| Summary: | Topology change is the main factor that affects the
network life time of Wireless Sensor Network (WSN)
applications. In static WSN, the topology change is often caused
by node failure which is due to energy depletion. However, in the
Mobile WSN (MWSN), the main reason of the topology change is
caused by the node movement. Since the mobile sensor nodes are
limited in power supply and have a low radio frequency coverage,
they are easily losing their connection with neighbours, and have
difficulties updating their routing tables. The switching process
from one coverage area to another consumes more energy that
related to transmitting and receiving association packets. Using
Ad hoc On-Demand Distance Vector (AODV) routing protocol in
MWSN application shows degradation in network performance
due to high density and speed of mobile nodes. In this paper,
through extensive simulation we evaluated the capability of
AODV on how far it can react to network topology change in
MWSN. We investigated the performance metrics namely packet
loss and energy consumption of mobile nodes with various speed,
density and route update interval (RUI). Our performance study
demonstrates that by applying the existing AODV in MWSN, the
results show a high percentage of packet loss and the reduction in
total network energy consumption of mobile nodes if RUI is
getting longer due to serious broken link caused by nodes
movement. We also identify some key research problems that
need to be addressed for successful implementation of AODV in
MWSN. |
