Abstract
In this paper we introduce the technical specifications defined for relay functionality for ETSI SmartBAN (Smart Body Area Network). The specifications extend the general medium access control (MAC) framework defined for SmartBAN by defining a two-hop communication within a SmartBAN. The extension enables longer distances between the devices and the hub and guarantees connectivity in poor channel conditions. Any relay connectivity is established as a joint effort of the hub and the node, termed as isolated node, seeking the relay connection. Unlike methods described in the literature, the ETSI SmartBAN relay functionality does not introduce additional (external) relay nodes; the method is based on utilizing a normal device as a temporary relay.
