Abstract
Sensor-cloud has been perceived as a potential paradigm for executing wireless sensor based applications. In sensor-cloud, the underlying sensor network is highly heterogeneous in terms of the hardware, sensing and communication ability, and other configuration issues. Thus, the transmission from the underlying networks to the cloud is challenging and induces research interest. The underlying physical sensor nodes for a virtual sensor network (VSN) that transmit the data through a set of intermediate nodes, namely, the bridge nodes to the cloud. This work focuses on obtaining an optimal decision rule to select a bridge node on behalf of a VSN. The work achieves the reduce energy consumption of every node which, in turn, improves the energy expenditure of the entire VSN.
