我对静脉碰撞的产生有疑问。我正在运行示例场景,仅发送信标,没有RSU,也没有阴影。我重复仿真,改变信标间隔(从每秒1个信标(1秒)到每秒30个信标(0.033秒))和传输功率(从5 mW到40 mW),以查看冲突的影响。我所期望的是,使用更少的txPower发生很少的冲突,如果txPower值更大,则会发生更多的冲突。但是我得到了一些不同的碰撞值,例如,这是我所做的一些模拟的输出:
[*] beaconInterval: 0.5 txPower: 5 Collisions: 0 Total Losts: 0 Received: 114723
[*] beaconInterval: 0.5 txPower: 6 Collisions: 0 Total Losts: 0 Received: 128635
[*] beaconInterval: 0.5 txPower: 7 Collisions: 3 Total Losts: 3 Received: 135691
[*] beaconInterval: 0.5 txPower: 8 Collisions: 0 Total Losts: 0 Received: 142921
[*] beaconInterval: 0.5 txPower: 9 Collisions: 0 Total Losts: 0 Received: 153000
[*] beaconInterval: 0.5 txPower: 10 Collisions: 0 Total Losts: 0 Received: 158094
[*] beaconInterval: 0.5 txPower: 11 Collisions: 0 Total Losts: 0 Received: 166895
[*] beaconInterval: 0.5 txPower: 12 Collisions: 0 Total Losts: 0 Received: 172933
[*] beaconInterval: 0.5 txPower: 13 Collisions: 13 Total Losts: 13 Received: 178446
[*] beaconInterval: 0.5 txPower: 14 Collisions: 745 Total Losts: 1683 Received: 182008
[*] beaconInterval: 0.5 txPower: 15 Collisions: 0 Total Losts: 0 Received: 192333
[*] beaconInterval: 0.5 txPower: 16 Collisions: 0 Total Losts: 0 Received: 196579
[*] beaconInterval: 0.5 txPower: 17 Collisions: 0 Total Losts: 0 Received: 203119
(例如)用2个信标秒数和14 mW的txPower进行745次冲突,并以相同的间隔和更大的txPower进行0次冲突是正常的吗?这些结果如何解释?
[附加信息:代码]
在文件 resultados.txt 中,您可以看到我得到的部分结果。在此文件和代码中,我将Ftx称为信标速率(beaconInterval由1 / Ftx获得),将Ptx称为txPower。
