Abstract :
This paper focuses on the security problem in unreliable wireless ad hoc networks when involving network coding. A typical example of misbehaviors by bad nodes is presented to show the misbehavior propagation problem of network coding. To reduce the influence of bad nodes, we propose to combine network coding with trust scheme. In our trusted network coding, a trust model is established according to the behavior observation procedure. We take COPE (a typical network coding-based protocol) as a baseline to implement trusted network coding. Simulation results show that our trusted network coding performs much better than conventional network coding without trust scheme.
