AODV(Ad Hoc On-Demand Distance Vector)是一种基于距离向量的自适应路由协议,常用于无线自组织网络中。
以下是一个简单的AODV路由协议实现代码,基于ns-3网络模拟器。
```
#include "ns3/aodv-helper.h"
#include "ns3/aodv-routing-protocol.h"
#include "ns3/core-module.h"
#include "ns3/internet-module.h"
#include "ns3/log.h"
#include "ns3/mobility-module.h"
#include "ns3/network-module.h"
#include "ns3/point-to-point-module.h"
#include "ns3/point-to-point-dumbbell.h"
#include "ns3/wifi-module.h"
using namespace ns3;
NS_LOG_COMPONENT_DEFINE("AodvExample");
int main(int argc, char *argv[]) {
LogComponentEnable("AodvRoutingProtocol", LOG_LEVEL_ALL);
// Create nodes
NodeContainer nodes;
nodes.Create(5);
// Create channels
PointToPointHelper p2p;
p2p.SetDeviceAttribute("DataRate", StringValue("5Mbps"));
p2p.SetChannelAttribute("Delay", StringValue("2ms"));
// Create point-to-point links
NetDeviceContainer devices;
for (uint32_t i = 0; i < nodes.GetN() - 1; ++i) {
for (uint32_t j = i + 1; j < nodes.GetN(); ++j) {
devices.Add(p2p.Install(nodes.Get(i), nodes.Get(j)));
}
}
// Install AODV
AodvHelper aodv;
InternetStackHelper internet;
internet.SetRoutingHelper(aodv);
internet.Install(nodes);
// Set mobility
MobilityHelper mobility;
mobility.SetPositionAllocator(
"ns3::GridPositionAllocator",
"MinX", DoubleValue(0.0),
"MinY", DoubleValue(0.0),
"DeltaX", DoubleValue(10.0),
"DeltaY", DoubleValue(10.0),
"GridWidth", UintegerValue(3),
"LayoutType", StringValue("RowFirst"));
mobility.SetMobilityModel("ns3::ConstantPositionMobilityModel");
mobility.Install(nodes);
// Assign IP addresses
Ipv4AddressHelper ip;
ip.SetBase("10.1.1.0", "255.255.255.0");
Ipv4InterfaceContainer interfaces = ip.Assign(devices);
// Add static routes
Ipv4GlobalRoutingHelper::PopulateRoutingTables();
// Print routing table for each node
for (uint32_t i = 0; i < nodes.GetN(); ++i) {
Ptr<OutputStreamWrapper> routingStream = Create<OutputStreamWrapper>(&std::cout);
nodes.Get(i)->GetObject<AodvRoutingProtocol>()->PrintRoutingTable(routingStream);
}
Simulator::Run();
Simulator::Destroy();
return 0;
}
```
以上代码中,我们首先创建了5个节点和点对点通信信道。然后,我们安装了AODV路由协议,并将其分配给每个节点。接着,我们设置了节点的移动模型,分配了IP地址,并为每个节点添加了静态路由。最后,我们打印了每个节点的路由表,并运行仿真。
