The Research On Security And Routing Of Sensor Network Correlation Model

Wireless sensor network (WSN) technology is being recognized as very popular by experts of related fields at home and abroad in today’s world of cutting-edge technology.Expected in the next five to ten years, it will bring far-reaching on people’s daily activities, such as food、house and action.The explosive development of information technology makes the low power consumption、micro-volume、low cost and a variety of functions sensor nodes present in our research.It is these characteristics that make the performance of sensor networks are very limited.Then its energy, communications and computing limited the absence of the whole system network security performance. In monitoring area, due to the multiple nodes densely deployed position, many sensor nodes Sensory information will lead to a high perceived value redundant and make the huge energy loss in the network system.Routing mechanism required in the sensor nodes can effective reliable transmission of data, nor excessive node energy dissipation.Therefore, system security, data redundancy and system power consumption has become the main subject of this study.The article from the several aspects of wireless sensor networks are discussed,The main work:First, this paper introduces the spatial correlation model and its improved model---cyclic correlation model of the wireless network sensors.It will classify routing protocols and summarize some typical routing protocols, and lay a strong foundation for the next design solution.Second, when the system nodes are captured by external enemy node in the network,It happens within the system against the network system security appear loss, the more serious may result the system be paralyzed.Aiming at this situation, based on the sensor network cyclic spatial correlation model.we can calculate the trust value between two sensor nodes in the first.in addition,Adjacent nodes then can calculate the node’s trust evaluation to the relatively high value of the trust,It can remove the low trust data information of nodes and remove false information of malicious nodes by indirectly.so that,It makes the information more accurate, the defense system more effectively and improve the security of network system.Third, in order to allow the system to better eliminate redundant information and prolong the system sensors survive more long.This paper presents an annular space correlation based multipath routing protocol(AC-SPIN).Through the WSN annular space correlation model, It can selecting the representative node multi-hop transmission data to reduce the network information redundancy. The agreement introduced counting mechanism, when the node count reaches the threshold, sensor nodes cached data and stop forwarding.After receiving the message of sink node,then continue forward. Such a transfer process eliminates redundant information effectively and save consumption of the system sensors energy and prolong the survival time of the entire network system.
