使用J-SIM模拟无线传感器网络的研究

Research of Wireless Sensor Network Simulation in J-SIM

无线传感器网络由于在军事通讯、国土安全、环卫环保、交通监察等诸多领域的应用而成为目前IT领域的研究热点之一。对于研究者则需要一个仿真度高、具有高可靠性和扩展性的仿真平台以验证自己研究的结果的科学性。介绍了一个全新的完全开源的、跨平台的使用Java开发的传感器网络模拟平台J-SIM,并以目前无线传感器网络比较流行的S-Mac协议为例使用J-SIM进行了传感器网络的模拟。J-SIM相对于NS2使用简单方便,而实验结果证明,J-SIM可以得到与NS2同样正确的模拟结果,J-SIM的性能也比NS2稳定得多。

Wireless sensor networks （WSNs） have become one of the most popular research areas in IT, because they have found application domains in battlefield communication, homeland security, pollution sensing and traffic monitoring and so on. And for researchers, they need a simulation frameworks for carrying out high - fidelity WSN simulation. In this paper, introduce a modeling, simulation, and emulation framework for WSNs, J - SIM, an open - source, operation system independent network simulation environment that is developed entirely in lava. And then take S- Mac for example to simulate WSN using J - SIM. The simulation study indicates the proposed WSN framework in J - SIM is much more scalable than NS2.
