Reputation Systems
Abstract
In this thesis we provide an overview of current research on reputation systems in wireless sensor networks. Several proposals are reviewed and compared. In the second part of our research, we developed a universal multipurpose framework for wireless sensor network simulations and implemented selected proposals. We defined a set of tests and evaluated reputation systems with respect to overall network performance, energy consumption and resistance against presence of selfish and malicious nodes. Based on our observations we propose a new reputation system for protecting data integrity in wireless sensor networks. We provide complete simulation results and recommendations for further research.
