ABSTRACT

In this paper, we investigate cross-layer optimization performance based on real-life experimental measurements, at the physical and network layers, across coexisting wireless body area networks (BANs). At the network layer, the best possible route is selected according to channel state information from the physical layer. Two types of dynamic routings are applied - shortest path routing (SPR), and novel cooperative multi-path routing (CMR) incorporating 3-branch selection combining. These routing techniques are used for performing real-time, reliable data transfer across BANs operating near the 2.4 GHz ISM band. An open-access experimental data set incorporating 'everyday' mixed activities is used for implementing and analyzing the proposed cross-layer optimization. In terms of outage probability, negligible packet error rate is achieved by applying CMR and SPR techniques with reasonably sensitive receivers. Moreover, up to 8 dB performance improvement is gained by applying CMR over SPR, at 10% outage probability. The amount of end-to-end delay obtained from SPR and CMR schemes are 76 ms and 129 ms, respectively. Also, the combined channel gains across SPR and CMR are lognormal and Weibull distributed, correspondingly. The acquired empirical results comply with the IEEE 802.15.6 Standard for packet error rate and latency for both medical and non-medical BAN applications.
