There is an increased usage of wireless communication for personal use, commercial use etc. Nowadays Cognitive Radio has become the prime topic of interest in wireless network. It is an intelligent radio technology, which easily adapts to the network and automatically detects the vacant channels which are available in a wireless spectrum. It then changes the transmission parameters enabling concurrent communica-tions thereby improving the radio operating behavior. VoIP mobile applications are used worldwide for making audio and video calls using internet. But they face many disadvantages such as reflection of voice/echo, breaking of voice, delay in voice etc and have reduced quality with low Wi-Fi or 3g signals. Therefore we are designing an efficient and effective system to improve throughput and bit error rate of VoIP mobile applications by implementing them using cognitive radio networks.

“…Cognitive radios can implement function spectrum sensing in many ways. The two categories are co-operative spectrum sensing and non co-operative spectrum sensing [2] [3]. In cognitive networks, the most important consideration is given to the primary user compared to the secondary user.…”
