The performance of typical non-real-time scheduling mechanisms in wireless communication system

This article discusses characteristics, performance of the scheduling algorithm in the resource allocation. The background of the study of frequency resource allocation algorithm is in free space, ideal channel estimation of the wireless network environment, considering the location information of users (i.e. the channel conditions of the user, etc.). This article does the research through modeling, the theoretical analysis of the calculation and simulating the real network environment. In addition, this article analyzes, describes and compares the typical resource allocation algorithms, and describes the improved algorithm. The main algorithms include Round Robin (RR), Maximum Signal to Noise ratio(Max S / N), Proportional Fairness (PF).
