is the desired end-of-period synchronization probability. he ARSP
is also lightweight and provides some tunable service such as changing the desired end-of-period
synchronization probability and increasing the maximum synchronization error allowed.
In summary, the above mentioned timing techniques may be used for different types of applica-
tions; each of them has its own benefits. All of these techniques try to address the factors influencing
time synchronization while design according to the challenges as described in Section .. Depending
on the types of services required by the applications or the hardware limitation of the sensor nodes,
some of these timing techniques may be applied.

5.6 Conclusions
he design challenges and factors influencing time synchronization for sensor networks are described
in Sections . and ., respectively. They are to provide guidelines for developing time synchro-
nization protocols. The requirements of sensor networks are different from traditional distributed
computer systems. As a result, new types of timing techniques are required to address the specific
needs of the applications. hese techniques are described in Section .. Since the range of applica-
tions in the sensor networks is wide, new timing techniques are encouraged for different types of
applications. his is to provide optimized schemes tailored for unique environments and purposes.
