The Research Of Safe And Low Energy Consumption Clustering Routing Protocol In WSN

While the sensor networks which has broad application prospects in many areas to get a wide range of applications, wireless sensor network security, reliability, and energy research is an insurmountable stage. The routing protocols of clustering structure based on energy and security considerations are hot issues in wireless sensor networks research, However, taking into account the two routing protocols for wireless sensor networks is relatively small.This article proposes a clustering routing protocol that gives considerations to security and low energy consumption .The proposed routing protocol based on the research of the trust model of wireless sensor networks and the energy consumption of nodes, it also aims at the vulnerable problem of energy limited wireless sensor networks. The election of cluster head in the clustering routing protocol has considered the trust of nodes, the residual energy of node and the geographical position of node. The trust mechanism in cluster head selection can prevent the malicious acts of the malicious nodes. The consideration of residual energy in algorithms solves the problem of early death of cluster head because of excessive energy consumption. For the problem of uneven distribution of cluster head node, the algorithm introduces zone division mechanism to reduce the excess energy consumption between cluster head and members of the clusters caused by the transmission distance.The simulation experiments show that the algorithm can identify the malicious nodes with malicious behavior, so it has good energy efficiency, and also improves the network security, prolongs the network life cycle and enhances the robustness and practicality of the network, in which the change of the area size and the number of nodes in simulation experiments show that the algorithm is more suitable for large area and large density network environment.
