摘要: 随着无线感测网路技术的进步,未来生活环境中,将布满感测器,利用无
线网路互相连结,并且负责监测并搜集和生活环境相关的资料,此一环境架构为
无线感测网路环境。因此,利用无线感测网路于农业之应用,如农场的环境监控、
植物生长测量等,将是无线感测网路极为重要应用。然无线感测网路具有低耗电、
不具庞大记忆单元、低无线网路通讯频宽及硬体运算能力较弱等限制。因无线感
测器之限制,使得在无线感测网路上的资料处理、查询与传统分散式系统有所不
同,且这些限制使得如何在有限的资源内,提供低耗电,有效率之资料处理与查
询成为日渐重要的课题。
本计画为一为期三年之总计画‘适用于农业之无线行动感测网路技术之研
究’之一子计画。在此子计画中,我们将研发于无线感测网路系统中,确保资料
正确,节省电源之无线感测网路资料处理机制。在本子计画中,主要的研究课题
包含:(1)提供确保感测资料精确性机制;(2)有效率省电资料查询处理;(3)资料收
集与探勘架构。首先,有鉴于感测器可能会有损坏,导致资料的不正确,我们将
研发过滤错误资料机制,以确保感测资料的正确性。其次,我们将研究多个资料
查询最佳化及近似资料查询机制,以降低感测器的电源耗损。最后,我们将建构
一阶层式资料收集与探勘架构,以便有效率的收集资料并资料探勘,将有助于瞭
解感测资料所隐含之意义。
近年来,无论工业界或是学术界对于无线感测网路均相当的重视并且投入
大量的人力及研究,无线感测网路于农业应用极为适合,我们相信此计画之执行,
将可研发出适用于无线感测网路系统中,资料处理前瞻性技术,并实作于农场环
境以作为学理与实务验证。
The rapid progress of wireless communication and embedded micro-sensing MEMS
technologies has made wireless sensor networks possible. It is expected that wireless
sensors will be widely deployed for measurement, detection and surveillance applications.
Due to the very nature of wireless sensor networks, applying wireless sensor networks for
agricultural fields is deemed an important application. Note that sensors have several
resource constraints such as power consumption, limited computing capability, smaller
storage space and low bandwidth in communications. These resource constraints on
sensors call for the design of data management in wireless sensor networks.
This project is under the integrated project ‘Wireless Mobile Sensor Network
Technologies for Agricultural Applications ’, and aims at designing reliable data
management and mining mechanisms in wireless sensor netowrks. Our primary goals
include (1) developing data accuracy guaranteed mechanism, (2) devising energy efficient
data query processing methods, and (3) exploring the feature of heterogeneous sensor
nodes for data collection and in-network mining. More specifically, we will first develop
trust relations among sensor nodes and explore trust relations for filtering faulty sensor
nodes so as to ensure the correctness of data. Next, by exploiting the similarities in both
data queries and sensing data, we will develop two novel query processing mechanisms
for power saving. Finally, in order to discover the knowledge of sensing data, we shall
develop a hierarchical data collection and mining architecture. In light of the hierarchical
architecture, we will develop in-network mining algorithms.
Through the collaboration with other sub-projects, a prototype of wireless sensor
networks for agricultural applications will be built. In view of the increasing attention on
wireless sensor networks, we strongly believe this project is very timely and will deliver
results of both theoretical and practical importance.
