Improving Performance of Parallel Simulation Kernel for Wireless Network Simulations

For decades, simulations have been the means to study the behavior and analyze the performance of engineering, computer science, and military applications. In the sequential discrete-event driven simulations, the events are executed sequentially in an increasing order of their timestamp. Simulation of large complex applications using sequential simulators often turns out to be infeasible due to computer resource limitations. Parallelizing discrete-event simulation is acknowledged as the most promising approach for simulating large complex applications. Parallel discrete-event simulation refers to the execution of events from a single discrete-event simulation program in parallel. In this paper we focus on extracting parallel events for wireless ad hoc network simulations based on the distance and terrain information
