Performance evaluation of dynamic spectrum assignment and access technologies

Implementing dynamic spectrum assignment and access technologies in heterogeneous wireless networks may lead to considerable improvement in spectrum usage and quality of service. In this paper we evaluate the performance of SINR-based dynamic spectrum assignment and access algorithms using simulation. We compare network capacity values gained using these two algorithms with the one gained using SINR-based vertical handover algorithm. We show that dynamic spectrum assignment and access algorithms have considerable gain in network capacity compared to handover algorithm. These performance evaluation results prove the efficiency of the dynamic spectrum assignment and access technologies.
