A Global System for Mobile Communication with Prevention to Reduce Higher Signal Strength in CRN

The spectrum allocation is the big problem in Cognitive Radio Network (CRN) and the reason is the unreliable deeds of Secondary Users (SU). The Secondary Users (SU) are reliable users and licensedusers in the network. These users are not responsible for malicious activities in CRN. The secondary users are using the free spectrum bands and also sometimes use the spectrum holes. The high strength of the attacker is also disturbing the actual performance PU as well as SU. This paper proposed a novel Global System for Mobile Communication with Prevention (GSMP) scheme to reduce the higher signal strength of malevolent nodes. The malevolent node transmits data from full of energy that passed over the actual receiver in the network. The mobile devices or nodes maintain the connection with others by sending control packets and after that exchanging information through established connections. The nodes are unknown from the attacker because it forwards the fake messages of the route in high strength. The attacker is detected by its strength i.e. it uses for forwarding of bogus packets that consumes the available bandwidth and by that not sends the data to the next neighbor node or sends up to the destination in the network. The proposed GSMP scheme is identified as the high signal strength at any intermediate node in the network. The higher signal strength again reaches normal by wedge its source i.e. attacker. The concert of propose GSMP is measured by different performance metrics.
