With the growth of increasingly complex in wireless ad-hoc networks, performance modeling and evaluation play a crucial part in their design process to ensure successful deployment and exploitation in practice. Compared with the actual implementation (testbeds), simulation has become a valuable tool, which allows studying large scale systems that cannot be built practically. However, most simulators currently used for such networks are intended to evaluate individual routing protocol, which should be extracted from the source code and rewritten in accordance with the simulator’s requirements. Thus, in this paper, we design a new wireless ad-hoc network simulator, called Time Step-based Wireless Ad-hoc Network Simulator (TimSim). It is intended to facilitate the migration of simulation code to real devices via providing useful APIs with real device driver. We use a discrete event processor with time step-based feature as the simulating engine, and the data can be transmitted in bit-level. A unique feature of TimSim is its ability to support the simulation of multi-thread programming. Additionally, we import database access to store the simulation information. Extensive experiments have been conducted to evaluate the efficiency of TimSim. Furthermore, a case study on a real system has been presented to illustrate its practicability.
