Realization of Public M-Health Service in License-Free Spectrum

---

Abstract—Public m-health is a new medical service under intensive development, which provides unobtrusive monitoring of people’shealthconditionsfromanywhereatanytimetoenabledetection of deteriorating health conditions before severe discomfort or disability occur. A key challenge in practical implementation of public m-health is the use of shared license-free spectrum by body area networks (BANs) to report sampled vital signs continuously and in real time. A cognitive medium access control method calledcentralizedbodyareanetworkaccessscheme(CBAS)isproposedinthispapertoreduceaccessdelayinaBANinthepresence of coexistent systems. By opportunistic extraction of idle spaces from a pool of orthogonal channels, CBAS dynamically adjusts a BAN’schannelaccesspatternaccordingtothecurrentinterference environment, and improves the BAN’s visibility among coexistent networks.PerformanceofaBANunderCBASisanalyzedbymodelingthesystemasapreemptive-resumepriorityqueue.Numerical and simulation results show that the queuing delay and throughput of a BAN employing CBAS outperforms those of a BAN that utilizes a single channel statically, as channel access opportunities suffer less fragmentations and interruptions.

Index Terms—Body area network (BAN), coexistence, licensefree spectrum, m-health, medium access control (MAC).
