在模拟"groovy.lang.MissingPropertyException: No such property: ROUTING for class: org.arl.unet.sim.Simu

Question

我正在使用node.startup = {}中的仿真脚本中的node.startup = {}来通过在每个节点上发送routediscoveryntf来生成静态路由。我包含了所有标题，但仍未识别路由服务。

仿真脚本如下，所有节点的启动功能均相同

    //! Simulation: 5-node network
    import org.arl.fjage.*
    import org.arl.fjage.Agent.*
    import org.arl.fjage.RealTimePlatform
    import org.arl.unet.sim.*

    import org.arl.unet.Services
    platform = RealTimePlatform
    channel.model = ProtocolChannelModel
    channel.soundSpeed = 1500.mps           // c
    channel.communicationRange = 100.m     // Rc
    channel.detectionRange = 100.m         // Rd
    channel.interferenceRange = 100.m      // Ri
    channel.pDetection = 1                  // pd
    channel.pDecoding = 1                   // pc
    simulate {
      def n1 = node '1', address: 1, location: [0.m, 0.m, 0.m], shell: true, stack:"$home/etc/initrc-stack"
    n1.startup = {
        def router = agentForService ROUTING
    router.send new RouteDiscoveryNtf(to:4,nextHop:1)
    router.send new RouteDiscoveryNtf(to:2,nextHop:1)
    router.send new RouteDiscoveryNtf(to:3,nextHop:1)
    router.send new RouteDiscoveryNtf(to:5,nextHop:1)
      }
     def n2 =node '2', address: 2, location: [70.m, 0.m, 0.m], shell:5102, stack: "$home/etc/initrc-stack"
  n2.startup = {
    def router = agentForService ROUTING
    router.send new RouteDiscoveryNtf(to:4,nextHop:2)
    router.send new RouteDiscoveryNtf(to:1,nextHop:2)
    router.send new RouteDiscoveryNtf(to:5,nextHop:2)
    router.send new RouteDiscoveryNtf(to:3,nextHop:4)
    router.send new RouteDiscoveryNtf(to:3,nextHop:1)
    router.send new RouteDiscoveryNtf(to:1,nextHop:5)
  }
  def n3 = node '3', address: 3, location: [-70.m, 0.m, 0.m], shell: 5103, stack:"$home/etc/initrc-stack"
  n3.startup = {
    def router = agentForService ROUTING
    router.send new RouteDiscoveryNtf(to:4,nextHop:3)
    router.send new RouteDiscoveryNtf(to:1,nextHop:3)
    router.send new RouteDiscoveryNtf(to:5,nextHop:3)
    router.send new RouteDiscoveryNtf(to:2,nextHop:4)
    router.send new RouteDiscoveryNtf(to:2,nextHop:1)
    router.send new RouteDiscoveryNtf(to:2,nextHop:5)
  }
  def n4 = node '4', address: 4, location: [0.m, 70.m, 0.m], shell: 5104, stack:"$home/etc/initrc-stack"
  n4.startup = {
    def router = agentForService ROUTING
    router.send new RouteDiscoveryNtf(to:1,nextHop:4)
    router.send new RouteDiscoveryNtf(to:2,nextHop:4)
    router.send new RouteDiscoveryNtf(to:3,nextHop:4)
    router.send new RouteDiscoveryNtf(to:5,nextHop:1)
    router.send new RouteDiscoveryNtf(to:5,nextHop:2)
    router.send new RouteDiscoveryNtf(to:5,nextHop:3)
  }
  def n5 = node '5', address: 5, location: [0.m, -70.m, 0.m], shell: 5105, stack:"$home/etc/initrc-stack"
  n5.startup = {
    def router = agentForService ROUTING
    router.send new RouteDiscoveryNtf(to: 1 , nextHop:5)
    router.send new RouteDiscoveryNtf(to: 3 , nextHop:5)
    router.send new RouteDiscoveryNtf(to: 2 , nextHop:5)
    router.send new RouteDiscoveryNtf(to: 4 , nextHop:1)
    router.send new RouteDiscoveryNtf(to: 4 , nextHop:2)
    router.send new RouteDiscoveryNtf(to: 4 , nextHop:3)
  }
}

仿真错误如下：

SEVERE: <3> > Exception in agent: simulator
SEVERE: <4> > Exception in agent: simulator
SEVERE: <1> > Exception in agent: simulator
SEVERE: <5> > Exception in agent: simulator
SEVERE: <2> > Exception in agent: simulator

尽管在每个节点上都加载了堆栈，但并未创建路由。

日志文件统计数据是：

Answer 1

我相信ROUTING服务的规范名称是org.arl.unet.Services.ROUTING。因此，您可能必须使用该字符串，而不仅仅是ROUTING

def router = agentForService org.arl.unet.Services.ROUTING
