Research Of Distributed Event Detection Technology In Wireless Sensor Networks

As Event detection is very important in wireless sensor network research. Determinewhether the events occur is very important in wireless sensor networks, many scholars haveconducted a lot of research work in event detection technology. Unreachable for the location,the network application environment is complex and changeable, due to the special nature ofthe scene, the energy of the nodes is limited and error-prone, these features make the existingevent detection technology not easy to perform in practical applications. In this paper, thecharacteristics of the wireless sensor network, event detection technology and thecorresponding hierarchical routing scheme following innovations:Firstly, this paper proposes a sensor network event detection algorithm based on therelational model. For incident detection method based on the spatial correlation of eachneighbor node, the node is given the same correlation properties leading to detection ofinaccurate information; detection process only consider a single attribute factors susceptibleto interference events leading to the detection results, already TTSC improved algorithmbased on a wireless sensor network event detection method (An Event Detection AlgorithmBased On Correlation Model, CDB) based on the relational model, described in detail thedesign of the CDB method and algorithm details, and from the detection accuracy, error rate,loss the sentenced rate and energy consumption of the four aspects of the CDB simulationexperiments with TTSC contrast.Secondly, this paper proposes a hierarchical routing scheme based on zoning. For thetraditional hierarchical routing scheme TEEN algorithms exist based on event-drivenclustering defect uneven energy distribution of the entire network and data transfer processcould easily lead to the irrational distribution of cluster head as well as the optimum numberof cluster head is difficult to determine the network delay problems. To solve these problems,this paper designed a zoning-based hierarchical routing scheme (Advanced ThresholdSensitive Energy Efficient Sensor Network the Routing Protocal, AD-TEEN). Differentclassic TEEN algorithms have been start from the various steps of the routing algorithm, innovative methods to cluster use zoning, has a better performance in the network overallenergy consumption and node survival, it is much more practical.
