Trust-Based Content Distribution for Mobile Ad Hoc Networks

Free registration required

Executive Summary

Mobile ad hoc networks will enable future mobile users to share and distribute content using direct mobile-to-mobile wireless connections. Since such networks will need to be based on an open environment, selecting the appropriate nodes for interactions is a major challenge, especially when some of the nodes may be misbehaving. Considering that mobile devices have limited resources (i.e., available battery power, processing power and the available bandwidth), interacting with misbehaving nodes will waste these resources and reduces the usable time of mobile devices. Trust-based solutions provide a method to select neighbours based on their trust value which is derived from previous interactions.
