摘要

如何高效、优化地部署传感器网络已成为当今社会的重要课题。传感器网络基本上是由配备传感器、控制器和通信模块的多个节点组成的基础设施。来自相邻节点的干扰使得通信系统难以达到所需的吞吐量,也使得网络行为难以预测。CupCarbon是一个无线传感器网络(WSN)模拟器,最近由实验室stic的研究人员开发,以更好地分析和理解WSN。本文提出了一种基于正交频分复用(OFDM)的物理层在仿真器中的优化集成方法,并考虑了无线通信中网络干扰的影响。为了灵活准确地表示干扰,采用稳定分布函数来建模。这允许更好地估计信道条件,以考虑信道条件和网络中干扰的密度。

Integration of OFDM Based Communication System with Alpha-Stable Interference using CupCarbon Simulator
Deploying sensor networks in an efficient and optimal way has become an important topic these days. A sensor network is basically an infrastructure which consists on number of nodes equipped with a sensor, a controller and a communication module. Interference from the neighboring nodes makes it difficult for a communication system to achieve the required throughput and also makes it difficult to predict the network behavior. CupCarbon is a wireless sensor network (WSN) simulator, recently developed by researchers of Lab STICC, for a better analysis and understanding of WSN. In this paper, we present an optimal way to integrate a PHY layer based on Orthogonal Frequency Division Multiplexing (OFDM) in the simulator and we have also considered the network interference impact in wireless communication. For a flexible and accurate representation, interference is modeled by alpha-stable distribution function. This allows the better estimation of channel conditions to take into account the channel conditions and the density of interferers in a network.
