Research On Clustering Data Fusion Algorithm Based On Relay Node Mechanism

Now has entered the era of high technology,all aspects of life have gradually become intelligent.There are a large number of applications emerging for Wireless Sensor Networks.For example,the rising of the wisdom of the city,wisdom of traffic,wisdom of community,which belong to the Internet of Things,but the real realization can not be separated from the development of the sensor.In order to achieve the goals,the target area must deploy a certain number of sensor nodes to form a sensor network,the way to collect the data that researchers are interested.From the day that wireless sensor network was born,more and more researchers to join to this research team.The difficulty that we can reduce energy consumption but under the condition how to extend the life cycle.If we can not solve this difficult,with the laying of wireless sensor networks growing,which will restrict the development of wireless sensor networks seriously.In order to better realize the data collection and transmission work,the relevant researchers introduce clustering routing technology and collaborative communication technology and assimilate two technologies into the wireless sensor network improving the performance of wireless sensor networks to a certain extent.The cluster node is consist of cluster head node and cluster member node.The cluster node is responsible for collecting data and transmitting the data to the cluster head node.The cluster head node is responsible for receiving data and data fusion and transmitting the fusion data to the base station.The use of clustered routing protocols is the most powerful way to reduce energy consumption and balance load in wireless sensor network both in theory and practice.In the traditional LEACH clustering protocol,it changes the selection mechanism of the cluster head,which avoids the problem of network paralysis caused by the energy consumption of the cluster head node.However,the cluster head node is not distributed evenly and the redundant data is collected.Based on the above shortcomings,this paper proposes a clustering data fusion algorithm based on the relay node mechanism,and uses the clustering routing protocol to add the relay node mechanism,and this paper optimizes the selection of cluster head nodes.The relay node is responsible for communicating with the base station.This can reduce the energy consumption of the cluster head node effectively,thus balancing the network load and prolonging the survivability of the wireless sensor network.
