Performance evaluation of Nash Bargaining Power sharing algorithm for integrated cellular phone system

This paper proposes an integrated cellular phone system with a cognitive radio sensor node (CRSN) to combat terrorism without establishing separate sensor network architecture for explosive trace detection. In this approach cellular phone user is considered as primary user (PU) with the permission to utilize the license band and CRSN may be designed in underlay mode to operate in the emergency situation simultaneously with the PU to send sensory information about the presence of explosives to the nearest base station. In this application CRSN would act as secondary user (SU) and share power of its own PU to send the emergency information that in turn causes interference and minimizes the PU's quality of service (QoS). The challenging issue is to share the allocated power of the PU with SU sustaining the link connection of the PU with the base station. We have used Nash Bargaining Power Control (NBPC) technique to search optimal powers at different distances from the base station for both the PU and SU of the proposed integrated cellular phone system and ultimately control the power of both PU and SU in the emergency environment. A comparative analysis of NBPC has been done with the traditional power control scheme called Signal to Interference plus Noise Ratio (SINR) Balancing Power Control (SBPC). Simulation results in MATLAB 2010b show that NBPC outperform SBPC.
