In ad hoc networks, it is effective that each mobile host creates replicas of data items held by other mobile hosts for improving data accessibility. When a mobile host requests a data item (replica) held by another mobile host, it usually uses the shortest path for the data transmission. In this case, mobile hosts at the center of the network relay many data items and consume much power. In this paper, we propose a data access method to balance the power consumption among mobile hosts. This method selects a path between the request issuing host and the requested data holder considering the path length and the remaining amount of batteries of mobile hosts along the path. We present simulation results to evaluate the performance of our proposed method.
