Abstract:

A trust-based secure routing model was put forward for defending against the selective forwarding attack on routing in cognitive radio networks.Based on monitoring results of nodes' forwarding behavior, trusts were built in order to identify malicious nodes.For the characteristic that routing selection must be closely collaborative with spectrum allocation, a route request piggybacking available spectrum opportunities was sent to non-malicious nodes during the routing discovery phase, and routing decisions were performed according to delays and available paths' trusts calculated from nodes' trusts during the routing selection phase.At t e time, different responses were made to service requests from nodes in different trust levels, and more severe penalties were taken for malicious behavior from non-trusted nodes, which can promote nodes’ cooperation in routing.Simul ion results and analysis show that under selective forwarding attack the proposed model has advantages in network throughput and end-to-end delay over the existing models.

Key words: cognitive radio network, selective forwarding attack, trust, routing
