标题:基于消息传递接口的分布式无线传感器网络仿真与分析

摘要】无线传感器网络(WSN)被许多行业使用,从环境监控系统到NASA的太空探索计划,因为它使社会能够以更少的成本和更少的维护来监控和预防问题。本文档旨在提出和分析使用基于最近邻居/网格的套接字体系结构的有效的进程间通信(IPC)体系结构。为了提高WSN的安全性,还使用了AES加密算法的并行版本。首先,将提出的体系结构与其他完善的体系结构进行比较和对比。接下来,阐明了AES加密算法的优缺点。 C中的消息解析接口(MPI)库用于通信,而OpenMP用于并行化加密算法。接下来,对从多个模拟获得的结果进行分析。最终得出结论,具有AES并行加密的基于网格的IPC体系结构可帮助WSN保持通信安全性,同时又可降低运营成本和功耗。

Title: Simulation and Analysis of Distributed Wireless Sensor Network using Message Passing Interface

[abstract]  Wireless Sensor Networks (WSN) are used by many industries from environment monitoring systems to NASA’s space exploration programs, as it has allowed society to monitor and prevent problems before they occur with less cost and maintenance. This document aims to propose and analyze an efficient inter process communication (IPC) architecture using a nearest neighbor/grid based socket architecture. A parallelized version of the AES encryption algorithm is also used in order to increase the security of the WSN. First the proposed architecture is compared and contrasted against other well established architectures. Next, the benefits and drawbacks of the AES encryption algorithm is elucidated. The Message Parsing Interface (MPI) library in C is used for the communication while OpenMP is used for parallelizing the encryption algorithm. Next an analysis is performed on the results obtained from multiple simulations. Finally a conclusion is made that the grid based IPC architecture with AES parallel encryption helps WSNs maintain security in communication while being cost and power efficient to operate.
