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 rapid development of sensor technology, sensor technology has been widely concerned and applied in more and more fields. However, due to the limited application characteristics of sensor networks, many problems exist in the modeling and simulation of sensor network. Effective design is very important for a complete sensor network model. Using PtolemyII-based simulation tools, the sensor network can be effectively modeled and simulated. This paper discusses the shortcomings of current sensor network modeling and simulation platform, introduces how PtolemyII uses hierarchical heterogeneous design to solve the problem of sensor network modeling, as well as the sensor network modeling and implementation principle of this design idea. Based on PtolemyII A complete sensor network computing model based on positioning applications.
