无线传感器网络（WSNs）越来越多地应用于低能耗和低成本是首要考虑因素的应用中。随着使用的增加，需要从一开始就解决其可靠性、可用性和可服务性问题。传统的增加冗余节点和在控制协议中加入可靠性的方案只能有效地提高整个无线传感器网络的可靠性。WSN节点的可用性和可维护性可以通过为各个传感器节点提供远程测试和修复基础设施来解决，这些基础设施与现有的板载测试基础设施（包括标准JTAG链）非常匹配。我们提出并评估可扩展的WSN节点架构，以提高可用性，以及使用COTS组件实现所提出的解决方案。
Wireless sensor networks (WSNs) are being increasingly used in applications where low energy consumption and low cost are the overriding considerations. With increased use, their reliability, availability and serviceability need to be addressed from the outset. Conventional schemes of adding redundant nodes and incorporating reliability in control protocols can effectively improve only the reliability of the overall WSN. The availability and serviceability of WSN nodes can be addressed by providing the remote testing and repair infrastructure for the individual sensor nodes that is well matched with existing on-board test infrastructure, including standard JTAG chains. We propose and evaluate scalable architectures of WSN nodes for increased availability as well as implement the proposed solutions using COTS components.
