摘要：In Wireless Sensor Networks, data dissemination to multiple mobile sinks consumes a lot of energy. Various grid-based data dissemination strategy [12] has been proposed over the years to reduce the energy consumption in Wireless Sensor Net works. In this paper, we have proposed an energy aware data dissemination strategy for reducing the energy consumption during grid construction, dissemination node failure handling and data and query forwarding. The proposed EGDD scheme uses a single virtual grid for data dissemination and sensor nodes are energy aware so a data dissemination node is replaced by an alternate dissemination node as soon as its residual energy reaches to a predefined threshold value. We have proposed a novel scheme for det ermining the cell size of the grid, selecting the dissemination nodes and alternate dissemination nodes. The proposed scheme reduces the energy consumption during the query and data forwarding and handling dissemination node failure. It also solves the problem of sink mobility. Theoretical analysis shows that the proposed EGDD scheme performs better than the existing the data
