Abstract: Wireless Sensor Network (WSN)
refers to a group of locationally dispensed and dedicated sensors for observing
and recording the physical conditions of the environment and coordinating the
aggregated data at a centrical location. To serve such new applications,
localization is largely used in WSNs to define the current location of the
sensor nodes. Time of Arrival (ToA) localization is one of the prevalent schemes
due to its high estimation accuracy. ToA is a method to estimate the location
of a target based on the correlation of the signals and calculating the
distances from each anchor to the target by multiplying the speed of light and
the time at which the signal is received. In our recent study, we propose
Modified 3N algorithm in 2D space. In the Modified 3N algorithm in 2D, three
circles were used to localize the target nodes in the network. In this paper; Uniform,
Beta, Weibull, Gamma and Generalized Pareto distributed networks are used for
localization with the Modified 3N algorithm in 2D and the localization
performance of the networks are evaluated and compared using MATLAB
simulations. For these simulations, firstly, constant communication range of
10% of the field dimension is used and then dynamic communication ranges that
depend on the number of total nodes are used for the same areas.
