Mobile Ad Hoc Networks pose challenges in terms of power control, due to their fixed
transmission power, the mobility of nodes and a constantly changing topology. High
levels of power are needed in wireless networks, particularly for routing. As a result of
the increase in the number of communication devices being used, there is the challenge
of increased density within these networks, and a need to extend the battery life of communication
devices.
In order to address this challenge, this thesis presents the development of a new protocol
(Dynamic Power AODV), which is an enhancement of the Ad Hoc On Demand Distance
Vector (AODV) protocol. The new protocol dynamically adjusts the transmission power
based on the range, which depends on node density.
This thesis provides a systematic evaluation of the performance of DP-AODV, in a high
speed and high density environment, in comparison with three other routing protocols.
The experiments demonstrated that DP-AODV performed better than two of the protocols
in all scenarios. As compared to the third protocol (AOMDV), DP-AODV gave
better performance results for throughput and Power Consumption, but AOMDV performed
better in terms of Packet Delivery Fraction rate and End-to-End Delay in some
cases
