The predominate traffic patterns in a wireless sensor network are many-to-one and one-to-many communication. Hence, the performance of wireless sensor networks is characterized by the rate at which data can be disseminated from or aggregated to a data sink. In this paper, we consider the data aggregation problem. We demonstrate that a data aggregation rate of Θ logn n ( ) can be achieved in wir...

Abstract This study presents a cooperative car‐sharing system in which various service providers jointly operate sharing service. A distributed algorithm is proposed for rebalancing control to reduce deadhead vehicles as much possible under the constraints of dispatchable and parking slots at car stations. Each provider cooperatively searches optimal solution by exchanging estimated values dual...
