| Summary: | The rapid development of wireless communication
technologies and portable mobile devices such as laptops, PDAs,
smart phones and wireless sensors brings the best out of mobile
computing particularly mobile ad-hoc and sensor networks.
Nowadays, most of researchers working on Wireless Sensor
Networks (WSNs) focus on Mobile Ad-hoc and Sensor Networks
(MASNETs) due to their wide range of potential applications
ranging from underwater monitoring to search and rescue mobile
robotics applications. In this research work, through extensive
simulation, we have evaluated the capability of Ad-hoc On
Demand Distance Vector (AODV) routing protocol on how far
it can react to different mobility duration of mobile nodes in
MASNETs. The performance of AODV is investigated in terms
of the average percentage of packet loss and energy consumption.
The initial performance study demonstrates that the performance
of AODV is signicantly decreased in mobile environment due
to the frequent topology change in MASNETs. Therefore, in
order to enhance the performance of AODV in MASNETs,
the new routing algorithm based on the estimated distance is
proposed to replace the hop count for the selection of next
node during the packet transmission. The estimated distance is
computed based on the Received Signal Strength Indicator (RSSI)
values that are collected during the communication between the
sensor nodes. The performance of the proposed solution is also
further evaluated and compared with the existing AODV routing
protocol in term of their energy consumption and percentage of
packet loss. Our study demonstrates that the proposed solution
outperform the existing AODV in MASNETs. |
