Various surveys show that Canadian consumers and businesses have a strong interest in adopting new wireless products to improve their standard of living and increase their productivity. The evolution of wireless access towards data-oriented connections, has led to the coexistence of multiple-access technologies providing new products and services, and exhibiting improved system characteristics (lower power consumption and higher data rates). Over the last seven years, novel architectures like ad hoc and wireless sensor networks have generated new challenges regarding the way radio communication infrastructures must be addressed. Unlike traditional approaches, these architectures require complete self-organization of their nodes as well as support for mobility. The main objective of the proposed research project is to develop efficient and cooperative ad hoc and wireless sensor networks (WSN) based on ultra-wideband (UWB) radio technology to meet the requirements of this new market. The first goal of the research program is to apply UWB with innovative front-end solutions to enhance the system performances in different applications. The second goal is to deploy cooperative algorithms applied to WSN in order to find high efficiency solutions with low complexity implementations for these applications. To achieve these research objectives, the project will be divided into two different directions, which will be investigated in parallel. First, ad hoc UWB wireless sensors will be designed for cooperative localization/tracking in two different indoor environments (in-building and mining). Second, UWB radar sensors will be designed for vehicule collision avoidance applications such as mobile robots and outdoor ground vehicles. The originality of this hardware and algorithmic project consists in combining ad hoc network with wireless sensor devices using a low complexity UWB transceiver front-end in conjunction with novel cooperative algorithms to give application flexibilities, low-cost products and high performance results. Consequently, improved system performance and network cost represent the advantages of the proposed approach compared to the existing ones.

各种调查显示，加拿大消费者和企业对采用新的无线产品来提高生活水平和提高生产力有着浓厚的兴趣。无线接入向面向数据的连接的发展导致了多址技术的共存，提供了新的产品和服务，并表现出改进的系统特性（更低的功耗和更高的数据速率）。在过去的七年里，自组织网络和无线传感器网络等新颖的架构对无线电通信基础设施的解决方式产生了新的挑战。与传统方法不同，这些架构需要节点的完全自组织以及对移动性的支持。拟议研究项目的主要目标是开发基于超宽带（UWB）无线电技术的高效、协作的自组织和无线传感器网络（WSN），以满足这一新市场的要求。该研究计划的首要目标是将UWB与创新的前端解决方案一起应用，以提高不同应用中的系统性能。第二个目标是部署应用于 WSN 的协作算法，以便为这些应用找到低复杂度实现的高效解决方案。为了实现这些研究目标，该项目将分为两个不同的方向，并行进行研究。首先，特设 UWB 无线传感器将设计用于在两种不同的室内环境（建筑物内和采矿）中进行协作定位/跟踪。其次，UWB雷达传感器将设计用于车辆防撞应用，例如移动机器人和室外地面车辆。该硬件和算法项目的独创性在于，使用低复杂度的 UWB 收发器前端以及新颖的协作算法，将自组织网络与无线传感器设备相结合，从而提供应用灵活性、低成本产品和高性能结果。因此，与现有方法相比，改进的系统性能和网络成本代表了所提出的方法的优势。
