移动的sink可以用来平衡无线传感器网络中传感器节点的能量消耗。移动的汇被要求通知传感器节点关于他们的新的位置信息，只要有必要。然而，频繁的位置更新从移动的汇可以导致传感器节点的快速能量消耗和无线传输中的冲突增加。我们提出了一种新的解决方案，自适应位置更新的移动的汇来解决这个问题。当信宿移动时，它只需要在局部区域内而不是在整个网络中广播其位置信息。理论分析和仿真研究均表明，该方案在降低节点能耗的同时，减少了无线传输中的冲突，可应用于大规模的无线传感器网络。
Mobile sinks can be used to balance energy consumption for sensor nodes in Wireless Sensor Networks (WSNs). Mobile sinks are required to inform sensor nodes about their new location information whenever necessary. However, frequent location updates from mobile sinks can lead to both rapid energy consumption of sensor nodes and increased collisions in wireless transmissions. We propose a new solution with adaptive location updates for mobile sinks to resolve this problem. When a sink moves, it only needs to broadcast its location information within a local area other than among the entire network. Both theoretical analysis and simulation studies show that this solution consumes less energy in each sensor node and also decreases collisions in wireless transmissions, which can be used in large-scale WSNs.
