【摘要】：無(wú)線傳感器網(wǎng)絡(luò)技術(shù)是被國(guó)內(nèi)外相關(guān)領(lǐng)域?qū)＜艺J(rèn)定為當(dāng)今世界非常熱門的前沿技術(shù)。預(yù)計(jì)在未來(lái)的五到十年內(nèi),它將對(duì)人們的日�；顒�(dòng),吃住行帶來(lái)深遠(yuǎn)的影響。隨著信息技術(shù)的爆炸式發(fā)展,讓低功耗、微體積、小成本與多種功能集于一體的傳感器節(jié)點(diǎn)展現(xiàn)在我們的視野之中。也正是這些特征使得傳感網(wǎng)絡(luò)系統(tǒng)的功能作用都非常有局限。然后其能源、通信、計(jì)算等有限性致使整個(gè)系統(tǒng)網(wǎng)絡(luò)安全性能缺失。監(jiān)控區(qū)域中,多個(gè)節(jié)點(diǎn)感知信息時(shí)由于部署位置的密集,會(huì)導(dǎo)致感知的信息值有著很高的冗余,使得網(wǎng)絡(luò)系統(tǒng)能量損耗過大。路由機(jī)制上要求傳感器節(jié)點(diǎn)能夠有效的傳輸可靠的數(shù)據(jù),不能過度的損耗系統(tǒng)能源。因此,系統(tǒng)安全、數(shù)據(jù)信息冗余以及系統(tǒng)功耗便成了本次研究的主要課題。文章從上述幾個(gè)方面對(duì)無(wú)線傳感器網(wǎng)絡(luò)技術(shù)進(jìn)行了探討,主要工作如下：第一,介紹了空間相關(guān)性模型以及其改進(jìn)---無(wú)線傳感器環(huán)狀相關(guān)性模型,將路由協(xié)議進(jìn)行分類,總結(jié)一些典型的路由協(xié)議,為接下來(lái)的研究設(shè)計(jì)方案打下堅(jiān)實(shí)有力的基礎(chǔ)。第二,當(dāng)系統(tǒng)網(wǎng)絡(luò)中的節(jié)點(diǎn)被外部敵方節(jié)點(diǎn)俘獲,發(fā)生系統(tǒng)內(nèi)部攻擊致使網(wǎng)絡(luò)系統(tǒng)安全出現(xiàn)缺失,嚴(yán)重時(shí)系統(tǒng)將癱瘓。針對(duì)此情況,文章在傳感器環(huán)狀空間相關(guān)性模型的基礎(chǔ)之上,傳感器節(jié)點(diǎn)兩兩之間首先進(jìn)行計(jì)算,相鄰節(jié)點(diǎn)再對(duì)節(jié)點(diǎn)進(jìn)行信任評(píng)估,通過計(jì)算,得到相對(duì)較高的信任值,去除低信任節(jié)點(diǎn)的數(shù)據(jù)信息,間接去除惡意節(jié)點(diǎn)的虛假信息,讓信息更為準(zhǔn)確,有效防御系統(tǒng),提高網(wǎng)絡(luò)系統(tǒng)的安全性。第三,為了更好的消除網(wǎng)絡(luò)信息冗余,提高系統(tǒng)節(jié)點(diǎn)生存時(shí)長(zhǎng),文章提出一種基于環(huán)狀空間相關(guān)性的AC-SPIN路由協(xié)議。通過WSN環(huán)狀空間相關(guān)性模型,選擇代表性節(jié)點(diǎn)進(jìn)行數(shù)據(jù)多跳傳輸,進(jìn)而減少網(wǎng)絡(luò)信息冗余。該協(xié)議引入計(jì)數(shù)機(jī)制,當(dāng)節(jié)點(diǎn)計(jì)數(shù)達(dá)到閥值后,緩存數(shù)據(jù)信息并停止轉(zhuǎn)發(fā),收到sink節(jié)點(diǎn)的消息后,再繼續(xù)轉(zhuǎn)發(fā)。這樣的傳輸過程有效消除信息冗余,節(jié)約傳感器節(jié)點(diǎn)的能量消耗,延長(zhǎng)整個(gè)網(wǎng)絡(luò)系統(tǒng)生存時(shí)間。
[Abstract]:Wireless sensor network (WSN) technology is recognized by domestic and foreign experts as the most popular technology in the world. In the next five to ten years, it is expected to have a profound impact on people's daily activities, food, shelter and transportation. With the explosive development of information technology, sensor nodes with low power consumption, micro volume, small cost and multiple functions are displayed in our field of vision. It is these characteristics that make the function of sensor network system very limited. Then the limitation of energy, communication and computation makes the security performance of the whole system network missing. In the monitoring area, when multiple nodes perceive information, because of the dense deployment location, it will lead to high redundancy of perceived information value, which makes the network system energy consumption too large. The routing mechanism requires sensor nodes to transmit reliable data effectively and not to consume system energy excessively. Therefore, system security, data redundancy and system power consumption have become the main topic of this study. This paper discusses the wireless sensor network technology from the above aspects. The main work is as follows: firstly, the spatial correlation model and the improved wireless sensor ring correlation model are introduced, and the routing protocols are classified. Summarize some typical routing protocols and lay a solid foundation for the following research and design. Second, when the nodes in the system network are captured by the external enemy nodes, the system will be paralyzed when the security of the network system is missing due to the attack within the system. In order to solve this problem, based on the sensor ring spatial correlation model, the sensor nodes are first calculated, and the adjacent nodes are evaluated for trust. Through the calculation, a relatively high trust value is obtained. Removing the data information of the low trust node and removing the false information of the malicious node indirectly, making the information more accurate, effectively defending the system and improving the security of the network system. Thirdly, in order to eliminate network information redundancy and improve the lifetime of system nodes, this paper proposes a AC-SPIN routing protocol based on ring spatial correlation. Through the WSN ring spatial correlation model, the representative nodes are selected for multi-hop data transmission, thus reducing the network information redundancy. The protocol introduces the counting mechanism. When the node count reaches the threshold, it caches the data information and stops forwarding. After receiving the message from the sink node, it continues to forward. Such a transmission process effectively eliminates information redundancy, saves energy consumption of sensor nodes, and prolongs the lifetime of the entire network system.
