Cognitive radio networks improve spectrum utilization by ‎sharing licensed spectrum with cognitive radio devices. In ‎cognitive radio ad hoc networks the routing protocol is one ‎of the most challenging tasks due to the changes in ‎frequency spectrum and the interrupted connectivity ‎caused by the primary user activity. In this paper, a multi‎path activity based routing protocol for cognitive radio ‎network (MACNRP) is proposed. The protocol utilizes ‎channel availability and creates multiple… CONTINUE READING

Key Quantitative Results

  • We have found that the ‎MACNRP scheme results in 50% to 75% reduction in ‎blocking probability and 33% to 78% improvement in ‎network throughput, with a reasonable additional routing ‎overhead and average packet delay.
  • We have found that the MACNRP scheme results in 50% to 75% reduction in blocking probability and 33% to 78% improvement in network throughput, with a reasonable additional routing overhead and average packet delay. Due to the successful reduction of collision between primary users and cognitive users, the MACNRP scheme results in decreasing the path failure rate by 50% to 87%.
  • Through simulations, we showed that the proposed protocols increase the network throughput on average by 33% above FTCARP protocol and 78% over the D2CARP protocol. Also, the proposed protocol succeeded in reducing the blocking probability and the average increasing rate of the blocking probability by 75% below the D2CARP protocol and 50% below the FTCARP protocol.
