In-network aggregation is essential for correlated data gathering in wireless sensor networks
which are resource-constraint in terms of energy, computation and storage. In this paper, we …

The increasing demand on public healthcare service due to the aging population has
become a major problem in developed countries, driving a need to build ubiquitous …

We consider an energy-efficient data aggregation scheme for sensor networks with mobile
access (SENMA), a design that opens the possibility of relieving low-power nodes from …
