| Abstract(in English) | In wireless multihop networks, collisions and contentions of wireless signals caused by exposed- and hidden-terminal problems results in longer transmission delay of data messages. Though avoidance and/or reduction of collisions between neighbor nodes in different transmission routes is important, introduction of detour routes only causes longer end-to-end transmission delay. In order to solve this problem, this paper proposes on-demand and localized route modification by applying the following two algorithms; one is route separation algorithm by replacement of an intermediate node and the other is route separation algorithm by addition of an intermediate node. These algorithms work only for adjacent transmission routes. For intersect transmission routes, it is impossible for the algorithms to be applied for route separation. Hence, we propose the method to introduce an intersection node of them and to apply the network coding in order to reduce the performance reduction of neighbor transmission routes. The proposed overhearing method drastically improve applicability of the network coding method and it is expected to improve the performance of data message transmissions. |
