我只在没有任何 shellcode 的情况下从代理在 UnetStack 中创建我的路由。我想从路由表中删除一条路由?
以下是我的代码:
我要做的是每 10 秒在两条路线之间切换一次。所以从我的源节点(节点 5)到我的目标节点(节点 1),路由从 5 变为 3 变为 4 变为 1 或从 5 变为 2 变为 4 变为 1
模拟
platform = RealTimePlatform
channel.model = ProtocolChannelModel
channel.soundSpeed = 1500.mps // c
channel.communicationRange = 100.m // Rc
// run the simulation infinately
simulate {
// Destination node
node '1', remote: 1101, address: 1, location: [ 0.m, 0.m, 0.m], shell: 5101, stack: { container ->
container.add 'new_routing_agent', new new_routing_agent();
container.add 'routing', new Router();
container.add 'rdp', new RouteDiscoveryProtocol();
}
node '2', remote: 1102, address: 2, location: [ 0.m, 0.m, -75.m], shell: 5102, stack: { container ->
container.add 'new_routing_agent', new new_routing_agent();
container.add 'routing', new Router();
container.add 'rdp', new RouteDiscoveryProtocol();
}
// neighbor node for node 5, and will be a next node for node 5 during routing
node '3', remote: 1103, address: 3, location: [0.m, 0.m, -90.m], shell: 5103, stack: { container ->
container.add 'new_routing_agent', new new_routing_agent();
container.add 'routing', new Router();
container.add 'rdp', new RouteDiscoveryProtocol();
}
//Neighbor node for node 5 ,but not a next node for node 5
node '4', remote: 1104, address: 4, location: [0.m, 0.m, -150.m], shell: 5104, stack: {container ->
container.add 'new_routing_agent', new new_routing_agent();
container.add 'routing', new Router();
container.add 'rdp', new RouteDiscoveryProtocol();
}
// Source node
node '5', remote: 1105, address: 5, location: [0.m, 0.m, -160.m], shell: true, stack: {container ->
container.add 'new_routing_agent', new new_routing_agent();
container.add 'routing', new Router();
container.add 'rdp', new RouteDiscoveryProtocol();
