Performance Enhancement of Heterogeneous Complex Wireless Network for Communication Systems Using Optimization Techniques

The next generation wireless communication technology demands high data transmission rate and system capacity, cognitive radio is one of the technologies that utilizes the spectrum resources in a more efficient and fruitful way to improve the network performance of heterogeneous complex networks. However, achieving these is a challenging task when it is to deal with multiple heterogeneous networks having overlapping coverage and diversified requirements of the users. This Challenge can be overcome by efficiently selecting the network and reasonably allocating the ideal spectrum resources. The work in this dissertation aims to maximize the total bandwidth utilization while minimizing the total cost with the help of optimization techniques. The proposed work aims to modify the existing optimization techniques and apply it to enhance the performance of heterogeneous complex wireless networks for communication systems. Finally, the performance of traditional methods is compared and analyzed through experiments with the proposed methodology.
