Network calculus is a promising theory for analyzing and modeling networks based on min-plus algebra. Using network calculus theory, we propose formulas of arrival curve and service curve for end-to-end communication, build the corresponding time model, and derive the communication delay formulas for two scenarios of the model respectively. Then we take fat tree topology, which is widely used in Infiniband...
During the process of communication in WLAN, delay and packet loss frequently happens,In order to solve this problem we simulate with NS2 for better communication strategies.According to the relationship between topological range and trasmission speed, number of nodes and performance of delay,we assign dynamic transmission speed to acquire an optimal transmission speed and topological range and communication...
