Study on trust management mechanism of cluster routing in wireless sensor networks based on Beta distribution

With the wide application of wireless sensor network, the realization of WSN energy efficiency and the protection of network security are facing great challenges. The trust management mechanism provides an effective scheme for the WSN security. By evaluating the behavior of nodes, the trust management mechanism of the whole network is established, and the corresponding restrictive measures are adopted to ensure the security of malicious nodes. In this paper, the expected value of Beta probability density distribution function is used as the trust value to optimize the network clustering routing protocol, which can ensure the efficient use of network energy and effectively improve the security of the whole network.
