Experiment Operation Record

为了早点看到病毒的传播功能是否加入场景，将最早出现的车辆ID为0DEtoFR.0的车辆设置为感染状态，同时为了保证病毒会被传播出去将ID为CNA____NBNA_0的公交也设置为感染状态。

Luxembourg SUMO Traffic (LuST) Scenario

数据集场景分析

卢森堡数据集分析，该数据集共有4中场景：

Mobility: shortest path with rerouting.

lab2：system calls

Preparation

Read chapter 2 and xv6 code: kernel/proc.h, kernel/defs.h, kernel/entry.S, kernel/main.c, user/initcode.S, user/init.c, and skim kernel/proc.c and kernel/exec.c

In the last lab you used systems calls to write a few utilities. In this lab you will add some new system calls to xv6, which will help you understand how they work and will expose you to some of the internals of the xv6 kernel. You will add more system calls in later labs.

XV6:a simple,Unix-like teaching operating system

chapter 1 Operating System interfaces

内核：一个为程序提供服务的特殊程序。（kernel: a special program that provides services to running programs）

6.S08-lecture 3 -OS organization and System Call

操作系统隔离性（isolation）

操作系统需要隔离性，在应用程序和操作系统之间需要强隔离性。

实现隔离性需要硬件支持：

• user/kernel mode
• page table 或者说 virtual memory

XV6的运行以及退出

xv6的运行

进入到xv6项目文件夹下，输入make qemu命令运行，运行后出现一下信息

Effects of Social Network Structure on Epidemic Disease Spread Dynamics with Application to Ad Hoc Networks

Abstract

In this article, we briefly survey the literature on network structure effect on disease spread models. Subsequently, we discuss an SEIR based epidemic model for different levels of aggregation of population. we propose two security architectures for these networks based on several design criteria including scalability, power, and computation limitations.

简单的调查了一下网络结构对于病毒传播的影响，讨论了对于不同聚集程度人群的模型。基于网络的各种安全设计标准包括伸缩性、性能、计算能力限制提出了2种安全的架构。

前言：测试时候注意事项

1.完成程序，添加配置

在完成程序之后，需要在Makefile中添加配置，这下面添加的是copy.c
