Abstract

In query-driven sensor networks, query is generally disseminated to the whole sensor. When the query needs information on a specific area, it is unnecessary for the query to be flooded over the entire network. In this paper, we propose a query delivery scheme which does not flood the query over the entire area but only to a restricted area. Also, our scheme also offers fault tolerance capability in order to prolong the network lifetime and to provide reliability for query transmissions. A performance evaluation shows that the total energy consumption can be significantly reduced and the sensor network lifetime can be prolonged by our scheme.
