An Efficient Event Detection Model that Extends the Lifetime of Wireless Sensor Networks

This is the latest version of this item.

Wireless sensor networks (WSANs) are
increasingly being used and deployed to monitor the
surrounding physical environments and detect events of
interest. In wireless sensor networks, energy is one of the
primary issues and requires the conservation of energy of
the sensor nodes, so that network lifetime can be
maximized. It is not recommended as a way to transmit or
store all data of the sensor nodes for analysis to the end
user. The purpose of this “Event Base Detection” Model is
to simulate the results in terms of energy savings during
field activities like a fire detection system in a remote area
or habitat monitoring, and it is also used in security
concerned issues. The model is designed to detect events
(when occurring) of significant changes and save the data
for further processing and transmission. In this way, the
amount of transmitted data is reduced and the network
lifetime is increased. The main goal of this model is to meet
the needs of critical condition monitoring applications and
increase the network lifetime by saving more energy. This
is useful where the size of the network increases. Matlab
software is used for Simulation.
