Multi Objective Coordination Approach for Resource Utilization in Heterogeneous Cognitive Radio Network

Abstract

The Heterogeneous network has the advantage of utilizing multiple wireless architectures to exchange information over a wireless medium. In coordination with multiple devices, long range data transmission is achieved. The advantage of multiple network utilization has brought out the significance of higher service applications for any network device with the advantage of using multiple networks for communication. In this network, the demand for proper resource utilization arises due to a shift to multiple networks. As the network switches from one network to another, and observed issues like fairness, power, spectrum utilization in the resources are varied, which impacts the flow of data. Hence it is required to optimize the resource utilization to achieve a fair and efficient communication. Towards achieving the objective of fairness in an heterogeneous network with cognitive devices, a multi objective coordination approach for optimal resource utilization is proposed. The resource utilization problem is defined by an effective spectrum utilization among the network users. The simulation results show a significant improvement in resource utilization compared to conventional approaches.
