Partially overlapping channel assignment for WLANs using SINR interference model

摘要: The use of multiple channels in 802.11 wireless local area networks can improve network performance. Many efforts have been done to better exploit non-overlapped channels. However, the number orthogonal Institute Electrical and Electronics Engineers standards is very much limited. Recent studies indicate that we full-range channel utilization throughput by properly utilizing partially overlapping little work was focused on assignment for In this paper, investigate problem performance based Signal Interference-Noise Ratio interference model. Using model, deduce a direct relationship between maximizing system minimizing total when are employed. After that, propose greedy method minimize maximization. We evaluate our algorithm through extensive simulations compare its performances with those state-of-the-art. Copyright © 2013 John Wiley & Sons, Ltd.
