This paper proposes a self-organizing technique for enhancing
the coverage of wireless micro-sensor networks after
an initial random placement of sensors. A randomized
back-off delay time is introduced to resolve the problem
of simultaneous movement of sensors in the neighborhood
which will lead to unnecessary excessive movement and
hence consume more sensors' energy. A sensor node will relocate
itself when the time calculated through randomized
back-off delay computation is reached. The new location
of the sensor is determined by a virtual force-directed algorithm
where virtual attractive or repulsive forces exerted
by other sensors or obstacles are used to guide the sensor
to the desired location. The proposed self-organizing algorithm
for sensor placement is proved to be effective through
simulation.
