| Abstract(in English) | Hierarchical routing is effective for large ad hoc networks. However, it is difficult to maintain the hierarchical structure for routing due to node movement. This paper proposes an adaptive method for maintaining the hierarchical structure. The features of the proposed method are(1)the roles of nodes for the hierarchical structure are changed depending on the status of nodes in the restricted vicinity, and(2)the area size is adjusted so that the number of nodes in each area is bounded by two constants. The performance of the proposed method has been evaluated by simulation experiments, which have been done by varying percentage of node movement and speeds of nodes. The results show that node roles efficiently converges to stable states and that change of node roles does not occur so often because of the two features. The proposed method therefore has high adaptability to node movement. |
