Abstract:
In mobile ad hoc networks (MANETs), the provision of quality of
service (QoS) guarantees is much more challenging , mainly due to node
mobility and resource constraints. Most popular routing protocol in
MANET is AODV. The goal of this thesis is to evaluate and optimize the
performance of AODV routing protocol in the virtual classroom
environment by determining an optimal value of performance metrics such
as data rate, queue size and packet size. Groups of different values of
performance metrics are tested using ns-2 simulation to increase the
number of nodes reaching the main node concurrently.
Different values of data rate, packet size and queue size have been
considered to perform the simulation. Accordingly, the simulation results
were analyzed in the form of trace file with their corresponding graphs to
explore the optimum values of performance metrics. According to the
different scenario in the virtual classroom, computers can access the main
node concurrently with acceptable QoS when applying the adaptively
proposed performance metrics and restriction. Furthermore, this result
considers great enhancement when the new QoS metrics are applied.
