A Generic Optimized Time Management Algorithms (OTMA) Framework for Simulating Large-Scale Overlay Networks

Recent evolutions in wireless networks will require more efficient use of the underlying parallel discrete-event simulation (PDES) synchronization protocols to accommodate the demand for large-scale network simulation. In this paper, we investigate underlying synchronization protocols to improve the performance of large-scale network simulators operating over PDES systems. We begin by proposing a generic optimized time management algorithms (OTMA) framework that combines the improved forms of synchronization protocols on a single platform. Particularly, for the proposed OTMA framework, we use the layered architecture approach to combine the optimized forms of conservative and optimistic time management algorithms. To support the implementation of the OTMA framework, a new m-LP (logical process) simulation model is proposed along with the varying parameters network topology that can show the implementation of different components of discrete-event simulation (DES).
