Research And Implementation Of WSN Routing Algorithm Based On Security Mechanism

Wireless sensor network is a leading research direction in the field of computer network and communication area." Without any infrastructure,it is possible to perform real-time monitoring,sensing and obtaining data from a wide range of wireless sensors,enabling them to conduct real-time monitoring,sensing and obtaining information via wireless networks,and transmit and transfer information via wireless networks." Wireless sensor network is facing a serious challenge,and it is urgent to solve the problem of wireless sensor network in terms of security and energy.In view of the current premise that the current wireless sensor network routing protocol is mainly energy-saving,the security considerations are less.This paper studies the working principle,routing protocol and attack mode of wireless sensor networks.By analyzing the typical clustering routing protocol LEACH protocol,an improved algorithm is proposed for its security,energy consumption and uneven clustering.The main research work is as follows:Aiming at the problems of uneven clustering and unbalanced energy consumption in LEACH protocol,a LEACH-SPW protocol based on spider network segmentation technology is proposed.This protocol can divide the coverage of the network to make regular regional division within the network.The closer the base station is to the cluster and the number of nodes,the more energy,The less the other way around.In this way,multiple clusters and nodes closer to the base station can be divided into data communication tasks,and a small number of clusters and nodes farther away from the base station share less data communication tasks,avoid High power consumption due to the distance from the base station,achieving the purpose of reducing node energy consumption and prolonging the network lifetime;considering the energy consumption problem of data transmission between clusters,the energy generated by direct or indirect data transmission between the cluster head and the base station is determined.The power consumption is compared to select single-hop or multi-hop data transmission to save energy consumption;for the cluster head node selection method,the node with large residual energy is elected as the cluster head node with higher probability.This will increase the survival time of the network.In addition,the security mechanism for wireless sensor network routing protocol is introduced,The safety mechanism of the LEACH-SPW is added to the security mechanism,dividing the web area and updating keys so as to enhance the security and security of the network,and the LEACH-SPW protocol results in a safer and more stable operation.Finally,the LEACH-SPW protocol based on security,the LEACH-SPW protocol is presented.Compared with the LEACH protocol,the LEACH-SPW protocol is superior to the LEACH protocol,and the results of the LEACH-SPW are better than LEACH,which proves the feasibility and effectiveness of the proposed protocol.
