on-body wireless or body-centric wireless is the interconnection and networking of wearable computer system components and sensors through a system of transceivers, space wave antennas, and surface guided wave antennas for telemetry and telecommunications. the technique uses the surface of the human body as a transmission medium or path for electromagnetic waves. the topic of body-centric wireless networks (bcwn) can be divided into three main domains based on wireless sensor nodes placement, i.e., communication between the nodes that are on the body surface; communication from the body-surface to nearby base station; and at least one node may be implanted within the body. these three domains have been called on-body, off-body and in-body, respectively. the performance analysis of on-body wireless communication for different sporting activities has been reported .
