Risk Assessment Algorithm in Wireless Sensor Networks using Beta Distribution
This is an incremental improvement for wireless sensor network security, focusing on trust and risk management.
The authors tackled risk assessment in wireless sensor networks by introducing a Beta distribution to weight trust factors, presenting simulation results for comparison with their previous work.
This paper introduces the Beta distribution as a novel technique to weight direct and indirect trust and assessing the risk in wireless sensor networks. This paper also reviews the trust factors, which play a major role in building trust in wireless sensor networks and explains the dynamic aspects of trust. This is an extension of a previous work done by the authors using a new approach to assess risk. Simulation results related to the previous work and to the new approach introduced in this paper are also presented for easy comparison.
