ABSTRACT 

Wireless sensor networks provide ubiquitous computing systems in various open environments. In the environment, sensor nodes can easily be compromised by adversaries to generate injecting false data attacks. The injecting false data attack not only consumes unnecessary energy in en-route nodes, but also causes false alarms at the base station. To detect this type of attack, a bandwidth-efficient cooperative authentication (BECAN) scheme was proposed to achieve high filtering probability and high reliability based on random graph characteristics and cooperative bit-compressed authentication techniques. This scheme may waste energy resources in en-route nodes due to the fixed number of forwarding reports. In this paper, our proposed method effectively selects a dynamic number of forwarding reports in the source nodes based on an evaluation function. The experimental results indicate that our proposed method enhances the energy savings while maintaining security levels as compared to BECAN.
