For hospital e-health systems, a novel medium access control (MAC) scheme that achieves delay-sensitive healthcare traffic (DSHT) delivery in the uplink direction of wireless local area networks (WLANs) is proposed and investigated. By introducing a slotted request uploading period and informing hubs to upload their transmission requests orderly during the period, overhead cost associated with frequent transmitter/receiver transitions can be reduced and polling empty hubs can be eliminated. Cons...

We have numerically demonstrated a high-speed bidirectional chaotic communication, where chaotic optical signal with suppressed time delay signature is used. In this scheme, the output of a third semiconductor laser is used as the common signal driving the other two identical lasers with self-feedback to be synchronized. To enhance the bandwidth of the chaotic signal employing in the communication, part of output of the driven laser is coupled into the third laser and appropriate frequency detun...

An energy-efficient optical access network scheme based on sub-band grouping and allocating is proposed and studied for the digital filter multiple access adopted passive optical network (DFMA-PON). In this scheme, sub-bands generated in digital sdomain are grouped as band groups and properly allocated for optical network unit (ONU) transmissions to reduce the transmission time. Based on this, longer sleeping time can be provided to each ONU, and some more energy can be saved. Numerical evaluati...

Chaos generated by a semiconductor laser subject to self-phase-modulated optical feedback is proposed, where the time-delay-signature is concealed and complexity is enhanced. Fascinatingly, the probability density distribution of its output intensity is close to symmetry.

We propose and numerically demonstrate a secure key distribution scheme based on the dynamic chaos synchronization of two external cavity vertical-cavity surface-emitting lasers (VCSELs) subject to symmetric random-polarization injections. By exchanging the random parameters that control the polarization angles of the driving injection, Alice and Bob can identify the time slots in which high-quality private chaos synchronization is achieved and independently generate a shared key from the synchr...

A new secure key distribution scheme based on the dynamic chaos synchronization of two cascaded semiconductor laser systems (CSLSs) subject to common chaotic injection and random phase-modulated optical feedback is demonstrated. In this scheme, Alice and Bob adopt two independent random sequences to control the phase modulators of CSLSs, which induces a dynamic perturbation to the chaos synchronization. We thoroughly investigate the chaos synchronization performance under different phase-shift c...

Chaotic semiconductor laser is a good candidate for secure communication and high-speed true random bit generator, for its characteristics of broad bandwidth and prominent unpredictability. Based on the synchronization property and true random bit generation characteristic of chaotic semiconductor lasers, physical secure key distribution is available. In this work, we majorly show three key distribution schemes stemming from synchronized chaotic semiconductor lasers or chaos-based key exchange p...
