将异构的移动的设备，如移动的电话引入到大规模稀疏无线传感器网络中是一个很有前途的研究方向。这些充当移动的接收器的设备为网络提供了许多好处。例如，它们有助于提高可扩展性，保持负载平衡，节省能源，延长网络寿命和商业实施。研究了移动的汇聚节点的不同特性和行为对混合无线传感器网络的影响。分析和仿真结果表明，与尽可能多地部署移动的sink节点相比，选择合适的sink节点数量、传输范围、速率和汇聚方式，可以显著降低端到端的平均数据传输时延，提高系统的能量节约。在稀疏网络中对固定sink和移动的sink的性能指标进行了比较沿着得出了移动的sink可以带来更高的数据成功率和能量平衡的结论。
Introducing heterogeneous mobile devices, such as mobile phones into the large scale sparse wireless sensor networks is a promising research direction. These devices acting as mobile sinks offer many benefits to the network. For instance, they help to improve scalability, maintain load balance, conserve energy, prolong network lifetime and implement commercially. The paper investigates the impacts of different features and behavior of mobile sinks on the hybrid wireless sensor networks. Analysis and simulation results show that, instead of deploying mobile sinks as much as possible, choosing appropriate number, transmission range, velocity and gathering mode of the sink nodes can significantly decrease the average end-to-end data delivery delay and improve the energy conservation. The comparisons of performance metrics between fixed sinks and mobile sinks are also made in sparse networks along with the results that mobile sinks can bring higher data success rate and energy balance.
