Abstract
A new methodology for controlling and managing a complex distributed communication system is presented here. A model which describes the real-time behavior has been proposed, together with the recommended alternative for its implementation. The research is based on a rational design approach, supported by a simulation study, for evaluating the relative performance of different strategies. The main problem is related to the constraints of signal observability by all distributed units. It creates an uncertainty gap which ends up in a non-coherent view of the system state by all its units. The uncertainty gap can be minimized by the creation of a new control architecture. The communication coordinator section in every unit should carry all of the mechanistic management activities, leaving only strategic decisions to the control section. Another promising method for reducing the uncertainty gap, is the integration of the reconfiguration technique into the distributed system, which leads to the adaptation of the system to the varying work profile. The simulation study indicated a potential bottleneck in the centralized scheduling approach, and recommended the dynamic allocation method as the prefered one. The minimal-queue unit is selected for running the new task, provided that the source unit queue has reached a threshold level above its average queue length.
This article is based on the Ph.D. thesis by J. Etkin, advised by Prof. D. Tabak, submitted as a partial fulfillment of the Ph.D. degree requirements at the Ben-Gurion University of the Negev, Beer Sheva, Israel. D. Tabak is an Abrahams-Curiel Professor (on leave).
