Enhancing Throughput Efficiency of Adhoc Wireless Networks Using Cognitive Radio Approach

The goal of the paper is to enhance the throughput efficiency of wireless adhoc networks. An adhoc network is a collection of wireless mobile hosts forming a temporary network without the aid of any established infrastructure or centralized administration. Each node is considered to be alike here. It is needed to introduce some intelligence to the adhoc networks in order to improve their throughput efficiency. The concept of Cognitive Radio (CR) has been employed to achieve this. CR enabled devices are ´clever´ and can listen to the surrounding wireless environment and can select appropriate frequency band, modulation scheme or specific power level as per the requirement. In this way an ability of self decision making can be incorporated in the wireless adhoc networks. Our work presented in this paper shows an initial direction towards the future research possibilities for the implementation of the CR for self aware and self organized adhoc wireless networks.
