Feasibility-study of a multiplexing strategy in road transport informatics for short range MRNs
W. Kremer, R. Hager · 2002
Several different strategies for statistical multiplexers are investigated and compared by means of simulation in a real-time environment. According to special applications in the field of road transport informatics in short-range mobile radio networks (SR-MRNs), the different message types and their characteristics (e.g., arrival rate, real-time, amount of data, etc.) are described. A novel adaptive priority-oriented multiplexing algorithm called APS (adaptive priority scheduling) is examined with respect to its behavior in comparison to common strategies. The efficiency of APS compared with common strategies depends on the applications and their traffic load. APS never reduces the system performance, and, if several applications with hard time constraints have to be served simultaneously, APS will increase the performance.>
