JiST: an efficient approach to simulation using virtual machines

Abstract

Discrete event simulators are important scientific tools and their efficient design and execution is the subject of much research. In this paper, we propose a new approach for constructing simulators that leverages virtual machines and combines advantages from the traditional systems‐based and language‐based simulator designs. We introduce JiST, a Java‐based simulation system that executes discrete event simulations both efficiently and transparently by embedding simulation semantics directly into the Java execution model. The system provides standard benefits that the modern Java runtime affords. In addition, JiST is efficient, out‐performing existing highly optimized simulation runtimes. As a case study, we illustrate the practicality of the JiST framework by applying it to the construction of SWANS, a scalable wireless ad hoc network simulator. We simulate million node wireless networks, which represents two orders of magnitude increase in scale over what existing simulators can achieve on equivalent hardware and at the same level of detail.

Enhancements of IEEE 802.11p Protocol for Access Control on a VANET Control Channel

“…In order to establish wether the proposed back-off mechanism really has a positive impact and with the goal of setting the best value for certain parameters, we have turned to the Java in Simulation Time (JiST) environment and to its Scalable Wireless Ad hoc Network Simulator (SWANS) package [14].…”

Degradation of Transmission Range in VANETs caused by Interference

“…To sum up this discussion, we have identified the following sources of packet loss 3 and hence transmission range degradation:…”

“…For our simulation study we use JiST/SWANS [4], [3] with the extensions from the University of Ulm. The additional STRAWpackage offers a integrated mobility model, enabling the simulated network nodes to move on streets.…”

TraffCon: an intelligent traffic control system for wireless vehicular networks

“…In order to evaluate the proposed solution the Java in Simulation Time / Scalable Wireless Ad hoc Network Simulator (JiST/SWANS) is used in conjunction with the Street Random Waypoint (STRAW) -vehicular mobility model for network simulations [26,27,28]. The vehicular mobility model employed by the simulator uses real world road maps as seen in figure 5.…”
