ABSTRACT
The common practice in wireless networking optimization is to address a problem domain, such as channel assignment or transmit power control, and test it across various environments, topologies and traffic rates. This approach, however, provides only a limited context for researchers and administrators, who must decide not only the best combination, but also the best ordering of these independently derived and tested solutions.
This work presents a system architecture and methodology for determining the best features of a configuration of optimizations. These techniques are used to evaluate the joint application of several optimization strategies from five optimization domains, including: channel assignment, association control, transmit power control, bit-rate adaptation and beam form selection. Results from the simulation and field deployment of a 45x45 meter outdoor WLAN show that for the tested scenario: (1) channel assignment should precede association control, (2) minimizing transmit power is ineffective, (3) greedy channel assignment outperforms the Hsum algorithm, (4) load balancing across APs is not significant and (5) null steering is ineffective.
