In sensor networks, the large amount of data generated by sensors greatly influences the
lifetime of the network. To manage this amount of sensed data in an energy-efficient way …

Wireless sensor networks (WSN) are composed of several sensors having limited memory,
processing power, communication bandwidth, and energy, which cooperate in performing a …

In the recent past, search in sensor systems focused on node hardware constraints and very
limited energy resources. But nowadays, that new applications need data processing with …

The emergence of sensor networks as one of the dominant technology trends in the coming
decades (Technol. Rev.(February 2003)) has posed numerous unique challenges to …

The widespread dissemination of small-scale sensor nodes has sparked interest in a
powerful new database abstraction for sensor networks: Clients “program” the sensors …

Over the past few years, a great deal of attention in the networking and mobile-computing
communities has been directed towards building networks of ad-hoc collections of sensors …

In wireless sensor networks (WSNs), energy is valuable because it is scarce. This causes
their life time to be determined by their ability to use the available energy in an effective and …

Existing sensor network data aggregation techniques assume that the nodes are
preprogrammed and send data to a central sink for offline querying and analysis. This …

In this article, we consider energy-efficient implementation of the SQL join operation in
sensor databases, when the join selection condition is a range predicate. Apart from two …

With the price of wireless sensor technologies diminishing rapidly we can expect large
numbers of autonomous sensor networks being deployed in the near future. These sensor …
