  abstract = {In wireless sensor networks, the database consists of data collected by the different network nodes. This
database can be accessed by relational queries, such as: selections, projections and joins. Joins are queries that use a lot of
energy, which is a determining factor for network lifetime. In this paper, a new technique for n-way join queries is suggested,
using an in-network processing and adopting the filtering approach. Simulation results showed very good performances of
the proposed technique compared with a central processing of those queries at the sink.},
