    • In the public WLAN systems, reliable user re-authentication for mobility support is an essential step. However, re-authentication during handoff procedures causes long handoff latency which deteriorates the quality of service specifically for real-time multimedia applications. One possible solution is to authenticate the Mobile Node (MN) in advance with all the neighboring Access Points (APs) and distribute the Session Keys to them. However, the key issue is how to optimally and efficiently select the neighboring APs. In the preferred embodiments, we propose a system that takes into account the user current "Geo-Location". "Mobility Pattern" and "Application Running on MN": estimates the "Expected Mobility Zone" (EMZ) and selects an appropriate set of candidate APs corresponding to the MN's geo-location. The EMZ may comprise of APs belonging to Intra-domain". "Inter-domain" or "Inter-technology Networks" (e.g., WLAN, WiMAX1 and Cellular etc). The system assumes that not only the Mobile Nodes but also the Fixed Nodes (APs or Base Stations) are capable of knowing their Geo- Location Coordinates X, Y, Z. This capability may come either by integrating GPS receiver or through any other alternate, state of the art or future positioning technologies in the APs.
    • 在公共WLAN系统中,可靠的用户重新认证用于移动性支持是必不可少的一步。 然而,在切换过程中的重新认证导致长的切换等待时间,这恶化了专门用于实时多媒体应用的服务质量。 一个可能的解决方案是提前与所有相邻接入点(AP)认证移动节点(MN),并将会话密钥分发给他们。 然而,关键问题是如何优化和有效地选择相邻的AP。 在优选实施例中,我们提出考虑用户当前的“地理位置”的系统。 “移动模式”和“在MN上运行的应用程序”:估计“预期移动区域”(EMZ),并选择与MN的地理位置对应的适当的候选AP集合。 EMZ可以包括属于域内的AP“域间”或“技术间网络”(例如,WLAN,WiMAX1和蜂窝等),系统假定不仅移动节点而且固定节点 (AP或基站)能够知道它们的地理位置坐标X,Y,Z.该能力可以通过将GPS接收机或通过任何其他备选的,现有技术或未来定位技术集成在AP中来实现。

    • A system for key management in sensor networks which takes the location of sensor nodes into consideration while deciding the keys to be deployed on each node. This system reduces the number of keys that have to be stored on each sensor node and also provides for the containment of node compromise. Thus compromise of a node in a location affects the communications only around that location. The location dependent key management system does not require any knowledge about the deployment of sensor nodes. The system starts off with the loading of a single key on each sensor node prior to deployment. Subsequent to deployment a plurality of beacons is transmitted a plurality of different transmission ranges from each anchor node, said beacons containing at least one nonce. Each sensor node receives beacons depending upon its location in the network. Thus, sensor nodes in different locations have different nonce sets, and each sensor node derives updated keys using a combination of the common key and its set of nonces. The system allows for additions of sensor nodes to the network at any point in time.
    • 传感器网络中的密钥管理系统,在决定要部署在每个节点上的密钥时,考虑传感器节点的位置。 该系统减少了必须存储在每个传感器节点上的密钥数量,并且还提供了对节点折衷的控制。 因此,位置中的节点的妥协影响仅在该位置周围的通信。 位置依赖密钥管理系统不需要关于传感器节点部署的任何知识。 在部署之前,系统首先在每个传感器节点上加载单个密钥。 在部署之后,从每个锚节点传送多个不同传输范围的多个信标,所述信标包含至少一个随机数。 每个传感器节点根据其在网络中的位置接收信标。 因此,不同位置的传感器节点具有不同的随机数集合,并且每个传感器节点使用公共密钥及其集合的随机数的组合来导出更新的密钥。 该系统允许在任何时间点向网络添加传感器节点。
