The appropriate method to store sensed data depends on the applications. In this study, a data storge scheme called Distributed Index-based Dominating Set (DIDS) was proposed to reduce the communication cost for transmitting data and to efficiently process data queries. This scheme is based on the idea that sensing data are stored at the nodes closed to the detecting nodes and the location information of these storing nodes is pushed to some index nodes closed to them.So queries are only needed to be routed to the index nodes instead of flooding into the whole network. Therefore, the DIDS scheme can minimize the use of limited network and computational resources while providing timely responses to queries. Moreover, This data dissemination scheme also disscusses load balance. Analysis and simulations show that the DIDS scheme outperforms the External Storage (ES) based scheme, Local Storage (LS) based scheme and the Data Centric Storage (DCS) based scheme.]]>Akyildiz, I.F., W.
