Abstract: The delay in transmitting data from one point to the other has necessitated to introducing enhancing cognitive radio spectrum sensing using intelligent routing technique. This can be achieved in this manner; characterizing the base station, determining the interference, congestion, high bit error rate, from the characterized network that prevents spectrum sensing and causes network failure, designing a fuzzy based rule for cognitive radio spectrum sensing that would reduce high bit error rate and congestion in the system and designing a SIMULINK model for enhancing cognitive radio spectrum sensing using intelligent routing technique. The results obtained for highest conventional congestion is 2.21 while that when intelligent routing is incorporated is 1.946 at day seven. Similarly highest conventional bit error rate occurred at day one is 0.000084bits while the highest bit error rate when an intelligent routing occurred at the same day one is 0.00007394bits. With these results obtained, it shows that using intelligent routing gives better network performance in terms of transmitting data fast than when conventional method is applied in the system.

I.INTRODUCTION

The passage of data from the sending point to the receiving point can be delayed by high bit error rate in cognitive radio. This issue of delay in data movement from one point to the other is addressed by intelligent routing technique. In Cognitive radio paradigm, wireless users are classified into two categories based on whether they are licensed to use a particular band or not, the primary users are the licensed band and secondary users are the unlicensed users. Cognitive radio recognize radio spectrum that are unused by Primary User (PUs) and intelligently allocate these spectrum to Secondary User (SUs). So unused radios spectrum is called spectrum opportunity and also known as white space (Shahzad et al, 2010) or spectrum hole (Mansi and Gajanan, 2011).Secondary Users are allowed to opportunistically use the spectrum as long as they do not cause harmful interference to active Primary Users
