Distributed channel adaptation using instantaneous clusters in energy-constrained multi-hop wireless networks

Abstract

This paper proposes a practical lightweight scheme for channel problem detection and adaptation in energyconstrained multi-hop wireless networks. Generally, handheld devices such as smart phones have functional constraints that limit them from utilizing multiple radio interfaces. Even with these limits, these nodes must be able to efficiently detect and avoid interfered channels. We propose a novel channel sensing and adaptation method that is suitable for these environments, and analyze it through implementation to prove its superiority.
