ABSTRACT: Wireless sensor network has been used as a landslide monitoring tool for
more than one decade. The robustness of the network is important as the systems
need to survive in harsh conditions. In this paper, we consider the living time
of the sensor network under the influences of the small-scale landslide. We
investigate the performance of famous energy-efficient routing protocol PEGASIS
in both landslide case and non-landslide case. Genetic Algorithm is also
applied to enhance the effectiveness of PEGASIS. The simulation results in this
paper showed that the Genetic Algorithm helps to delay the first node death if
it is used at the beginning of data transmission while being used every round
helps to prolong last node death slightly. The impact of the Genetic Algorithm
on energy usage and route length is also examined. Under the
effect of landslide, with only 70% of energy are spent, the simulated protocols reduced around 30% equivalent route
length while managed to keep the living time up the network up to 90.76%,
comparing to cases with no landslide.
