Real-Time Scheduling Algorithm Based on Dynamic Priority for Multi-data Transmission
In response to the demands of heterogeneous data acquisition, data transmission effectiveness and reliability in emergencies as well as environmental wireless monitoring etc., this paper presents a data transmission queue optimization algorithm based on dynamic priority. The algorithm dynamically assign priorities to different data according to their importance, historical transmission data and other factors, as to make the best use of current limited bandwidth of communication to ensure data transmissions real-time degree and effectiveness. Theoretical analysis and simulation show that the algorithm makes quite improvement when applying to data transmission in the environment of non-stable communication link.
Keywords: dynamic priority, task scheduling, data transmission queue
