Abstract
The deployment of highly dense wireless local area networks (WLAN)
can cause an excessive level of interference in the commonly used 2.4 GHz ISM
band, which leads to network performance degradation. This paper analyses the
possibility to reduce congestion in the crowded ISM band by allowing some access
points (APs) to opportunistically operate in a primary band. Although the problem of
opportunistic channel allocation considering both ISM and primary bands can be
formulated mathematically as a Binary Linear Programming (BLP) problem, existing
algorithms (e.g., branch and bound) capable to provide optimal solutions for BLP
problems are quite inefficient for large deployments. Therefore, we propose three
different heuristic algorithms to solve this opportunistic channel allocation problem
by properly extending graph coloring algorithms: First Fit (FF), Saturation Degree
Ordering (SDO) and Minimum Spanning Tree (MST). A performance analysis of the
three algorithms is carried out under different conditions of primary band availability
and AP density
