WLAN Channel Assignment Based on Channel Overlap Factor

Abstract

A channel assignment model for WLAN is proposed. In unlicensed 2.4 GHz IS M band, there are only 3 nonoverlapping channels for IEEE 802.11g WLAN. To make use of all available channels and reduce inter-channel interference in channel assignment, channel overlap factor is introduced in this paper, which is calculated according to the level of overlap between channels. An integer programming model, which aims at maximizing the minimal S IR, is then proposed based on channel overlap factor, and simulated annealing algorithm is applied to solve this model. Simulation results show that the proposed channel assignment model is capable of significantly increasing the minimal S IR.

“…When we compared staining between slides A and B for the same antibodies and cycle number, the overlap in intensity distributions was high (>0.85), demonstrating good sample to sample reproducibility ( Zhou and Liu, 2012 ). The overlap remained high for the majority of antibodies even when they were used in different cycles on slides A and B, but for some antibodies, signal intensity clearly increased or decreased with cycle number ( Figure 6D ; blue and red outlines).…”
