本文重点研究了一种在低功率无线个人网(6LoWPAN)传感器节点上支持IPv6移动性的方案。我们定义了一种基于代理移动IPv6的6LoWPAN移动传感器节点协议6LoMSN(PMIPv6)。传统的PMIPv6标准仅支持单跳网络，不能应用于基于多跳的6LoWPAN。它不支持6LoMSN的移动性，6LoWPAN网关名为6LoGW，无法检测6LoMSN的PAN附着。因此，我们定义了6LoMSN的移动通知，以支持其在基于多跳的6LoWPAN环境中的移动性。6LoMSN的附加通过使用路由器请求(RS)和路由器通告(RA)消息来降低无线链路上的信令成本。性能结果表明，我们提出的方案可以最小化总的信令开销和切换时延。此外，我们还介绍了基于PMIPv6的6LoMSN移动性在医疗系统中的设计与实现。根据实验结果，所提出的基于PMIPv6的6LoMSN的6LoWPAN可以预期使用更多的电池寿命。我们还验证了6LoMSN可以保持连接，即使它可以在没有移动协议栈的情况下在PAN之间自由移动。
In this paper, we focus on a scheme that supports mobility for IPv6 over Low power Wireless Personal Area Network (6LoWPAN) sensor nodes. We define a protocol for 6LoWPAN mobile sensor node, named 6LoMSN, based on Proxy Mobile IPv6 (PMIPv6). The conventional PMIPv6 standard supports only single-hop networks and cannot be applied to multihop-based 6LoWPAN. It does not support the mobility of 6LoMSNs and 6LoWPAN gateways, named 6LoGW, cannot detect the PAN attachment of the 6LoMSN. Therefore, we define the movement notification of a 6LoMSN in order to support its mobility in multihop-based 6LoWPAN environments. The attachment of 6LoMSNs reduces signaling costs over the wireless link by using router solicitation (RS) and router advertisement (RA) messages. Performance results show that our proposed scheme can minimize the total signaling costs and handoff latency. Additionally, we present the design and implementation of the 6LoMSN mobility based on PMIPv6 for a healthcare system. According to the experimental results, the 6LoMSN of the proposed PMIPv6-based 6LoWPAN can be expected to use more of the battery lifetime. We also verify that the 6LoMSN can maintain connectivity, even though it has the freedom of being able to move between PANs without a mobility protocol stack.
