Energy efficient hierarchical trust management scheme for solving cluster head compromising problem in wireless sensor networks

Abstract

Wireless sensor networks continue to grow. So the need for effective security mechanism is important. Because sensor networks may interact with sensitive data and operate in open and unprotected environment, security is a crucial concern.Trust management helps to improve the security of wireless sensor networks. Various methods have been proposed for trust management in wireless sensor networks. An energy efficient hierarchical trust management scheme is proposed here which reduces the energy consumption rate of sensor nodes by calculat ing the trust values on demand and also the system is not collapses even if the cluster head is compromised. The trust management scheme is applied to both trust based geographic routing and trust based intrusion detection. Trust based geographic routing increases the packet delivery ratio compared with normal routing and trust based intrusion detection helps to identify the malicious nodes effectively.

Blockchain-Enabled Secure and Efficient Data Sharing Scheme for Trust Management in Healthcare Smartphone Network

“…To our knowledge, only a comprehensive trust management strategy, Reputation-based Framework for Sensor Networks (RFSN) 28 ) presented by Ganeriwal and Srivastava, for sensor networks. Reputation-based trust management solutions 29 , 30 have several drawbacks, including IoMT resource constraints. Hence, the proposed work implemented a lightweight, reliable Cluster-based Hierarchical Trust Management Scheme (CHTMS) to overcome the resource constraints issues.…”
