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 (BBC) 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 HIBC nodes with 21.6-mu W power consumption. They are verified by the implementation of the BSN controller and shows 254 nodes management with 4.2-MIPS performance.
