提高无线传感器网络的可扩展性和鲁棒性是一项重要的任务，自组织的研究已经在这方面进行了大量的研究。然而，在基于纯自组织的更大的网络中，期望行为尚未得到保证。在本文中，我们提出了一种基于控制电位的路由协议，实现了一种新的受控自组织方案，该方案也允许外部控制。该方案通过控制网络中部分节点的外部控制来获得接近最优的网络行为。通过多汇传感器网络的仿真实验，我们证明了全球交通流是可以控制的。例如，流量负载可以在异构分布的汇聚节点之间均衡，基于剩余能量的中继节点之间的负载均衡可以使网络生命周期延长约4倍。该方法对消息丢失具有鲁棒性，对汇聚节点故障具有弹性。
Improving the scalability and robustness of wireless sensor networks is an important task, and much research on self-organization has been conducted toward this end. However, desired behavior is not yet guaranteed in much larger networks based on pure self-organization. In this article, we propose a controlled potential-based routing protocol implementing a novel controlled self-organization scheme that also allows for external control. The scheme obtains close-to-optimal network behavior by this external control which controls a part of nodes in the network. We show that global traffic flow can be controlled through simulation experiments with a multi-sink sensor network. For example, traffic loads can be equalized among heterogeneously distributed sink nodes, and load balancing among the relay nodes based on remaining energy can bring an approximate four times extension of network lifetime. The proposed method is furthermore robust to message loss and resilient to failure of the sink node.
