Research On Network Coding Capacity Of MANET

Nowadays, the problem of network coding capacity has become a hot topic. Previous work on network coding capacity of wireless networks has focused on the assumption that the network is stationary. However, in this paper, network coding capacity is studied in dynamic network caused by the node's mobility.On the one hand, this paper first studies the network coding capacity of MANET without the consideration of noise and interference. The weighted random geometric model is used to model MANET; we judge the connection of two nodes by the distance between them and verify the concentration feature of network coding capacity with the help of Chernoff Bound Theorem. And then, we have simulated the network coding capacity under the condition of different mobility models and diverse network connectivity degrees.On the other hand, this paper makes a research on the network coding capacity of MANET with the consideration of noise and interference. Here the most common SINR model is used to judge whether the two nodes are well connected. Considering the fact that the network model is changeable with noise and interference, network coding capacity's concentration feature can be concluded from the reference [31] using the Coupling Methods. At last, we also apply the Ford-Fulkerson Method to simulate the MANET's network coding capacity under the condition of different mobility models.
