Abstract :
The ever increasing demand for multimedia services has led to the extensive use of modern wireless mesh networks, where the transmitted signals arrive to the final destination through cooperative relay nodes. Due to the increased demand for bandwidth, these networks operate at frequencies above 10 GHz where rain attenuation is the dominant fading mechanism. In this paper, the outage performance analysis of a dual hop transmission is presented and a physical propagation model is calculated. Extended numerical results investigate the impact of various operational, geometrical and climatic parameters to the outage analysis.
