在ONE使用External Contact Trace

以Dieselnet数据为例，使用toolkit目录下的转换脚本将其转换成ONE能够识别的格式。以下为示例配置文件：

 1 Scenario.name = diesel_net

 2 Scenario.simulateConnections = false

 3 

 4 #Group settings

 5 Scenario.nrofHostGroups = 1

 6 Group.nrofHosts = 23

 7 Group.nodeLocation = 10,10

 8 

 9 Group.movementModel = StationaryMovement

 Group.nodeLocation = 100,100

 Group.bufferSize = 150M

 

  

 Events.nrof = 2

 Events1.class = ExternalEventsQueue

 Events1.filePath = traces/2007-10-23-one.txt

 

 ## Message creation parameters

 # Class of the event generator, it's required or no message will be created!

 Events2.class = MessageEventGenerator

 # (following settings are specific for the MessageEventGenerator class)

 # Creation interval in seconds (one new message every 25 to 35 seconds)

 Events2.interval = 25,35

 # Message sizes (50kB - 150kB)

 Events2.size = 500k, 1M

 # range of message source/destination addresses

 Events2.hosts = 0,23

 # Message ID prefix

 Events2.prefix = M

后记：该配置下（default_settings & diesel_settings, Epidemic Routing）的消息成功递交率仅为：

5M:0.0349

150M:0.2613

1000M:0.3194

可能的原因: 1,网络过于稀疏导致contact graph不连通; 2,节点移动速度缓慢或者移动的节点过少，导致消息不能在RTTL内完成传输。
