Optimizing Practical Adaptive Frequency Hopping and Medium Access Control in Ad Hoc Networks

Adaptive Frequency Hopping (AFH) as proposed, e.g., in IEEE 802.15.2 aims at increasing system reliability in the presence of quasi-static external interference. Practical approaches require autonomous sensing of the interference environment, with the measurements containing both external interference and network self-interference. In prior work, a simplistic model for AFH-based ad hoc networks was developed to analyze how this issue affects the Area Spectral Efficiency (ASE). It was found that the AFH mechanism severely degrades ASE when self-interference is increased.
