| Summary: | This paper presents an energy-efficient algorithm
based on the connected dominating set (CDS) for a wireless
sensor networks (WSN). A CDS has been widely used for a
virtual backbone construction to support routing and minimize
the communication overheads in a network. Our algorithm, a
single-phase single initiator (SPSI), only requires a single phase
to construct a CDS in a distributed manner using localized
information. It generates a small CDS with low message overhead
and lower energy consumption. Furthermore, it does not rely
on a global positioning system (GPS) to operate and can cope
with the presence of unidirectional links. Therefore, it is simple
and practical to implement. The performance of our algorithm
is confirmed through simulations and validated against two
leading CDS algorithms. The simulation results revealed that our
algorithm is effective in reducing the CDS size, message overhead
and energy consumption. |
