基于PtolemyII的传感网络仿真研究

Sensor Networks Simulation Based on PtolemyII

随着传感器技术的飞速发展,传感器技术在越来越多领域得到了广泛的关注和应用;然而,传感器网络不同的应用特性限制使基于传感网络的建模与仿真面临诸多问题。有效的设计对一个完善的传感网络模型非常重要,使用基于PtolemyII的仿真工具能够有效地对传感网络进行建模仿真。探讨了目前传感网络建模仿真平台的不足,介绍了PtolemyII如何运用层次异构设计思想解决传感网络的建模问题,以及该设计思想的传感网络建模与实现原理;并基于PtolemyII实现了一个完整的基于定位应用的传感网络计算模型。

With the development of sensor technology today, it is used in more and more fields. Many challenges arise when trying to model and simulate the networks of these sensors, because the sensors have defferent capabilities and constraints. A complete model of a sensor network is needed to improve its design. Using a modeling and simulation tool called PtolemyⅡ models of these networks can be better constructed. The research clone in this paper will discuss the shortage of the current modeling and simulation platforms, introduce how PtolemyⅡ solves the problem by hierarchical heterogeneity, and describe the design principles implemented in the PtolemyⅡ. At last, a complicated sensor network based on tracker application is modeled and simulated in the PtolemyⅡ.
