| Tactical Internet is a tactical communication network in digitized battlefield, which plays an important role in mobile command and control, situational awareness and seamless interchange. Network Coding, which allows intermediate nodes to encode packets before forwarding, improves network throughput. It is of great significance to apply network coding to the tactical Internet.In this thesis, combined with the structural characteristics of Tactical Internet, COPE which is a network coding protocol for multi-hop unicast wireless networks is applied to Tactical Internet to improve network throughput. COPE is realized in the NS-2 simulation software after analyzing COPE principles and algorithms and learning the structure of NS-2. Three different topologies, including small static cluster structure, intensive Tactical Internet and battlefield network, are modeled and their throughputs are emulated in NS-2. Then COPE is applied to the three topologies to emulate its performance. Comparing simulation results shows that COPE can improve the network throughput of Tactical Internet greatly. |
