| Outline of Final Research Achievements |
In wireless multi-hop networks, reducing the redundant flooding traffic is crucial. Some network coding methods to reduce the burden of flooding have been proposed. However, the dynamic nature of the network topology, which is subject to changes due to node mobility and joining/leaving, necessitates the development of adaptive network coding methods. This study proposes a new adaptive network coding method that adapts to network topology changes. We conducted computer simulations to evaluate the efficacy of the proposed method. We found that it outperforms existing methods in terms of network load performance without compromising the packet delivery rate.
