Cooperative Sensing Approach in Cognitive Radio Network-A Review Paper

Abstract

Radio Spectrum is considered as a base line in Wireless communication network, due to its important role as a transmission medium; and according to the rapid improvement in the technologies which deal with radio spectrum; cognitive radio raised as a promising solution for solving the problem of radio spectrum scarcity. Cognitive radio is based on spectrum sensing as appropriate tool to study surrounding environment in order to illustrate the suitable scenario for sharing spectrum between users. Cooperative sensing is the most sophisticated approach in spectrum sensing depends on base of sharing information to eliminate error in spectrum sensing mechanism. This paper is a review paper. It discusses Cooperative sensing approach features in cognitive radio
