A Multi-Nodes Human Body Communication Sensor Network Control Processor

Abstract

This paper presents a low-power body sensor network (BSN) control processor for human body communication (HBC) with the performance of 254 nodes management. The proposed `instantaneous program execution with external program counter' scheme provides up to 10-MIPS performance only when it is needed, and the `TCAM-based period scheduler' manages 254 HBC nodes with 21.6-muW power consumption. They are verified by the implementation of the BSN controller and shows 254 nodes management with 4.2-MIPS performance.
