低功耗无线个域网（LoWPAN）仍处于早期发展阶段，但可想象的使用场景和应用范围是巨大的。该范围通过其包含在具有IPv6低功耗个域网（6LoWPAN）的互联网中而扩展。这表明，多技术拓扑、安全性和移动性支持将在6LoWPAN中普遍存在。基于移动性的通信增加了连接性，并允许扩展和调整LoWPAN以适应其位置和环境基础设施的变化。然而，所需的移动性在很大程度上取决于单个服务场景和LoWPAN架构。在这种情况下，针对军事、消防救援或医疗保健等需要频繁改变位置的关键应用提出了优化的解决方案。我们的场景是炼油厂的健康监测，在这些场景中发现了许多有效使用LoWPAN的障碍，主要是由于传输介质的特性，即高损耗，高延迟和低可靠性。因此，很难在移动性要求如此严格的情况下提供连续的健康监测。在本文中，提出了一个范例的移动性在6LoWPAN的关键环境。一方面，内部移动性由GinMAC支持，GinMAC是IEEE 802.15.4的扩展以支持拓扑控制算法，其透明地提供内部移动性，以及移动的节点（MN）的移动方向确定（MDD）。另一方面，互联移动性是基于访问网络中的网络参数的预先设置，例如转交地址和信道，以达到快速和平滑的切换。由于MDD允许发现MN正朝着其移动的下一个6LoWPAN网络，因此达到了预设置。所提出的方法已经模拟，原型，评估，并正在研究的情况下，可穿戴生理监测在危险的工业领域，特别是炼油厂，在Ginseng欧洲项目的范围。
Low-power Wireless Personal Area Networks (LoWPANs) are still in their early stage of development, but the range of conceivable usage scenarios and applications is tremendous. That range is extended by its inclusion in Internet with IPv6 Low-Power Personal Area Networks (6LoWPANs). This makes it obvious that multi-technology topologies, security and mobility support will be prevalent in 6LoWPAN. Mobility based communication increases the connectivity, and allows extending and adapting LoWPANs to changes in their location and environment infrastructure. However, the required mobility is heavily dependent on the individual service scenario and the LoWPAN architecture. In this context, an optimized solution is proposed for critical applications, such as military, fire rescue or healthcare, where people need to frequently change their position. Our scenario is health monitoring in an oil refinery where many obstacles have been found to the effective use of LoWPANs in these scenarios, mainly due to transmission medium features i.e. high losses, high latency and low reliability. Therefore, it is very difficult to provide continuous health monitoring with such stringent requirements on mobility. In this paper, a paradigm is proposed for mobility over 6LoWPAN for critical environments. On the one hand the intra-mobility is supported by GinMAC, which is an extension of IEEE 802.15.4 to support a topology control algorithm, which offers intra-mobility transparently, and Movement Direction Determination (MDD) of the Mobile Node (MN). On the other hand, the inter-mobility is based on pre-set-up of the network parameters in the visited networks, such as Care of Address and channel, to reach a fast and smooth handoff. Pre-set-up is reached since MDD allows discovering the next 6LoWPAN network towards which MN is moving. The proposed approach has been simulated, prototyped, evaluated, and is being studied in a scenario of wearable physiological monitoring in hazardous industrial areas, specifically oil refineries, in the scope of the GinSeng European project.
