methods which are highly energy efficient, but it does not bother about network security. Hence in this paper we are comparing different wireless routing protocols and find best protocol to create energy efficient Cognitive Radio network (CRN) model having attacker nodes in it. Finally energy consumption comparison graph was generated between those routing protocols and finds the efficient model i.e. the creation of energy efficient CRN model.

1. INTRODUCTION Cognitive radio is a Software-defined radio that can able to access unused radio spectrum holes efficiently. The definition adopted by Federal Communications Commission (FCC):“Cognitive radio: A radio or system that senses its operational electromagnetic environment and can dynamically and autonomously adjust its radio operating parameters to modify system operation, such as maximize throughput, mitigate interference, facilitate interoperability, access secondary markets.” Cognitive radio (CR) techniques provide the capability of detecting spectrum holes and sharing the spectrum in an opportunistic manner. DSA techniques can select the best available channel from the spectrum pool for CR devices to operate [4]. More specifically, CR enables secondary users (SUs) to perform a series of operations as follows: 1) spectrum sensing to predict what spectrum is available and recognize the presence of the primary user (PU) when a PU reoccupies the licensed channel; 2) spectrum management to select the best available channel from the spectrum pool for special services; 3) spectrum sharing to coordinate access to all available channels with other SUs; and 4) spectrum mobility to vacate the channel as soon as possible when a PU is detected [4]. Spectrum sensing is one of the most important components in the cognition cycle .Routing protocols plays an important role to choose an efficient CRN model. Hence in this paper we are going to compare the reactive, Proactive
