Design and Implementation of a Circuit for Mesh Networks with Application in Body Area Networks

This paper presents a network circuit for wearable low-power BAN (Body Area Networks) applications, geared towards mesh network topologies with conductive yarns as transmission channels. The design and implementation of the physical and MAC layers is described. The resulting circuit sends and receives data simultaneously, and experimental results indicate that the proposed system works with variable data rates, up to a maximum of 9+9 Mbps. All reported measurements were collected from working FPGA-based prototypes, and the performance achieved shows that the circuit is suitable for use in reliable high-speed low-power BAN applications.
