Sky Station Stratospheric Disaster Recovery System by Appling HAPs and Cooperative Communication Protocols

In this paper, the two well-known cooperative strategies are known as Amplify And Forward (AAF) and Decode And Forward (DAF) strategy will be considered, which achieves diversity by using Maximal Ratio Combining (MRC). The study presents a techno economic analysis of wireless technologies in sky station stratospheric platform, called third generation (3G) implemented in HAPs and cooperative protocol. Objectives of this study are to investigate the high-capacity, and large coverage capabilities of WCDMA for the provision of voice and data emergency communications system during unforeseen events such as natural disasters. In this paper, the impact of applying of HAP and different types of cooperative protocols on cell capacity and coverage is presented. The simulation results show that system parameters such as capacity, Coverage increase and lowering the bit-error rate with rapid decrease in the value of Eb/ No and system becomes more reliable and efficient. HAPs systems with cooperative protocol have a vital role to play in the prosecution of disaster recovery campaigns. Keywords—Capacity, Disaster, HAPs, Stratospheric, Cooperative Communication, WCDMA.
