Wireless sensor network testbed

无线传感器网络（WSN）是一个热门的研究课题，使用无线传感器节点的应用越来越多。因此，继续改进这项新兴技术是非常重要的。该方案的主要目标是获得一个由多个微型无线传感节点、基站和处理中心组成的无线传感器网络试验台。所有节点通过无线电频率相互通信。该测试平台将使我们能够解决以下三个主要研究目标：1)引入新的规划算法，以设计无线传感器网络。2)提出新的网络协议来解决诸如信息如何通过网络发送（路由）以及如何在空间和时间上关联特定事件（本地化和时钟同步）等问题。3)通过开发处理网络内部信息的新模型（数据聚合/融合）来提高网络的性能。到目前为止，评估我们的算法效率的唯一手段是分析分析和模拟。然而，模拟实验与现实生活实验之间存在着巨大的差距。无线传感器网络试验台是帮助我们开发和测试新算法的必要工具。

Wireless sensor network (WSN) is a hot research topic and the number of applications using wireless sensor nodes is increasing very rapidly. It is therefore very important to continue to improve this emerging technology.The main goal of this proposal is to acquire a wireless sensor network testbed, which is composed of several tiny wireless sensing nodes, base stations and processing centers. All the nodes communicate among each other via radio frequencies.This testbed will allow us to tackle the following three main research objectives:1) Introduce new planning algorithms in order to design wireless sensor networks.2) Propose new network protocols to solve problems such as how the information is sent through the network (routing) and how to correlate particular events in space and time (localisation and clock synchronisation).3) Improve the performance of the network by developing new models for processing the information inside the network (data aggregation/fusion).Until now, the only means for evaluating the efficiency of our algorithms have been analytical analysis and simulation. However, there is a huge gap between simulation and real life experiments. The wireless sensor network testbed is a necessary tool that will help us to develop and test new algorithms.
