Wireless location-aware networking

手持无线通信设备现在在加拿大社会几乎无处不在。无线设备的用户要求应用程序允许他们在移动时充分利用通信能力。该项目的目标是将位置感知集成到无线局域网和无线城域网中，例如基于IEEE 802.11和802.16的网络，以便这些网络的用户和运营商可以充分利用这些网络提供的移动性和连续连接。这种集成包括寻找新的位置估计技术以及开发使用位置信息的应用程序。该项目的第一阶段将侧重于开发能够准确定位移动终端的位置估计技术，而无需在无线网络基站或用户终端中添加额外的硬件。机器学习和顺序估计技术将用于从无线网络中已有的测量数据中获得准确的位置信息。当位置估计系统被开发出来后，使用位置信息的应用程序和网络控制系统将被创建。探索在位置估计系统、用户应用程序和网络控制系统之间交换信息的最佳方法。该项目将开发将位置感知计算原理集成到标准无线网络的方法，作为无线局域网，大多数加拿大人现在每天都在使用。这将扩展这些网络的功能，而不仅仅是取代有线网络。然后，利用移动访问这些网络的应用程序将被启用。

Handheld wireless communications devices are now nearly ubiquitous in Canadian society. Users of wireless devices are demanding applications that allow them to take full advantage of the ability to communicate while they are mobile. The objective of this project is to integrate location awareness into wireless local area and wireless metropolitan area networks, such as IEEE 802.11 and 802.16 based networks, so the users and operators of these networks may take full advantage of the mobility and continuous connectivity offered by these networks.  This integration consists of finding new location estimation technologies as well as the development of applications that use location information.The first stage of the project will focus on the development of location estimation techniques that can accurately locate mobile terminals without requiring additional hardware in the wireless network base stations or user terminals.  Machine learning and sequential estimation techniques will be used to obtain accurate location information from measurements already available within the wireless networks. When location estimation systems have been developed, applications and network control systems that use the location information will be created. Explorations to find the best methods of exchanging information between the location-estimation systems, user applications, and network control systems will be performed.  This project will develop methods for the integration of the principles of location-aware computing into the standard wireless networks, as wireless local area networks, that the majority of Canadian now access every day.  This will expand the capabilities of these networks beyond just the replacement of wired networks.  Applications that take advantage of the mobile access these networks will then be enabled.
