Abstract: With wireless communication increasingly becoming popular and convergent, service providers have to continuously upgrade their networks in order to support increasing demand for bandwidth. In this regard communication in terahertz band is considered as an indispensable technology which assures data rate needs of upcoming wireless networks. In this study, a modified waterfilling algorithm is proposed for multi-user system with an objective to perform optimal resource allocation. This improved model enhances system performance in contrast to conventional scheme and attains largest possible capacity. Compared to conventional scheme, altered waterfilling model is deployed in multi-user system to evaluate data rate with distance consideration. We obtain power allocated and data rate using the algorithm and based on simulation results we indicate that proposed researcher outperforms existing technique.
