A Trust Management Scheme for Enhancing Security in Pervasive Wireless Networks

In a pervasive wireless network, malicious nodes can initiate attacks to well-behaved nodes. This paper argues that our recently proposed probabilistic trust management scheme for pervasive computing can be used in pervasive wireless networks to provide protection against few typical attacks usually targeted at such systems. Simulation experiments are provided to assess the achievement of the stated goal. The performance metric used is the average packet loss ratio, representing the ratio of packets lost to the total packets generated in a certain time period.
