我在 VACaMobil 中遇到了一些 TCP 问题。我正在使用 Inet 中构建的两个 TCP 模块：TCPBasicClientApp 和 TCPEchoApp。前者作为客户端工作，而前者作为服务器工作。
模拟中的汽车数量（模块名称为“coche”）为100，并发传输有5个：
CLIENT SERVER
Car 0 --> Car 99
Car 1 --> Car 98
Car 2 --> Car 97
Car 3 --> Car 96
Car 4 --> Car 95
我也在使用三种路由协议：AODV、DYMO 和 OLSR。但是，无论我运行什么配置，模拟中都会出现这样的错误：
Error in module (TCPBasicClientApp) Highway.coche[*].tcpApp[0] (id = 35) at event #49519, t = 166: IPvXAddressResolver: module 'coche[98]' not found.
在这种情况下，使用 AODV，汽车 1 无法与汽车 98 通信。我了解到 VACaMobil 在一段时间后删除了一些汽车，而它正在创建超过 100 的其他汽车，例如“coche[110]”、“coche[115]” ]“， ETC。
我不明白为什么它一直在删除和创建节点；我认为 VACaMobil 确实产生了恒定数量的车辆。
我怎样才能解决这个问题？任何帮助表示赞赏。
