Research On Routing Attack Detection In Wireless Sensor Network

Internet of things is developing rapidly in recent years,it is called the third wave of world information industry development.Wireless sensor network is one of the core technology of Internet of things.As the increasingly development of sensor technology,distributed information processing technology and microelectronics technology,WSN has formed a huge industry with influence widely.With the maturity of various aspects technology,the application fields of wireless sensor network is gradually from the original military expansion to civilian use.This situation made the development of wireless sensor networks being in a more complicated environment,its security problem become more severe.As people keep trying and reform with wireless sensor networks,the security problem exposed itself gradually,and it often brought huge losses,in order to ensure its follow-up development,We have to spend a lot of manpower and material resources to ensure the safety of the wireless sensor network so that it can meet safety standards,it is the necessary condition for its development.Security problems of wireless sensor network is the main focus of this article,especially the security problems of network layer.Security problems exposed in network layer of Wireless sensor network is particularly serious,various reasons and widely influence,usually difficult to predict and prevent.First,we introduced the basic concept of Internet of things and wireless sensor network,especially their characteristics,the development status,application fields,network structure;Then we introduce the different kinds of network layer routing protocol,and its characteristic,and carries on the comparison;After that we investigate the famous network attack detection model,they are encryption model,flow model and trust model.Network layer attack detection of WSN is the key point of this article,First,we studied and analyzed the principle and characteristics of the attack ways in network layer of WSN,and then we carried on the experiments of flood attacks,black hole attack and routing destroy attack in the concrete implementation environment.Then proposed a kind of attack detection method based on two-dimensional credibility.The original attack detection of trust model only concerned about the efficiency of detection,ignore the real-time detection.The proposed method can ensure the efficiency and real-time detection at the same time.Finally,we designed a client for our attack detection experiments,using the sensor nodes(MicaZ)to make up experiment environment which running AODV routing protocol.Finally we elaborated the framework and function of each part of the system minutely.
