Ad hoc on-demand distance vector (AODV) is an often used routing protocol in multihop communication. In AODV, there is a tendency for the first established route to be repeatedly used. This causes a problem that the remaining battery levels become uneven between the nodes used in the communication route and the other nodes. In this paper, we propose a simple route reconstruction method to ease the problem. The proposed method makes use of the sequence number that is used in the conventional AODV. We conduct a fundamental investigation into the lifetime of the first-dead node using a network simulator. The result shows that the proposed method with multiple thresholds can prolong the lifetime of the first-dead node by 11%. This means that the proposed method can contribute toward easing the problem of uneven battery consumption among the nodes.
