Proximity-based access control for implantable medical devices
We propose a proximity-based access control scheme for implantable medical devices (IMDs). Our scheme is based on ultrasonic distancebounding and enables an implanted medical devi...

Distributed Opportunistic Scheduling With Two-Level Channel Probing
Distributed opportunistic scheduling (DOS) is studied for wireless ad-hoc networks in which many links contend for the channel using random access before data transmissions. Simpl...

Three-Stage Serially Concatenated Codes and Iterative Center-Shifting K-Best Sphere Detection for SDM-OFDM: An EXIT Chart Aided
—Iterative K-best sphere detection (SD) and channel decoding is appealing, since it is capable of achieving a nearmaximum-a-posteriori (MAP) performance at a low complexity. Howe...

Quantize-and-Forward Relaying with M-ary Phase Shift Keying
Abstract—Using cooperative transmission, two or more singleantenna users can share their antennas to achieve spatial diversity in a slow fading channel. One relaying protocol tha...

Routing with a Markovian Metric to Promote Local Mixing
— Routing protocols have traditionally been based on finding shortest paths under certain cost metrics. A conventional routing metric models the cost of a path as the sum of the...
