Performance Comparison Between Traditional Network and Broadcast Cognitive Radio Networks Using Idle Probability

Abstract

In this paper, we suggest a broadcast routing protocol for multi-hop mobile Ad Hoc CRN based on the connotation of the shortest path tree (SPT). The suggested algorithm uses the probability of success (POS) metric in executing the channel customize process. Under different network parameters within Rayleigh fading channels, the performance of SPT broadcast CRN with POS scheme is compared with the performance of maximum data rate (MDR), maximum average spectrum availability (MASA) and random channel assignment schemes. After simulation, SPT broadcast CRN with POS scheme was seen to pretend the best execution versus other schemes. The network’s performance improved with the progressing in the value of idle probability (\( {\text{P}}_{\text{I}} \)) because the primary user’s (PU) traffic load is low when the value of \( {\text{P}}_{\text{I}} \) is high. In addition, the performance of SPT broadcast CRNis compared with the performance of traditional network and notice that it is nearing the latter is performance as the value of \( {\text{P}}_{\text{I}} \) increases.
