A Survey on Dynamic Spectrum Access (DSA) and Management in Vehicular Environment: The Case Study in Tanzania

Abstract

This paper describes the survey approach to building a high-quality of dynamic Spectrum access (DSA) and management in vehicular environment networks in Tanzania as one of the ways of mitigating the shortage of access. Frequency spectrum is a limited resource for wireless communications and may become congested owing to a need to accommodate the diverse types of air interface used in wireless networks. The objective of this paper is to meet these growing demands by provide a brief overview of the cognitive radio technology. The paper explains the existing work and challenges in spectrum sensing. It describes the next network functionalities: spectrum management, spectrum mobility and spectrum sharing and further explains how next network functions can be implemented.
