通过全面感知、可靠传输、智能化处理来实现人与人、物与物、人与物之间相连的物联网,是继计算机与互联网的应用与普及之后,信息世界掀起的第三次技术革命浪潮。在中国,物联网已经被纳入到国家“十二五”专项规划,毫无疑问,随着技术的成熟与体系的完善,它将彻底改变我们的生活。而无线传感器网络作为物联网时代最具有标志性的感知与传输技术之一,将会是今后网络研究与应用的热点。然而,传统无线传感器网络的研究重点往往在路由算法、密钥分配、体系结构等方面,节点信任问题却很容易受到忽视。已有的一些信任管理模型中,并没有充分考虑节点之间信任的时效问题,且信誉值计算方式以及权重存在着不合理性。因此,文章在前人研究的基础上,根据无线传感器网络性质,设置合理可行的博弈机制,提出了一种基于重复博弈的信任模型,并通过设立惩罚激励机制,依据节点策略的选择,对其信誉值进行更新以解决时效问题;通过仿真实验,证明该信任管理模型能够有效地对无线传感器网络节点进行信任的评价,抑制自私节点、打击恶意节点,可明显提高网络的可靠性。
通過全麵感知、可靠傳輸、智能化處理來實現人與人、物與物、人與物之間相連的物聯網,是繼計算機與互聯網的應用與普及之後,信息世界掀起的第三次技術革命浪潮。在中國,物聯網已經被納入到國傢“十二五”專項規劃,毫無疑問,隨著技術的成熟與體繫的完善,它將徹底改變我們的生活。而無線傳感器網絡作為物聯網時代最具有標誌性的感知與傳輸技術之一,將會是今後網絡研究與應用的熱點。然而,傳統無線傳感器網絡的研究重點往往在路由算法、密鑰分配、體繫結構等方麵,節點信任問題卻很容易受到忽視。已有的一些信任管理模型中,併沒有充分攷慮節點之間信任的時效問題,且信譽值計算方式以及權重存在著不閤理性。因此,文章在前人研究的基礎上,根據無線傳感器網絡性質,設置閤理可行的博弈機製,提齣瞭一種基于重複博弈的信任模型,併通過設立懲罰激勵機製,依據節點策略的選擇,對其信譽值進行更新以解決時效問題;通過倣真實驗,證明該信任管理模型能夠有效地對無線傳感器網絡節點進行信任的評價,抑製自私節點、打擊噁意節點,可明顯提高網絡的可靠性。

The IOT which is to achieve the connection between human and things through the complete perception, reliable transmission and intelligent processing is the third wave of technology revolution in information industry after the application and popularization of computer and Internet. In China, IOT is taken into account as the twelfth ifve-year plan. Undoubtedly, with the Maturity of technology and system, it will completely change our lives. As one of the most iconic technology in the Internet of things era, the wireless sensor networks (WSNs) will be the focus and focal point of the present and future application and research. However, the focuses of WSNs are the routing algorithm, key distribution and architecture in previous studies. And the trust of node has been always overlooked. In some existing trust management models, they didn't quite take the time effect issue among nodes into consideration, and there were irrationality in weights and the way of computing reputation value. According to WSNs’ characteristics, a reasonable and feasible model which is based on repeated games is created in this paper .Besides ,we establish a punishment and reward mechanism to solve the time issue of node’ reputation. Finally, we conifrmed the trust manage model could evaluation node’ reputation effectively in WSNs. Through inhibition selifsh node and malicious node, the reliability of WSNs has got a great progress.
