Cataloged from PDF version of article.We discuss the problem of designing an ad hoc network topology by jointly
using power control and routing. A well-designed topology in ad hoc networks
provides several advantages: increasing the capacity, decreasing the complexity
and reducing the power consumption. We formulate the topology design
problem as an Integer Linear Programming (ILP) model. An optimal topology is
designed subject to interference and connectivity constraints with three different
objective functions and two power control approaches. Common transmit power
(COMPOW) and the adaptive power (ADPOW) are the two different power
control techniques used in this thesis. The objectives of the models that are used
in the topology design are maximizing the number of established links, using
shortest path routing strategy and minimizing the maximum traffic load over the
most congested link by load balancing. Performance comparisons between two
power control approaches with three different objectives in the topology design
are achieved using numerical results on a sample network. Minimum end-to-end
throughput, total throughput, total power consumption and the number of
established links are used as the performance metrics. The numerical results
show that selecting the optimal power for both power control approaches provides similar performance results. Therefore, simplicity of the COMPOW
makes it more attractive than ADPOW in the topology design.Önal, AydoğanM.S
