, is also configured to consider channel conditions and route-wide residual energy, performing network wide optimization via local information sharing. The performance of our protocol is evaluated via simulations in scenarios modeled to include realistic underwater settings as well as energy harvesting based on recorded traces. HyDRO is compared to state-of-the-art forwarding protocols for underwater networks. Our results show that jointly considering residual and predicted energy availability is key to achieve lower energy consumption and latency, while obtaining much higher packet delivery ratio.
