There has been growing interest in the Mobile WSN applications where mobility is
the fundamental characteristic of the sensor nodes. Mobility poses many challenges
to the routing protocols used in such applications. In this thesis we evaluate the
performance of Collection Tree Protocol as applied in mobile WSN scenarios. The
simulation study shows CTP performs poorly in mobile scenario because of the
frequent tree re-generation resulting from node movements.
We compare Collection Tree Protocol with reactive ad hoc network routing
protocols. The simulation results show that collection tree protocol performs better
than reactive MANET protocols in terms of data delivery ratio and control
overhead under low traffic rates. The end-to-end delay obtained in case of reactive
protocols is also higher compared to that obtained when using CTP, which is due to
their route discovery process.
This thesis presents an improved data collection protocol Fixed Node Aided CTP
based on the analysis of CTP. The protocol introduces the concept of fixed aided
routing into CTP.
It is shown that our enhanced CTP outperforms CTP in terms of data delivery ratio
and control overhead chosen as performance metrics. / UOIT
