Survey on spectrum occupancy by using different techniques

Due to the fast development of wireless communication, the traffic between licensed and unlicensed users have raised because of more using up of the spectrum. The portable activity in 2010 was five conditions more important than that of an official figure made by the International Telecommunication Union (ITU) in 2005, and will additionally increment around 1000 circumstances in a period before 2020. Many researches has been made to reduce data traffic in terms of spectrum occupancy. Numerous methods were used in spectrum occupancy for sensing and predicting the spectrum. Data traffic is the quantity of data moving through a network in a certain period of time. Many spectrum occupancy methods are on hand and this paper provides a detailed survey information about various spectrum occupancy which has been proven to produce better result in reducing the data traffic.
